4 Models and Features SPERIC ROER ERIG UITS - olt ase Type S Pillow lock Units - olt ase Pillow lock Units ZSS - olt ase Pillow lock Units XSS ZSS is patented Z OCK spherical roller bearing unit with S style housing for the replacement of S pluer blocks. XSS has the same housing dimensions as the above styles but utilizes the patented ullet Point setscrews at degrees apart to hold shafting firmly in place. ZSP XSP ZSP is a four-bolt base pillow block unit with standard spherical roller bearing mounting dimensions. Four mounting bolt-holes create a firm and secure fit to the mounting surface. The ends of the housing are flat to allow for mounting inside of a fixed frame assembly. XSP has the same housing dimensions as the above styles but utilizes the patented ullet Point setscrews at degrees apart to hold shafting firmly in place. ZSP ZSEP - olt Flange Units ZSF ZSEF Flange Cartridge Units ZSFC XSP XSEP XSF XSEF XSFC ZSP is a two-bolt pillow block unit with a Z OCK locking system. This unit is equivalent to many of our competitors SR style housings. The ends of the housing are milled flat to allow for mounting inside of a fixed frame assembly. ZSEP 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. XSP and XSEP have the same housing dimensions as the above styles but utilizes the patented ullet Point setscrews at degrees apart to hold shafting firmly in place. ZSF is a four-bolt flange unit with standard spherical roller unit mounting dimensions and a compact footprint for areas with limited space. ZSEF 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. XSF and XSEF have the same housing dimensions as the above styles but utilizes the patented ullet Point setscrews at degrees apart to hold shafting firmly in place. ZSFC 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. XSFC has the same housing dimensions as the above styles but utilizes the patented ullet Point setscrews at degrees apart to hold shafting firmly in place. - olt ase Pillow lock Units (Double Collar) ZDSP XDSP SPERIC ROER ERIG ISERTS Spherical Roller earing Inserts (Single Collar) ZS XS Spherical Roller earing Inserts (Double Collar) ZDSP is the same as the ZSP but utilizes a double lock. This insert has patented Z OCK locking mechanism on both the front and back of the inner ring. This additional locking mechanism is helpful in applications where the bearing experiences some thrust loads on the inner ring that could cause a single locking unit to slip. XDSP has the same housing dimensions as the above styles but utilizes the patented ullet Point setscrews at degrees apart to hold shafting firmly in place. ZS is a Z OCK concentric locking insert that utilizes a tapered collar that allows for fast mounting while avoiding damage to shafting that a setscrew unit can cause. The tapered collar keeps the 00% true concentric holding power and does not remove any clearance in the insert by over tightening like the adaptor sleeve locking system can. The unit is tightened down using a hex wrench on the cap screws in a star pattern. The insert can be uninstalled by removing all cap screws and using two of them in the withdrawal holes to disengage the collar. XS is a setscrew locking insert that utilizes the patented ullet Point setscrews at degrees apart to hold shafting firmly in place. This is the most economical type of SR insert and can be utilized in a wide variety of industrial and agricultural applications. ZDS is the same as the ZS above but utilizes a double lock. This insert has a concentric tapered collar on both the front and back of the inner ring. This additional locking mechanism is helpful in applications where a bearing experiences some thrust loads on the inner ring that could cause a single locking unit to slip. 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. XST has the same housing dimensions as the above styles but utilizes the patented ullet Point setscrews at degrees apart to hold shafting firmly in place. ZDS XDS XDS is the same as the XS above but utilizes a double lock. This insert has a setscrew locking mechanism on both the front and back of the inner ring. This additional locking mechanism is helpful in applications where the bearing experiences some thrust loads on the inner ring that could cause a single locking unit to slip. ZST XST 6

16 FY Spherical Roller earing Units Installation Guide PRECUTIOS Read the entire installation guide prior to beginning. earings 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. earing 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. lways lock out the power source and adhere closely to industry safety standards before performing any work on the equipment. PREPRTIO 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. FY mounted bearings can accoodate up to ± 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. 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. Shaft Size () h6 Table - Shaft Tolerance Shaft Speed Greater Than 0% of Max RPM Rating h Shaft Speed ess Than 0% of Max RPM Rating Over Incl. Max () Min () Max () Min (). 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, Figure ). Expansion bearings should be installed only after the shaft and adjacent machinery has cooled down to the ambient temperature. fter 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 inch ( ) and alternately tighten the set screws onto the shaft to the specified torque setting as shown in Table. llowable shaft expansion and expansion calculation data can be found in Table and Formula respectively. = T D Table - Set Screw Tightening Torque (recoended) Set Screw Tightening Torque Size Code Set Screw Size m in-lbf ft-lbf XS08-XS09 /6-8UF. 8 XS0-XS -UF. 6 9 XS-XS -UF Size Code Table - Quantity of Total Movement Quantity of Total Movement XS08-XS0 ZS08-ZS0 XS-XS ZS-ZS 6 Formula inear Shaft Expansion Figure Set Screws ined Up in oth earings : Expansion of shaft () : inear expansion coefficient of shaft for ordinary steel (. x 0 6 ) T : Temperature increase (ºC) D : Installation distance between bearing units () llowable shaft expansion: /6 max inch ISTTIO. Once installed, slowly rotate the bearing by hand to confirm that it turns smoothly and without resistance, vibration, or any other abnormalities.. 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. Make sure to use bolts, washers, and nuts of sufficient strength and grade rating for the application.

17 FY Spherical Roller earing Units Installation Guide URICTIO Proper lubrication practices will greatly extend the life of the bearing. earings 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 FY, no further lubrication is required upon installation. ubrication tips: The factory standard lubricant is a calcium sulfonate grease. lways 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. t low speeds (below 0 RPM) it is acceptable to completely fill the bearing with grease. t 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. ppropriate 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 FY representative for assistance. If a suitable Calcium Sulfonate lubricant is not available for re-lubrication then the following compatible lubricants may also be used: arium 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. Example: XS with positive contact seals has a max RPM rating of 00. If the application has an RPM of 0 then the percentage of max RPM is 0% (0000 =.0). The amount of grease for replenishment can be found in Table 8.
