Rotor Clip DSH-25ST Pd External Retaining Ring 25mm

Product Description

The ROTOR CLIP DSH-25ST PD is an external retaining ring designed to secure components on a shaft by seating in a machined groove on the shaft exterior. Manufactured from spring steel with a phosphate finish, this ring provides reliable axial retention in mechanical assemblies. It fits a 25 mm nominal shaft diameter with a groove diameter of 23.9 mm and a ring thickness of 1.20 mm. The phosphate finish offers basic corrosion resistance and reduces galling during installation. This part is specified to DIN 471 and ISO 13485:2015 standards, making it a recognized choice for precision assemblies requiring dimensional consistency.

This external retaining ring is suited for industrial, mechanical, and light assembly applications where shaft-mounted components must be axially retained without threading or welding. Typical install scenarios include gearboxes, motors, pumps, and rotating shaft assemblies found in HVAC equipment, plumbing systems, and general mechanical equipment. It is installed by qualified maintenance technicians and mechanical assemblers working on shaft diameters of 25 mm. The minimum order quantity is 25 pieces per order.

Key Features

• Fits 25 mm nominal shaft diameter with a 23.9 mm groove diameter
• Spring steel construction provides consistent radial tension and retention force
• Phosphate finish for basic corrosion resistance and reduced installation friction
• Conforms to DIN 471 and ISO 13485:2015 dimensional standards
• Ring thickness of 1.20 mm with a groove width of 1.30 mm for a controlled fit
• Groove depth of 0.55 mm with a free outside diameter of 23.2 mm

Compatibility

Designed as a DIN 471-compliant external retaining ring for 25 mm shafts. Compatible with any shaft assembly machined to a 23.9 mm groove diameter, 1.30 mm groove width, and 0.55 mm groove depth per DIN 471 specifications.

Installation Notes

Installation requires external retaining ring pliers sized for 25 mm shaft rings. Always relieve shaft load and de-energize or isolate the associated equipment before servicing. Ensure the groove is free of burrs and debris before seating the ring to avoid improper seating or ring deformation. Do not reuse a ring that has been removed, as spring steel retaining rings may lose retention force after deflection.
