Spherical Self Lubricating High Misalignment

Spherical bearings are self aligning bearings used extensively on the driven parts in the aerospace, automobiles, railways and industrial machines. We offer distinctive products that will fit your needs, such as PTFE bearings that have a self-lubricating function, or metal to metal bearings that perform well under static and high load environment.
Please consult with our sales unit when designing for special purposes.

Feature of a Product

・Self lubricating
The PTFE lining is bonded to the inner diameter of the race. The PTFE Liner acts as a lubricant and therefore no other lubrication is necessary. Thus they are eminently suitable to apply where re-lubrication is impractical or impossible. More over, as they don't require any lubrication, they are effective to lower the maintenance cost. They perform well under slow fluctuation velocity and oscillation load. Therefore PTFE type can induce the difficulties of metal/metal type such as high friction, seizure, fatigue destruction and fretting on the fluctuating surface.
