Roller Pillow Block Accessories
Top Grease Option Roller Pillow Block rollers are lubricated and sealed. In some applications it is desired to re-grease the main support roller. The top grease option can help achieve full bearing life in applications that reduce or contaminate the grease of the roller. Such conditions 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 they must be purged out of the roller with fresh grease. The top grease option is also recommended when high speeds or high temperatures are present. The top grease option is available on pillow blocks that are 1-1/4" or larger. To order, add the suffix, “TG” after the pillow block model number.
Note: Shock, vibration, and moments may affect the life of the pillow block.
Floating Option The only product on the market that addresses the non-parallel shafting problem is a Roller Pillow Block with the floating option. Also useful when trying to align long shafts, floating Roller Pillow Blocks should be used on one shaft with the standard pillow block on the other. Special grease is included for the grooves on top of each floating pillow block.

During installation do not over-tighten the mounting bushings as this will cause them to bind.
To order, add the prefix, “F-“ to the single, double, or twin Roller Pillow Block number.
Scraper Option Reduce the amount of dirt accumulation that lands on the top of the Roller Pillow Block shaft with the scraper option. Available only on specially machined pillow blocks, the scraper is mounted to each end of the bearing assembly to clean the shaft in either direction. Made from spring-tempered beryllium copper that conforms to the shaft diameter, the scraper will perform successfully after a short break in period. Scraper model is not available as a retrofit. To order this option, add the suffix “-S” after the pillow block model number.
