Self-lubricating bearing is a special kind of bearing that keeps the bearings running normally by means of transfer lubrication that comes from the retainer.

Self-lubricating bearings are divided into composite self-lubricating bearings, solid embedded self-lubricating bearings, bimetal self-lubricating bearings and special self-lubricating bearings. Self-lubricating bearings are selected according to different uses and mines. It can also prevent foreign substances from invading the interior of the bearing, and prevent the bearing from rusting and stripping. Self-lubricating bearing has: good wear resistance, small friction coefficient, long service life; It can reduce vibration, reduce noise, prevent pollution and improve working conditions. Thin-wall structure and other advantages.

Working principle

The composite material used in the Mosaic self-lubricating bearing is a new type of solid lubrication material with extreme pressure resistance, which is composed of a metal substrate and a solid lubricant paste in the hole or groove embedded in the substrate. The metal substrate bears most of the load during the friction process. Through friction, the solid lubricant in the hole or groove transfers or reversely transfers to the friction surface, forming a solid transfer film with good lubrication, firm adhesion and uniform coverage on the friction surface, greatly reducing friction and wear. With the progress of friction, the embedded solid lubricant is continuously provided to the friction surface to ensure good lubrication of the friction pair during long-term operation.
