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.
