Rotor Clip DSH-45ST Pd External Retaining Ring 45mm

Product Description

The ROTOR CLIP DSH-45ST PD is a DIN 471 external retaining ring designed to secure components on shafts in a wide range of mechanical assemblies. Manufactured from DIN 17221 and 17223 spring steel with a phosphate finish, this ring provides reliable axial retention on a 45 mm shaft diameter with a groove diameter of 42.5 mm. The phosphate coating offers a base level of corrosion resistance and surface lubricity suited to industrial and OEM applications. Machinists, maintenance technicians, and assembly professionals install this ring type using standard snap-ring pliers. It ships in a package quantity of five.

This external retaining ring is suited for use in rotating shaft assemblies, gearboxes, motors, pumps, and general mechanical equipment where metric DIN 471 hardware is specified. Its metric sizing and DIN 471 compliance make it a direct fit for European-standard equipment as well as domestic machinery designed to metric tolerances. The phosphate finish is appropriate for indoor or protected environments. Applications include automotive, industrial machinery, hydraulic assemblies, and any system requiring a low-profile external shaft retainer at the 45 mm nominal size.

Key Features

• DIN 471 compliant external retaining ring for 45 mm shaft diameter
• Spring steel construction per DIN 17221 and 17223 material grades for consistent snap force and fatigue resistance
• Phosphate finish provides surface lubricity and mild corrosion protection
• Groove diameter of 42.5 mm with a tolerance of -0.25 mm for precise axial retention
• Ring thickness of 1.75 mm with a tolerance of -0.06 mm
• ISO 13485:2015 standards compliance noted for quality management applicability

Compatibility

Designed as an OEM-style external retaining ring for metric shaft assemblies requiring DIN 471 hardware at a 45 mm nominal shaft diameter.

Installation Notes

Installation and removal require external snap-ring pliers sized for DIN 471 rings. De-energize, depressurize, or lock out the equipment fully before servicing any shaft assembly. Confirm groove dimensions match the ring specifications before installation to avoid improper seating. Do not reuse a retaining ring that has been removed, as spring steel rings may lose retention force after deflection.
