The spherical ball joint bearing combines the wear resistance of the copper alloy (ZCuZn24Al6) and the self-lubricating properties of the solid lubricant, so that it does not require oil maintenance during use.
The spherical ball joint bearing seat base material is copper alloy, the spherical surface is inlaid with solid lubricant; the shaft material is bearing steel, quenched, the spherical surface is hard chrome plated and polished. It has high bearing capacity, self-lubricating, impact resistance, wear resistance, high temperature resistance, self-aligning, low friction, etc. It is suitable for bearing axial load or radial and axial combined load in one direction (the radial load) The mechanical structure must be no more than 0.5 times the axial load value.
It uses a self-lubricating bearing material with a low coefficient of friction as a sliding friction pair and requires no maintenance during operation. It is suitable for applications where the bearing has a long service life without maintenance or working conditions (such as insufficient lubrication or no lubrication at all) does not allow the use of steel-to-steel bearings. This kind of self-lubricating bearing is mainly used for constant heavy load. The outer ring is made of steel base heat treatment, and the inner ring is made of high-strength copper alloy and embedded with solid lubricant.
