Patented Thomson Lube for Life self-lubricating linear ball bushing® bearing pillow blocks for continuous lubrication for the life of the linear bearing, resulting in maintenance-free operation.
Thomson Lube for Life cartridges provide continuous, maintenance-free lubrication. Self-lubricating cartridges are pressed into each end of the pillow block housing. Each cartridge contains a microporous polymer that diffuses oil when the bearing is in motion. The oil migrates through capillary action to the shaft in contact with the polymer. The polymer also acts as a sponge and reabsorbs the oil during motion. This prevents excessive buildup of the lubricant on the shaft, and minimizes dripping, which is common when applying oil manually. The Lube for Life polymer is under constant pressure against the shafting, ensuring a film of lubricant between the ball bearings and inner face.
Customers who require maintenance-free operation discover cost savings with the Lube for Life cartridges due to their elimination of expensive lubrication systems. The cartridges are also available in a retrofit kit and can be added to existing non self-lubricating pillow block assemblies.
