Rotor Clip DSH-18SG External Retaining Ring 18mm Shaft

Product Description

The ROTOR CLIP DSH-18SG is a metric external retaining ring designed for 18 mm shaft diameters with a 17 mm groove diameter. Manufactured from 420 stainless steel with a phosphate finish, this ring provides corrosion resistance and dimensional stability in demanding mechanical assemblies. It meets DIN 471 and ISO 13485:2015 standards, making it suitable for precision applications where verified fastener compliance is required. With a ring thickness of 1.20 mm and a groove width of 1.30 mm, the DSH-18SG delivers a secure axial retention solution for rotating or stationary shaft components. Licensed trades and mechanical assemblers install these rings in equipment maintenance, pump repair, and drive system service.

The DSH-18SG is used in industrial and commercial mechanical applications where external shaft retention is needed on 18 mm diameter shafts. Typical installation scenarios include gearboxes, pump assemblies, electric motor shafts, and similar rotating equipment requiring reliable component positioning. This ring is sized to metric standards and is appropriate for any application specifying DIN 471 external retaining rings at the 18 mm nominal shaft size.

Key Features

• Phosphate finish for added surface protection and reduced galling during installation
• Meets DIN 471 and ISO 13485:2015 fastener standards for verified dimensional compliance
• Ring thickness of 1.20 mm and groove width of 1.30 mm for precise axial retention
• Metric dimensioning throughout for compatibility with metric shaft and housing designs

Compatibility

Designed as an OEM-style external retaining ring for 18 mm metric shafts conforming to DIN 471 groove geometry requirements.

Installation Notes

Installation requires external retaining ring pliers sized for the DSH-18SG free diameter of 16.50 mm. De-energize and lock out all equipment before servicing any shaft assembly. Ensure the groove is free of burrs and debris before seating the ring to achieve full groove engagement. Refer to applicable machinery safety codes and the equipment manufacturer service documentation for torque and reassembly requirements.
