3 oller earing Pillow locks M76 inear earings Designed to overcome the limitations of linear bearings with multiple re-circulating ball circuits and to provide a product with trouble free operation, M76 oller earing Pillow locks provide the following advantages: DV: DJUM - M76 oller earing Pillow locks constructed with an adjustable eccentric stud feature to allow easy radial clearance adjustment. he clearance is set at the factory for optimum shaft clearance for M76 earings 60 shaft tolerance. his shaft clearance can easily be adjusted to provide for very loose to preload conditions. M M76 ingle oller earing Pillow locks are self aligning due to the unique design. his oller earing Pillow lock has a higher tolerance to shaft deflection than the recirculating ball pillow block. n most applications, the double and twin models also either match or exceed the tolerances for misalignment offered by recirculating ball pillow block. M76 oller earing Pillow locks are constructed with an aluminum body. he exposed surfaces of the rollers have a black oxide finish to resist corrosion. pecial rollers of stainless steel or chrome plated are available in some sizes. PD he design of them76 oller earing Pillow lock incorporates a larger rolling diameter than ball bushing pillow blocks. his allows operation at significantly higher speeds and acceleration than the equivalent size recirculating ball pillow blocks. Y M76 oller earing Pillow locks mounting hole locations and shaft center to mounting surface dimensions are identical to all of the other popular linear pillow blocks of the same size. UD ach roller component can be easily replaced without replacing the entire pillow block. or information regarding rebuild kits see page 5. W M76 oller earing Pillow lock s have a very low rolling dynamic coefficient of friction (00 on average) and a very low resistance to motion. Unlike ball bushing pillow blocks which require shaft seals for proper operation, the M76 oller earing Pillow lock s have individually sealed rollers, and does not require shaft seals that generate resistance to motion. U ach roller bearing is individually lubricated with a lithium base grease and sealed. his minimizes the need for periodic lubrication. ithium base grease is preferred in this type of application because it has the ability to stand up under churning action in a confined space. his type of grease is also designed to run on an oiled shaft for optimum travel life. he bearings can run on a dry shaft, but a shorter travel life will result. P MPU he operating temperature of the M76 oller earing Pillow lock is determined by the temperature limit of the lubrication and seals. he normal operating temperature range is 60 to 25 PM hem76 oller earing Pillow lock s feature a loating ption will permit shafts to be out of parallelism. he M76 oller earing Pillow lock is the only linear motion pillow block with this patented option to compensate for non-parallel shafts. J K D P Unlike recirculating ball pillow blocks which create a point contact between the ball and the shaft, the main roller outer race of the M76 oller earing Pillow lock has a concave groove to match the shaft diameter. his creates a line contact versus a point contact. he point contact associated with recirculating ball bushings generates very high stress, is prone to shaft grooving, and premature shaft failure. or applications that exceed normal bearing requirements or for applications that are unusual or abnormal, please contact the factory

4 J ail oading Data J Jet ail ail oller locks offer smooth, very quiet and solid linear motion. heir design dictates that the load fall on the top rollers which have a center radius which meets the crown of the shaft. hus a straight and uniform compressive load is ideal for their construction. hey are not designed for side loading - where the side rollers are being loaded. or are they to be inverted (upside down/ceiling mounted), again loading the side rollers. ince the cam follower is a needle bearing with an inner and outer race, we do not want a load scenario where the inner and outer races are put in shear. his will cause the races to separate and fail prematurely.

9 oller earing Pillow lock ptions P P When pillow blocks run in an environment where chips or sludge accumulate on the top of the linear shaft, select the scraper option. he scraper is made from spring steel tempered phosphor bronze and conforms to the shaft diameter. scraper is mounted to each end of the bearing assembly which cleans the top of the shaft in either direction. M76 inear earings he scraper option requires a specially machined pillow block, and cannot be added as a retrofit to a pillow block originally ordered without this option. his option may temporarily increase resistance to motion, but after a short break-in period this increase will be insignificant. J o order the scraper option, add the suffix - after the pillow block model number. or example P-16-P- P he floating option is available on all models of the oller earing Pillow lock.. his patented option is the only product on the market that provides a real solution for shafting that is out of parallel.his option is beneficial when trying to align long shafts, or when the system does not meet the required parallelism. loating pillow blocks should be used in conjunction with standard pillow blocks which ride on one shaft and the floating on the other shaft. n the top of each floating pillow block are two grooves which should be filled with the special grease that is supplied. When installing, care should be taken not to over tighten the mounting screws or bolts, causing the floating bushings to bind. o order floating pillow blocks add the prefix to the single, double, or twin bearing. or example P-16-P K Pillow lock ize 8,10, ,2 32 8,6 loating Movement 1/16" 3/32" 1/8" 5/32" 3/16"

10 P P he M76 oller earing Pillow lock rollers are lubricated and sealed, but in some applications it is desired to re-grease the main support roller. he top grease option can help achieve full bearing life in applications that reduce or contaminant the grease inside the roller. uch onditions may exist in applications where solvents or contaminants leach out the grease through the vents in the seals, or where contaminants are so fine or extreme that they must be purged out of the roller with fresh grease. he top grease option is also recommended when high speeds or extreme temperatures are present. P P D o order the top grease option. dd the suffix - after the pillow block model number. or xample P-2-P-. vailable in 1-1/ Pillow locks and larger. PW K UD K ebuild kits for M76 oller earing Pillow locks are available with all the required parts to completely rebuild each unit. or single units order one kit. or Double or wins, order two kits. When ordering a rebuild kit, you must advise the factory of the run number that is stamped on the end face of the pillow block. his run number assures you will get the correct parts needed to rebuild your unit. or example: #K his would be one kit for a 1 pillow block with a run number of 107. ach kit contains one fixed side roller, one eccentric side roller, one top roller, one top roller axle and one set screw. ndividual Parts are also available. owever, it is recommended when a pillow block is removed for parts replacement, all components should be replaced before the pillow block is re-installed.

18 M76 inear Motion M-arbell s modern facility in ast ongmeadow Massachusetts ome of the MUM inear/otary earing M-arbell is the combination of two internationally prominent manufacturers of sleeve bearings: J.. arbell ssociates ounded in 1938, J.. arbell ssociates was one of the first exclusive regional distributors for hrysler s oil impregnated bronze bearing line - a technological innovation at the time. ver the past 60 years, arbell has engineered this material into every product conceivable from sewing machines to jet engines. oday, arbell supplies engineering expertise, standard products and machined specials to companies throughout the world. ounded in 1976, M76 found its genesis in combating traditional problems which plagued linear ball bushings: mechanical cage/ball failure and shaft brinelling or grooving. M76 s response was their ceramic coated, direct drop-in replacement linear bearing line which was hailed as a genuine innovation by engineers and maintenance personnel alike. M76 s latest product innovation is its MUM elf ubricating inear/otary bearing line. his line offers outstanding load carrying capability coupled with a remarkably low coefficient of friction. dd these two companies together and you get a singular wealth of sleeve bearing experience. Moreover, you can be confident that our recommendations/products are solid, proven and the best your company can purchase
