MOLDED WEAR GUIDE

Wear guides are resilient, wear-resistant, thermoplastic bearings designed to go inside hydraulic applications to support, guide or reduce the friction between the rod and the cylinder body. These wear guides are especially important in applications where heavy side loadings are unavoidable. For example, a heavy side loading over time can cause normal rod bearings to become oval shaped. This oval shaped rod bearing could then cause poor seal performance as the clearance between the rod shaft and the rod seal becomes larger due to wear.  This distortion can lead to excessive fluid leakage, deformation of the rod seals, seal extrusion, and eventually seal blowout.
