Rotor Clip DSH-18ST Pd External Retaining Ring 18mm

Product Description

The ROTOR CLIP DSH-18ST PD is a metric external retaining ring designed for installation on 18 mm diameter shafts. Manufactured from spring steel with a phosphate finish, this ring seats into a groove machined to 17 mm diameter and provides reliable axial retention of components on shafts in assemblies where removal may be required. At 1.20 mm ring thickness and a free outside diameter of 16.50 mm, it delivers consistent snap engagement across light industrial and mechanical assemblies. Licensed trades and MRO technicians working on metric shaft assemblies install this ring using standard external snap-ring pliers.

This retaining ring is suited for use in metric mechanical assemblies across industrial, HVAC, pump, and motor applications where an external groove retainer is required on an 18 mm shaft. The phosphate finish provides moderate corrosion resistance for indoor and light-duty environments. Conformance to DIN 471 and ISO 13485:2015 standards makes it appropriate for applications with documented quality requirements. Minimum order quantity is 50 pieces; each package contains 1 ring.

Installation Notes

Install and remove using external snap-ring pliers sized for metric rings to avoid distorting the ring or damaging the groove. Verify shaft groove dimensions match the specified 17 mm groove diameter, 1.30 mm groove width, and 0.50 mm groove depth before installation. De-energize and lock out all rotating equipment before servicing any shaft assembly. Do not reuse a ring that has been over-expanded or visibly deformed during removal.
