8 Models and Features SPHERICA ROER BEARING UNITS 2 - Bolt Base Type SN Pillow Block Units ZS2SN is patented Z OCK spherical roller bearing unit with SN style housing for the replacement of SN pluer blocks. XS2SN has the same housing dimensions as the above styles but utilizes the patented Bullet Point setscrews at 20 degrees apart to hold shafting firmly in place. ZS2SN XS2SN 2 - Bolt Base Pillow Block Units ZS2P is a two-bolt pillow block unit with a Z OCK locking system. This unit is equivalent to many of our competitors SRB style housings. The ends of the housing are milled flat to allow for mounting inside of a fixed frame assembly. ZS2P ZSE2P 4 - Bolt Flange Units XS2P XSE2P ZSE2P is a two-bolt base pillow block unit with Type E mounting dimensions. It has a footprint that can accoodate both a tapered roller unit and a spherical roller unit for most shaft sizes. XS2P and XSE2P have the same housing dimensions as the above styles but utilizes the patented Bullet Point setscrews at 20 degrees apart to hold shafting firmly in place. ZS4F is a four-bolt flange unit with standard spherical roller unit mounting dimensions and a compact footprint for areas with limited space. ZS4F ZSE4F Flange Cartridge Units XS4F XSE4F ZSE4F is a four-bolt flange unit with Type E tapered roller unit mounting dimensions. This makes for easy replacement of Type E units when the features of a spherical roller unit are more desirable. XS4F and XSE4F have the same housing dimensions as the above styles but utilizes the patented Bullet Point setscrews at 20 degrees apart to hold shafting firmly in place. ZS4FC is a flange cartridge unit with pilot mounting dimensions that are the same as medium duty ball bearing units for easy upgrading to a heavier duty series. The threaded withdrawal holes allow for quick and easy dismounting. ZS4FC XS4FC XS4FC has the same housing dimensions as the above styles but utilizes the patented Bullet Point setscrews at 20 degrees apart to hold shafting firmly in place. Take - Up Units ZST is a take-up unit with rail slots that are compatible with many industrial frame sizes. This unit can safely handle high belt tension and heavy shock loads.

34 FYH Spherical Roller Bearing Units Installation Guide PRECAUTIONS Read the entire installation guide prior to beginning. Bearings are precision instruments and they must always be handled carefully to prevent damage. Store bearings in a cool and dry location, and always leave bearings in original packaging until ready for installation. Bearing life calculations should be performed prior to installation to ensure that the selected unit is acceptable for the application. The use of more than two bearings on a single shaft is not recoended. To maximize the life of the bearing avoid mis-alignment and pre-loading by carefully following these instructions. Always lock out the power source and adhere closely to industry safety standards before performing any work on the equipment. PREPARATION The mounting surface and housing base must be clean, flat, and of sufficient thickness to support the weight of the entire assembly without deflecting or breaking. Make sure that the mounting surface is parallel to the plane of the shaft for pillow blocks, and perpendicular to the shaft for flanges and take-up units. FYH mounted bearings can accoodate up to ±2 degrees of mis-alignment, however longer bearing life can be achieved if mis-alignment can be minimized during installation. Check the shaft diameter and make sure that it is within tolerance as indicated in Table. Check that the shaft is straight, clean, and free of burrs or other imperfections. Use emery cloth or a fine file to smooth the surface as necessary. A small amount of lubricant may be applied to both the shaft and the bore of the bearing; however lubricant should not be applied to the areas where the bearing locking mechanism contacts the shaft. Table - Shaft Tolerance Shaft Size () h6 Shaft Speed Greater Than 50% of Max RPM Rating h7 Shaft Speed ess Than 50% of Max RPM Rating Over Incl. Max () Min () Max () Min () INSTAATION. Slide the unit onto the shaft while holding the inner ring of the bearing. Position the unit on the mounting surface so that the plane of the shaft is perpendicular to the face of the housing, and alternately tighten the mounting bolts to the specified torque as shown in Table 2. Make sure to use bolts, washers, and nuts of sufficient strength and grade rating for the application.

