Rotor Clip DSH-30ST Pd External Retaining Ring 30mm Spring Steel

Product Description

The ROTOR CLIP DSH-30ST PD is an external retaining ring designed for 30 mm diameter shafts. Made from spring steel with a phosphate finish, it provides reliable axial retention of components on shafts in mechanical assemblies. The ring seats in a precision groove and holds position under load without fasteners or threading. With a groove diameter of 28.6 decimal inches and a ring thickness of 1.5 inches, this ring meets DIN 471 dimensional standards. It is suited for equipment maintenance, mechanical assembly, and industrial applications where consistent, repeatable fastening is required. Licensed trades and mechanical assemblers install these rings using standard retaining ring pliers.

This external retaining ring is used in shaft-mounted assemblies across a wide range of industrial and mechanical equipment. Typical applications include electric motors, pumps, gearboxes, and actuators where axial component retention is needed without threaded fasteners. The phosphate finish provides corrosion resistance suitable for standard indoor mechanical environments. This package contains 25 rings, making it appropriate for production assembly work or service shops maintaining an inventory of common hardware sizes. The metric measurement system and DIN 471 compliance make this ring compatible with equipment manufactured to European and international standards.

Installation Notes

External retaining rings of this type are installed and removed by qualified mechanical technicians using external retaining ring pliers sized for the ring diameter. De-energize and lockout all equipment before servicing any shaft-mounted assembly. Inspect the shaft groove for wear or damage before seating a new ring. Confirm groove diameter and depth match the ring specifications before installation to prevent ring displacement under load.
