Product Overview

The OEM Bosch Rexroth R902600839 Rod Guidance Ring is a genuine factory replacement wear ring engineered to guide rods and pistons within heavy-duty hydraulic cylinders, pumps, and valve control actuators. Measuring exactly 80mm inside diameter, 85mm outside diameter, and 14.8mm width, this high-precision guidance ring absorbs massive lateral forces and prevents metal-to-metal contact between moving internal parts. Fabricated from an advanced, low-friction composite material (indicated by the premium C380 compound code), it guarantees uniform load distribution, smooth linear stick-slip-free motion, and exceptional wear resistance under intense mechanical vibrations and high-pressure hydraulic operating cycles.
