Rotor Clip DSH-5ST Pd External Retaining Ring 5 Mm

Product Description

The ROTOR CLIP DSH-5ST PD is a DIN 471 external retaining ring designed for use on 5 mm diameter shafts. Manufactured from 1060-1090 grade spring steel with a phosphate and oil finish, this ring seats into a 4.8 mm groove diameter to secure components against axial movement on shafts in assembled mechanical systems. Ring thickness measures 0.60 mm and groove width is 0.70 mm. The phosphate finish provides baseline corrosion resistance and lubricity for installation. Hardness is rated at 63 to 69.5 HR30N, consistent with high-carbon spring steel retaining ring specifications. This is a metric-dimensioned fastener conforming to DIN 471 and SAE 1060-1090 standards.

This external retaining ring is used in light mechanical assemblies, motors, pumps, gearboxes, and similar rotating or stationary shaft applications where a compact, low-profile groove-mounted retainer is required. Its 5 mm nominal shaft size makes it suited for small-shaft assemblies common in HVAC blower motors, pump shafts, and similar trade equipment. Installation is performed by machinists, maintenance technicians, and field service professionals working on sub-assembly components.

Compatibility

Designed as a DIN 471-compliant external retaining ring for 5 mm nominal shaft diameters with a 4.8 mm groove diameter. Verify groove dimensions against shaft specifications before installation.

Installation Notes

External retaining rings of this type are installed and removed using circlip pliers sized for the ring diameter. Power down and de-energize any equipment before accessing shaft assemblies. Ensure the shaft groove is free of burrs and debris before seating the ring. Never reuse a retaining ring that has been over-expanded or shows signs of deformation.
