Composite guide rings

Composite guide rings have the function of preventing mechanical contact between pistons, bores and rods. Therefore, they have to absorb all transverse forces that occur.


The function of guide rings (also called hydraulic wear rings, wear bands, or bearings) is to guide the piston and piston rod of a hydraulic cylinder, absorbing transverse forces. At the same time, it prevents metal-to-metal contact, optimizing the performance of the sealing system. However, additional functionality includes limiting side-loading and preventing pressure spikes. The cross sectional geometry of the wear ring is of critical importance and must be matched to the sealing application.
