3 Marathon Series Corrosion-Resistant Mounted Products and Bearing Units Few industries challenge bearings with a harsher operating environment than the food and beverage industries. Perhaps no industry works as hard to meet regulations governing contamination. When MRC introduced the Marathon Series Composite Mounted Bearing Units, it was possibly the best solution to the problems associated with bearing failures. Now the composite units are joined by our HD i heavy-duty cast iron and XD s extreme-duty cast stainless steel to more thoroughly meet the needs of the industry. The HD i Series was developed to provide corrosion resistance together with the strength of cast iron but eliminate the problem of flaking nickel plating. These units consist of a ZMaRC coated cast iron housing in combination with a ZMaRC coated insert bearing and are priced competitively with other nickel-plated versions. (See page for more details.) For extremely challenging applications, MRC offers the XD s Series, with top-of-the-line corrosion resistance and the greatest housing strength available within the Marathon line. These housings utilize an AISI 00 series cast stainless steel housing together with MRC s proven stainless steel insert bearing. (See page 4 for more details.) The entire maintenance-free Marathon Series is built to resist corrosion and is designed for extended service life. At the heart of the units are high-quality, corrosionresistant insert bearings, available with MRC s ZMaRC coating or with stainless steel construction. The units multifunction low-friction, rubber seals are bonded to AISI 04 stainless steel for superior corrosion resistance, and sealed-for-life lubricants are USDA approved.

4 A Composite Housing with Integrated Performance Features The Marathon Series composite housing resists citric acids, cooking fats and most chemicals used in food and beverage processing. It is constructed of a thermoplastic composite material that can be up to 6% lighter than cast iron housings. Its spherical bore accommodates the insert bearing s spherical outer surface, enabling the unit to fully compensate for initial bearing seating misalignment. Plus, the housing is loaded with design and performance advantages: Steel coils embedded in the housing contribute to the housing s fracture strength. Radial breaking load is far greater than the static load rating of the bearing. Marathon Series housings have possibly the highest fracture strength of any composite unit available. Apolyurethane-filled housing base enables the unit to meet flush with its mounting surface. Flush surface-tosurface mounting eliminates gaps potential areas for contaminants to collect. 00 Series stainless steel bolt hole inserts provide added strength to each housing foot and prevent corrosion. Marathon Series units are available in the following housing designs to meet the needs of most food and beverage processing applications: pillow blocks two- or four-bolt flange tapped base three-bolt bracket flange narrow and wide slot take-up low backing height pillow block low profile two- and three-bolt flange four-bolt piloted flange hanger 04 stainless steel set screws 20 degrees apart. Choice of ZMaRCcoated or stainless steel insert bearing. Polyurethane-filled base. No gaps where contaminants can collect. 04 stainless steel double contact seal and flinger. Insert bearing is prelubricated with USDA approved grease. Light gray polyamide composite housing resists corrosion. Polyamide Cage. Stainless steel bolt hole inserts. 2

5 NEW! ZMaRC Coated Cast Iron Units with ZMaRC coated Insert Bearings MRC s newest solution to the unique needs of the food processing industry is Marathon HD i a new corrosionresistant, heavy-duty cast iron series of bearing units. The cast iron housings, protected with MRC s proven ZMaRC coating, eliminate the flaking problems associated with nickel-plated products. The housings are matched with our ZMaRC-plated, lubed-for-life, quality insert bearings. The HD i series provides a number of cost-saving and performance benefits. As with all Marathon products, MRC s patented two-part stainless steel seals allow the units to operate in heavy washdown environments without regreasing. And since there is no need for relubrication, continuous grease purge is never a problem. Advantages of the HD i Series: Complete ZMaRC coating on all housing surfaces for long-term corrosion resistance. ZMaRC coating will not flake off. Housings and bearings are resistant to the majority of common washdown solutions. HD i units require no relubrication, even in a washdown environment saving time and money while providing a cleaner-running unit. Open spaces on bases and backs of ZMaRC-coated housings are filled with polyurethane, eliminating areas where moisture and product can collect, resulting in a more sanitary housing design. All HD i units are factory lubed-for-life with USDA approved H grease. Two-part sealing for maximum protection Like all Marathon bearing units, Marathon HD i units contain an AISI 04 stainless steel inner seal and outer seal. These components work in tandem to form an extremely effective sealing system. (See page 5 for more details.) The added strength and durability of the Marathon HD i housings make them particularly well suited for applications in red meat, pork and poultry processing facilities where both housing strength and corrosion resistance are a concern. The HD i Series is available in the following housing designs: pillow blocks two- or four-bolt flange tapped base

