We are aimed to try our utmost to provide our customers with excellent Piston Guide Rings, Piston Wear Rings, PTFE Wear Strips and satisfied services more than they desire. We are committed to handle the relationship between quality and speed of development in a balanced manner, which makes the enhancement of our market operation ability and economic efficiency. We integrate the advanced management concepts, and take technological innovation as the breakthrough of transformation and upgrading.
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.
