Abstract
A sleeve assembly for sanding a piston rod of a hydraulic cylinder or the like comprises a rigid annular outer member, a resilient annular intermediate member adhesively secured to the inner surface of the outer member, and an abrasive annular inner member adhesively secured to the inner surface of the intermediate member for interference contact with the piston rod. The sections of the annular members each have complementary nonaxial end configurations to prevent scoring of the piston rod during axial movement. Clamp means releasably engages the members around the piston rod. In some embodiments, bracket or angle bar means are utilized to releasably secure the sleeve assembly to structure at the end of the cylinder. In another embodiment, the sleeve assembly is releasably clamped directly around the end of the hydraulic cylinder.
