Rotor Clip DSH-20SS External Snap Ring 20mm Shaft 420 Steel

Product Description

The ROTOR CLIP DSH-20SS is an external snap retaining ring designed for use on 20 mm diameter shafts with a groove diameter of 19 mm. Manufactured from 420-grade steel with a phosphate and oil finish, this ring provides reliable axial retention of components on shafts and housings. It meets DIN 471 and SAE 1060-1090 fastener standards and conforms to ISO 13485:2015. With a hardness rating of 44-51 HRC, the ring resists deformation under load. Mechanical assemblers and maintenance technicians install this ring in both production and field service applications where a removable, external retention solution is needed.

This retaining ring is suited for metric shaft assemblies in industrial, mechanical, and trade equipment applications. The external snap design seats into a machined groove on the shaft OD, locking axial position without threads or adhesive. It is a standard metric component used across a broad range of mechanical assembly scenarios including motors, gearboxes, and rotating assemblies. Supplied in a package quantity of two units per order.

Compatibility

Designed for use on 20 mm diameter shafts with a machined external groove per DIN 471 specifications. Suitable as a standard metric external snap ring replacement in any application requiring DIN 471-compliant retention hardware.

Installation Notes

Installation requires external snap ring pliers appropriate for the ring diameter. Power down and de-energize any associated equipment before disassembly or ring installation. Ensure the shaft groove dimensions match the ring specifications before seating the ring to avoid improper retention. Follow applicable machinery safety standards and equipment manufacturer procedures during installation.
