Rotor Clip DHO-25SG External Snap Retaining Ring 25mm

Product Description

The ROTOR CLIP DHO-25SG is an external snap retaining ring engineered for 25 mm shaft diameters with a groove diameter of 26.19 mm. Manufactured from 420 stainless steel with a phosphate finish, this ring provides reliable axial retention of components on shafts in demanding industrial and mechanical assemblies. The ring measures 1.19 mm in thickness and seats into a groove that is 1.30 mm wide and 0.61 mm deep. It conforms to DIN 472 and ISO 13485:2015 standards, making it suitable for precision applications where certified fastener compliance is required. Installation and removal are handled by qualified mechanical and industrial maintenance technicians using standard snap ring pliers.

This retaining ring is suited for use in pump assemblies, motor shafts, gearboxes, hydraulic components, and other rotating or stationary shaft applications where a secure, removable axial stop is needed. The phosphate finish offers a baseline level of corrosion resistance and paint adhesion for applications in moderate-duty environments. The DIN 472 fastener standard applies, confirming metric dimensioning throughout. This part ships in a package quantity of two units.

Key Features

• 420 stainless steel construction offers good strength and moderate corrosion resistance
• Phosphate finish improves surface adhesion and provides baseline corrosion protection
• Conforms to DIN 472 and ISO 13485:2015 standards for certified metric fastener applications
• Groove width of 1.30 mm and groove depth of 0.61 mm for precise, consistent seating
• Metric dimensioning throughout for compatibility with DIN-standard shaft and groove tooling

Compatibility

Designed for use on 25 mm shafts machined to DIN 472 groove specifications, with a groove diameter of 26.19 mm, groove width of 1.30 mm, and groove depth of 0.61 mm. No specific OEM model compatibility was provided in the product data.

Installation Notes

Installation and removal should be performed by a qualified mechanical technician using snap ring pliers sized for the ring's lug holes. Ensure the shaft groove dimensions match DIN 472 specifications before installation to prevent ring failure or improper seating. Always wear appropriate eye protection, as snap rings can release suddenly under spring tension during installation or removal. Confirm all rotating equipment is fully de-energized and locked out before servicing any shaft assembly.
