Rotor Clip DSH-22ST Pd External Retaining Ring 22mm

Product Description

The ROTOR CLIP DSH-22ST PD is a metric external retaining ring designed to seat in a machined groove on a 22 mm shaft, providing positive axial retention of components such as bearings, gears, and collars. Manufactured from spring steel with a phosphate finish, this ring delivers reliable corrosion resistance and consistent spring-back characteristics. With a groove diameter of 21 mm, a ring thickness of 1.20 mm, and a groove width of 1.30 mm, the DSH-22ST PD meets DIN 471 and ISO 13485:2015 standards. Machinists, maintenance technicians, and industrial assembly professionals install these rings in high-volume and service applications where precise axial control is required.

This external retaining ring is suited for metric shaft assemblies in industrial, mechanical, and light-duty machinery applications. It is used wherever a removable, low-profile axial fastener is needed on a 22 mm shaft without threading or welding. Typical install scenarios include motor shafts, gearbox assemblies, pump components, and rotating equipment found in both commercial and light industrial environments. The phosphate finish provides a degree of break-in lubrication retention, making it a practical choice in applications where rings are installed and removed during routine service.

Key Features

• Fits 22 mm shaft diameter with a 21 mm groove diameter per DIN 471
• Spring steel construction for consistent radial force and reliable retention
• Phosphate finish provides corrosion resistance and aids lubrication retention
• Ring thickness of 1.20 mm and groove width of 1.30 mm for precise fitment
• Meets DIN 471 and ISO 13485:2015 standards
• Metric system of measurement for direct compatibility with metric shaft assemblies

Compatibility

Designed as an OEM-style external retaining ring for metric 22 mm shaft assemblies conforming to DIN 471 groove specifications.

Installation Notes

Installation requires external retaining ring pliers sized for the applicable ring diameter; do not attempt installation with general-purpose pliers, as this risks ring distortion or ejection. Ensure the shaft groove is clean, dimensionally correct, and free of burrs before seating the ring. Power down and de-energize any associated equipment before servicing components retained by this ring. Verify groove depth and width tolerances match DIN 471 specifications to ensure full ring engagement and rated axial load capacity.
