Product Overview

The OEM Bosch Rexroth R909083403 Retaining Ring is a genuine factory replacement internal snap ring designed to securely position and retain mechanical components axially inside housing bores. Precision-manufactured to strict DIN 472 standards, this heavy-duty internal circlip is engineered for a 45mm nominal bore diameter and features a thickness of 1.75mm, fitting perfectly into machined housing grooves to resist high axial thrust forces. Fabricated from premium-grade heat-treated spring steel, it provides exceptional radial expansion grip and robust structural retention, ensuring critical internal components like bearings, shaft seals, or rotating group elements remain firmly locked in place under continuous operational vibrations and extreme hydraulic pressures.
