Our composite spherical bearing is made of synthetic fiber, reinforced polyester resin and other self-lubricating micro powers. It can be a direct replacement for conventional steel spherical bearings, they have virtually no electro-chemical corrosion in seawater or other aqueous solutions, which means that the composite bearings will not rust. This makes them ideal for marine and hydropower applications. Their superior elasticity over metal bearings means they can resist edge-loading and misalignment even under extreme heavy loads.

Product application
Spherical bearing is generally used for low speed pendular movement (i.e. angular motion), because the sliding surface is spherical shaped, it can also be used for tilting motion (i.e. aligning movement) in a certain angle range. Even the non concentricity between the supporting shaft and the shaft shell hole is bigger, it can work normally.