6 Extreme Duty Cast Stainless Steel Mounted Units Composite housing units are suitable for many food and beverage industry applications. However, there are extremely challenging applications that require a even more durable unit the XD s line of Marathon units. These housings are AISI 00 series cast stainless steel with MRC s proven stainless steel insert bearings. The cast stainless housings are the strongest housings offered in the Marathon family. For any application where loads are very heavy or where shock loads are possible, the extra strength and toughness of the stainless steel housings are a benefit. Also, in applications where failure of the housing could result in injury, such as in cases where workers pass below a portion of a machine, the safety factor inherent in the cast steel housing is desirable. Exposure to extremely aggressive washdown chemicals is another reason to choose these stainless units. While composite and plated housings are resistant to most of the chemicals in use today, they can be susceptible to some strong concentrations of chlorine, hydrogen peroxide and other chemicals. The cast stainless housings, made of an AISI 00 series stainless material, are not affected by those same chemicals. The XD s cast stainless housings were designed from the ground up for use in food and beverage applications. The bases are cast flat with no recesses to trap debris and bacteria, and the exposed surfaces of the housings have no unnecessary crevices or pockets. Consideration was given to surface roughness as well. The XD s units smooth cast surfaces minimize the material trapped on the surface allowing a more thorough cleaning. the application involves heavy loads, aggressive chemicals or intolerance to bacteria buildup, the XD s units are up to the challenge. Housing styles available include: pillow block two- and four-bolt flange tapped base MRC XDs Extreme Duty Machined Stainless Steel Mounted Units MRC can also offer additional housing styles in machined stainless steel. These units also utilize AISI 00 series stainless steel but, rather than using a cast housing, these units are machined from solid stainless plate. Due to this manufacturing difference, these housings offer even better surface roughness since all surfaces are machined. These are especially suited for applications where surface roughness is critical, such as instances where chronic bacterial problems have existed. As with the cast housings, there are no unnecessary recesses or cavities to trap debris. Just like the cast stainless units, MRC s excellent stainless steel insert bearings are used. In addition to the styles listed above, are available in housing styles: three-bolt bracket flange wide and narrow slot take-up units compact two- and three-bolt flange piloted flange units All machined housings are available through the MRC MTO (Made To Order) program. Like the other members of the Marathon family, the XD s series incorporates the proven insert bearing design and patented sealing arrangement (see page 5), and are also greased for life and maintenance free. Marathon XD s is MRC s top of the line unit. Whether 4

7 Choose from ZMaRC-coated The Marathon Series is designed to withstand food processing environments. The unit s high quality insert bearing is available with MRC s proprietary ZMaRC coating on the inner and outer rings. ZMaRC resists frequent wash downs with water and with acidic and caustic solutions far better than conventional insert bearings and conventional coatings, such as black oxide. In food and beverage applications, that means greater protection against rust, greater protection against contaminant-related bearing failure and greater assurance that your equipment will pass USDA inspections....or Stainless Steel Insert Bearings If you prefer stainless steel, MRC will supply the Marathon Series with AISI 420 C stainless inner and outer rings and balls. Both ZMaRC-coated and stainless steel insert bearings come in bore sizes ranging from /4" to /2", and 20 mm to 40 mm. ZMaRC is also available in 5 /6". The insert bearing s stainless steel set screws, positioned 20 degrees apart, minimize inner ring distortion while maintaining good gripping strength. A Stainless Steel Sealing Arrangement Double-guards Against Contaminants A double-protection seal keeps Marathon Series Mounted Bearing Units running contaminant free. The sealing arrangement consists of a double-lip, AISI 04 stainless steel insert seal, an AISI 04 stainless steel flinger and a rubber-backed seal gasket. The flinger and seal s lowfriction rubber lips, with optimized axial contact, form a double barrier against pollutants and wash downs. The seal gasket prevents contaminants from migrating around the seal insert s O.D. The flinger adds mechanical and centrifugal protection against contaminant entry. The space between the insert seal and flinger is filled with USDA Food Grade grease for even greater sealing efficiency. USDA-approved Grease Marathon Series Composite Mounted Bearing Units are prelubricated-for-life with USDA H-approved grease. The high quality synthetic grease is odorless and tasteless, leaving foodstuffs unaffected by lubricant contact. It is approved for use in all food processing industries, including meat, fish, poultry and fruit processing equipment. And it resists washout, even during frequent washdowns with hot and cold water, and with disinfectant solutions. Other Marathon Mounted Bearing Unit grease benefits: Excellent internal and external bearing corrosion protection. High aging resistance for extended lubricant life. High load carrying capacity, which helps prevent premature bearing wear. 5

