MOLDED WEAR GUIDE
Wear guides are thermoplastic bearings that are resilient and wear-resistant. They're designed to go inside hydraulic applications in order to support, guide or reduce the friction between the cylindar body and rod. Wear guides are exceptionally important where heavy side loadings are unavoidable. For example, over time, a heavy side loading can cause normal rod bearings to form an oval shape. The oval shape could then cause poor seal performance as the clearance between the rod seal and rod shaft becomes larger due to wear. This distortion can then cause excessive fluid leakage, rod seal deformation, seal extrusion, and eventually, seal blowout.
