High-Strength Spring Steel Retaining Ring for Hydraulic Rock Drills Engineered for extreme underground mining conditions, this retaining ring ensures reliable axial retention in high-vibration hydraulic rock drill systems. Constructed from 65Mn spring steel with a nitrided surface treatment (500-700 HV hardness), it withstands continuous dynamic loads while resisting abrasion and corrosion in harsh environments.
Technical Specifications & Design The retaining ring adheres to ISO 8750 standards (45 mm inner diameter, 52 mm outer diameter, 3 mm thickness) for precision fit in hydraulic cylinder assemblies and drill rig components. Its nitrided surface treatment provides superior wear resistance, extending service life by 30% compared to standard electroplated coatings. The 80 N·m threaded connection torque and 250 MPa maximum working pressure make it suitable for heavy-duty hydraulic applications.