34 Marathon Hi-Temp and Submersible Units MRC Hi-Temp and Submersible Units are fitted with high performance plane bearing inserts specifically designed for these demanding applications. The inserts can be assembled into any of the Marathon housing styles which MRC currently offers. Rotation of the insert in the housing is prevented by means of an anti-rotation slot in the outer ring mating with the set screw inserted into the housing, while still allowing self-aligning capability. These units provide superior performance in applications which would normally cause premature failure of standard anti-friction bearings requiring lubrication. As with all Marathon products, these units provide improved service life, and do not require lubrication since the polymer is the friction reducing component. Therefore, they are maintenance free and there is no excessive grease purging, which is usually an issue when trying to extend the service life of a bearing in severe operating environments. Marathon High Temp and Submersible Plane Bearing Units are suitable for a wide range of applications in addition to high temp and submersible conditions. They meet USDA approval for direct contact in meat, poultry and dairy applications, and are suitable for a wide range of food applications where washdown and corrosion are problems. Marathon Plane Bearing Units Marathon plane bearing inserts meet many food and non-food application requirements. They are suitable for a wide range of food applications where corrosion is a problem; they can be selected to operate in temperature ranges from cryogenic to 600 F and can be mounted horizontally or vertically; they can also be supplied to handle different loading and speed conditions. And as with all Marathon inserts, lubrication is not required, resulting in simplified maintenance-free operation. Non-stock plane bearing units can be supplied through the MRC Made-To-Order (MTO) program. The normal lead time for a non-stocked variant is approximately six weeks. Submersible part number examples: '' Composite pillow block CPB00SB 6'' Composite 2-bolt flange C2F0SB '' Composite tapped base CTB08SB High temparture part number examples: '' ZMaRC cast iron pillow block ZPB00HT 6'' ZZMaRC cast iron 2-bolt flange Z2F0HT '' ZMaRC cast iron 4-bolt flange Z4F08HT Submersible part number examples: '' Stainless pillow block SPB00SB 6'' Stainless 2-bolt flange S2F0SB High temparture part number examples: '' Stainless pillow block SPB00HT 6'' Stainless 2-bolt flange S2F0HT 2

35 High Temperature Insert Plane Bearings (HT) Set Screw Locking MRC High Temperature Plane Bearing Inserts can withstand consistant temperatures up to 500 F. When normal anti-friction bearings cannot handle the heat, MRC High Temperature Plane Bearings are the best choice to keep rotating equipment running smoothly. The 6 stainless steel inner ring and 04 stainless steel outer ring offer wear resistance as well as corrosion resistance. The high performance polymer sleeve material allows the bearing to operate at higher speeds compared to typical plane bearings. Since the polymer material is the friction reducing component, no grease is required for proper performance. In the event of premature wear, the insert bearing will not catastrophically fail but will exhibit looseness, indicating that the bearing needs to be replaced. The recommended Marathon housing material for this insert is either the ZMaRC -coated cast iron or cast stainless steel to meet most application requirements for high temperature duty. In addition, the insert bearing is approved for incidental food contact by the USDA/FDA. For inch shafts 4 to 5 6. Metric inserts can be supplied through the MTO Program.

