Rotor Clip DSH-16ST PDB100 External Retaining Ring 16mm

Product Description

The ROTOR CLIP DSH-16ST PDB100 is a DIN 471 external retaining ring designed to secure components on a 16 mm shaft. Manufactured from 1060-1090 spring steel with a phosphate and oil finish, this ring provides reliable axial retention in rotating and static assemblies. It seats in a precision-machined groove with a 15.2 mm groove diameter and a 1.00 mm ring thickness. The hardness rating of 63-69.5 HR30N ensures resistance to deformation under load. Licensed tradespeople and assembly technicians working with metric shaft assemblies will find this ring a direct-fit solution for standard DIN 471 applications.

This external retaining ring is suited for use in mechanical assemblies where a metric 16 mm shaft is present and axial retention of gears, bearings, pulleys, or similar components is required. The DIN 471 standard makes it compatible with metric groove specifications common in industrial equipment, HVAC blower assemblies, pump shafts, and other rotating machinery. Sold in minimum order quantities of 100 units, this ring is appropriate for both service replacement and production-level use.

Compatibility

Designed as an OEM-style replacement external retaining ring for any assembly calling out a DIN 471 specification on a 16 mm shaft with a 15.2 mm groove diameter.

Installation Notes

Installation requires snap ring pliers sized for external retaining rings. Ensure the shaft groove is free of burrs and debris before seating the ring. De-energize and lock out any equipment before servicing shaft assemblies. Do not over-expand the ring during installation, as spring steel rings can crack if spread beyond their rated free diameter tolerance.