35 2. Check the final position of the shaft and alternately tighten the set screws of the non-expansion unit onto the shaft to the specified torque setting as shown in Table. The set screws in the bearing on the opposite side of the shaft should line up with the set screws of the bearing that was installed first (See Table 4, Figure A). Expansion bearings should be installed only after the shaft and adjacent machinery has cooled down to the ambient temperature. After positioning the expansion unit on the shaft slide the insert to the rearmost position within the housing until it seats against the retaining ring. Then slide the insert forward in the housing approximately one thirty-second of an (/2 ) and alternately tighten the set screws onto the shaft to the specified torque setting as shown in Table. Allowable shaft expansion and expansion calculation data can be found in Table 4 and Formula respectively.

Once installed, slowly rotate the bearing by hand to confirm that it turns smoothly and without resistance, vibration, or any other abnormalities. 4. To install Z OCK, tighten the four cap screws on the face of the locking collar with the included Allen wrench evenly. Repeat to draw the collar onto the inner ring. (See Table 5) To disassemble, remove all the black cap screws as well as the two silver cap screws. Screw two black cap screws where the silver cap screws had been. Screw the two black cap screws until the collar disengages.

36 FYH Spherical Roller Bearing Units Installation Guide UBRICATION Proper lubrication practices will greatly extend the life of the bearing. Bearings are factory lubricated with the proper amount and type of lubricant for most general purpose applications as well as many highly demanding operating environments, and except as recoended by FYH, no further lubrication is required upon installation. ubrication tips: The factory standard lubricant is a calcium sulfonate grease. Always use the same type of lubricant to avoid compatibility issues and other potential problems. When adding lubricant do so slowly and while the bearing is rotating until a small amount of lubricant can be seen coming out of the seals. At low speeds (below 200 RPM) it is acceptable to completely fill the bearing with grease. At moderate to high speeds it is not advisable to completely fill the bearing with grease as it could lead to overheating and reduced bearing life. It is generally better to use less lubrication more frequently than more lubricant less often. If the unit will not be operated for an extended period of time extra lubricant should be added to prevent corrosion. If the unit has not been operated for an extended period of time fresh lubricant should be added prior to start-up. If the unit becomes too hot during operation from over-lubrication remove the grease fitting and operate the unit for approximately thirty minutes to allow excess grease to purge. Appropriate lubrication intervals can be determined by referring to Table 6; however experience should largely determine the actual lubrication regimen for a particular application. Consult with an FYH representative for assistance. If a suitable Calcium Sulfonate lubricant is not available for re-lubrication then the following compatible lubricants may also be used: Barium Complex, Calcium Stearate, ithium Complex, Polyurea (Shear Stable) The use of any other type of lubricant should be avoided to prevent compatibility issues with the Calcium Sulfonate grease that is originally supplied. To find the proper lubrication interval in Table 6 obtain the relevant percentage of max allowable RPM by referring to Table 7. Example: XS4 with positive contact seals has a max RPM rating of If the application has an RPM of 600 then the percentage of max RPM is 0% (600/2000 =.0). The amount of grease for replenishment can be found in Table 8. 6

Before bearing installation On the back side of the unit (opposite the housing markings), remove the bearing retaining ring located on the inner diameter of the housing and move it back to the groove on the outer position of the housing. Slide the bearing insert rearward within the housing until it sits against the retaining ring that was just relocated. When ready for installation, slide the insert forward in the housing approximately one thirty-second of an ( /2 ) and alternately tighten the set screws onto the shaft to the specified torque setting as shown in Table. After bearing installation Before performing any work on the bearing, lock out the power source and allow the shaft and adjacent machinery to cool down to ambient temperature. oosen the set screws or other locking mechanism to allow the shaft to move freely within the bore then follow the same procedures explained in the Before bearing installation section. 7
