Bearings • Self-Lubricating Bearings

Featuring a lubricant contained within the bearing walls, self-lubricating plain bearings are used in applications where excessive friction is a concern. Able to operate under extreme hot and cold temperatures, self-lubricating bearings have a high load capacity and can be used with rotational, oscillatory, and axial sliding motions. Types of self-lubricating bearings include a plastic bearing, which features lubricant molded into the bearing. A sintered metal bearing, which has porous walls that draw oil in via capillary action, is also a type of self-lubricating bearing. Other self-lubricating bearing types include oilite bearings.

  • National Precision Bearing

    National Precision Bearing offers self lubricating and pre-lubricated bearings. Their "NU Series" of self lubricating bearings are used where excessive friction is found. They have a high load capacity and can operate at -328 to 536 degrees F. The "NX Series" of pre-lubricated bearings are used during low friction applications and can also carry high load capacities. These bushings can operate for long periods with only a small amount of lubrication. Thrust washers, ball, spherical plain and needle roller bearings are also available.
