Product Overview

The Bosch Rexroth Bearing Shell Pair is a genuine OEM high-precision internal cradle bearing set engineered for variable displacement axial piston units, such as the Rexroth A4VG71 (Series 32) pump. This matched half-shell bearing pair features a specialized stepped edge profile ("W. STEP") to ensure stable seating within the pump housing cradle. It provides a smooth, low-friction surface for the swashplate to glide upon when regulating fluid output. Manufactured from a premium, wear-resistant anti-friction alloy, it absorbs heavy dynamic forces, prevents mechanical galling, and ensures predictable, responsive displacement control under intense system pressures.
