When lubrication breaks down, it doesn't matter how robust the bearing is-especially in lighter load, long-travel applications where extended life is desired. These new self-lubricating linear bearing pillow blocks use an oil-saturated polymer with "sponge-like" behavior. A wire spring maintains constant contact, depositing just the right amount of lubricant on the shaft for given temperature and pressure conditions as the bearing moves. A double-lip nitrile seal keeps the lubrication within the custom metal housing, and helps prevent contamination.

Available as an accessory for existing applications with .50-, .75-, and 1-inch shaft sizes, the kits eliminate the costly reservoirs, controllers or switches, and plumbing associated with more complicated lubrication systems.