36 Submersible Insert Plane Bearings (SB) Set Screw Locking MRC Submersible Plane Bearing Inserts are suitable for applications which are constantly exposed to or submerged in moisture. When normal anti-friction bearings fail because of grease washout or corrosion, MRC Submersible Plane Bearings are the best choice to keep rotating equipment running smoothly. The 6 stainless steel inner sleeve offers wear resistance as well as corrosion resistance. The high performance polymer outer ring allows the bearing to operate at moderate speeds without the need for lubrication since the polymer material is self lubricated. The polymer material can withstand continuous temperatures up to 50 F, and tolerates higher temperatures during washdown. The insert bearing will not catastrophically fail; it wears by becoming loose in the bore. The recommended Marathon housing material for this insert is either composite or cast stainless steel. In addition, the insert bearing is approved for direct food contact by the USDA / FDA. For inch shafts 4 to 5 6. Metric inserts can be supplied through the MTO Program.

39 Picker Hub Applications Stainless Steel Bearings with Solid Lubricant Pack (W64F) Single row deep groove (SRDG), doubled sealed, stainless steel ball bearings are available with solid lubricant pack in a food grade formulation identified as W64F. This lubricant is USDA approved for use in food related applications with incidental food contact. It has excellent oil lubricating properties and helps prevent grease washout and contamination under harsh operating conditions. This lubricant pack combined with stainless steel bearing components and synthetic rubber seals, provides a significant increase in bearing life in these applications. Stainless steel single row, deep groove ball bearings packed with W64F solid lubricant are available from stock in five sizes, as shown in the table below. In addition to the suffix ST to denote stainless steel, a descriptive suffix -W64F is included to distinguish them from standard stainless steel bearings. Other sizes can be furnished on special order. For equivalent load and life calculations see page 54 and 55 in the MRC Engineering Handbook. Technical Data Maximum Operating Temperatures The temperature limits, measured on the bearing outside diameter are: Maximum continuous: 80 F (82 C) Maximum intermittent: 200 F (9 C) Load Ratings Load ratings for bearings lubricated with W64F solid lubricant are the same as for standard bearings. Speed Limits The speed limit Ndm, is dependent on the bearing bore and outside diameters, and RPM, in the following relationship: Nd m =RPM x (Bore + O.D.) 2 (bore, OD in mm) For double sealed or shielded, single row, deep groove, stainless steel ball bearings, the limiting value of Ndm is 240,000. It is important to note that as ambient or externally produced temperatures increase, the maximum operating speed may have to be reduced, to keep the bearing operating temperature within the maximum operating limit. As with most bearing lubricants, reducing bearing temperature adds to the capability of W64F.

Note: For composite pillow block and flanged housings, a thick, flat stainless steel washer should always be installed between the bolt head and mounting base to properly distribute the clamping force. Step 4 ZMaRC Inserts Before the set screws are tightened, reinspect the position to make sure the housing did not shift when the base bolts were tightened. Tighten each set screw alternately with the proper hex head socket wrench until they stop turning and the hex head socket wrench starts to spring. Reference Table B for maximum recommended set screw tightening torque values and wrench dimensions. These values should not be exceeded. Step 4 Stainless Steel Inserts Before the set screws are tightened, reinspect the position to make sure the housing did not shift when the base bolts were tightened. Remove the set screws and apply a bonding agent to the set screw s threads such as LocTite and insert the set screws back into the inner ring. Tighten each set screw alternately with the proper hex head socket wrench until they stop turning and the hex head socket wrench starts to spring. Reference Table B for maximum recommended set screw tightening torque values and wrench dimensions. These values should not be exceeded. Step Step 2 Step Step 4 40

Then swivel the bearing into position using a piece of tubing through the bore. If the housing has a relubrication fitting, the set screw side of the bearing should be matched to the side of the housing with the insert slots. In order to ensure that the relubrication fitting and lubrication holes line up, the initial misalignment should not exceed 5 degrees. Visit to download CAD drawings of MRC bearings 4
