Rotor Clip DSH-17SG External Retaining Ring 17mm Stainless

Product Description

The ROTOR CLIP DSH-17SG is an external retaining ring engineered for shaft retention applications requiring corrosion resistance and precise dimensional control. Manufactured from DIN 1.4122 stainless steel with a passivated finish, it fits a 17 mm shaft diameter and seats into a groove with a 16.2 mm groove diameter. At 1 mm ring thickness and a free inside diameter of 15.7 mm, this ring maintains secure axial retention under mechanical load. Hardness is rated at 63-69.5 HR30N, suitable for demanding service conditions. This part is sold in a package quantity of 5, with a minimum order quantity of 1 package.

The DSH-17SG is used in mechanical assemblies where an external retaining ring is required to secure components on a shaft against axial movement. Typical applications include industrial machinery, pumps, motors, and precision equipment where metric dimensioning is standard and stainless steel is specified for corrosion resistance or cleanroom compatibility. It conforms to ISO 13485:2016 standards, making it appropriate for assemblies governed by that specification. Maintenance technicians and mechanical assemblers working on metric-dimensioned equipment are the primary installers.

Installation Notes

External retaining rings of this type are installed and removed by mechanical assemblers or maintenance technicians using appropriate retaining ring pliers sized for the ring diameter. Ensure the shaft groove dimensions match the ring specifications before installation to prevent improper seating or ring failure. Always de-energize and lock out equipment before servicing any assembly containing retaining rings. Avoid using flat-blade tools that can distort the ring or damage the groove.
