XR Extra Rigid Bearings The Extra Rigid XR Ball Bushing bearing is designed to maximize load carrying capacity while minimizing deflection. The increased load capacity and/or travel life is provided by the bearing's advanced plate design. Each ball conforming bearing plate is precision ground, providing smooth and virtually friction free linear movement. The XR bearing plates have been positioned to maximize load capacity in both pull-off and down loading conditions. XR Extra Rigid Ball Bushing Highlights: • Non self-aligning ball conforming bearing plates offer three times the rigidity of conventional linear bearings • Rigid ductile iron pillow blocks for maximized stiffness • Wear resistant, low-friction polymer housing reduces inertia and operating noise levels
