Product Overview

The Bosch Rexroth Shim Ring is a genuine OEM high-precision internal spacing element designed for variable displacement axial piston units. Built to a precisely calibrated thickness of 1.20 mm under the 21522.2101 model profile, this shim provides the exact mechanical clearance or spring preload required inside the pump's internal rotating group. Precision-ground from hardened, wear-resistant alloy steel, it eliminates micro-axial play, evenly balances mechanical loads, and shields internal components from erratic friction and premature mechanical wear.
