Rotor Clip DHO-12SG External Snap Retaining Ring 12mm

Product Description

The ROTOR CLIP DHO-12SG is a metric external snap retaining ring designed to seat in a shaft groove and retain components against axial movement. It is manufactured from 420 stainless steel with a phosphate finish, giving it corrosion resistance suitable for demanding mechanical environments. The ring fits a 12 mm shaft diameter with a groove diameter of 12.5 mm and a ring thickness of 0.99 mm. Conforms to DIN 472 and ISO 13485:2015 standards. This fastener is installed by maintenance technicians, millwrights, and mechanical assemblers working on shafts, spindles, and rotating assemblies across industrial and commercial applications. Sold in a package of 5 rings.

The DHO-12SG is suited for use in assemblies where a reliable external retaining ring is needed on a 12 mm shaft. Typical applications include pumps, motors, gearboxes, and fluid-handling equipment where metric-dimensioned components are specified. The phosphate finish supports light lubrication retention and mild corrosion resistance, making this ring a practical choice in environments where 420 stainless steel is an appropriate material selection. The DIN 472 fastener standard ensures dimensional interchangeability with other compliant metric retaining ring hardware.

Installation Notes

Retaining rings of this type are installed and removed using snap ring pliers sized for external rings. Always de-energize and lock out any rotating machinery before servicing shaft components. Verify the shaft groove dimensions match the ring specifications before installation to prevent improper seating. Inspect the groove for burrs or damage that could affect ring retention prior to assembly.
