Rotor Clip DSH-8SG External Retaining Ring 8mm Shaft

Product Description

The ROTOR CLIP DSH-8SG is a metric external retaining ring designed to secure components on shafts and prevent axial movement in mechanical assemblies. Manufactured from 420 stainless steel with a phosphate and oil finish, it delivers corrosion resistance and consistent holding force in demanding environments. The ring seats in a precision groove on an 8 mm diameter shaft, with a groove diameter of 7.6 mm and a ring thickness of 0.80 mm. Hardness is rated at 63-69.5 HR30N, providing reliable performance under dynamic and static load conditions. Mechanical technicians, maintenance professionals, and precision assembly technicians install these rings in production and field service applications.

This external retaining ring is suited for use in light machinery, pumps, motors, instrumentation, and general mechanical assemblies where an 8 mm shaft diameter is specified. The metric dimensioning and DIN 471 compliance make it appropriate for equipment built to European or ISO standards. The phosphate and oil finish provides baseline corrosion protection for indoor and light-duty industrial environments. Each package contains 5 rings, with a minimum order quantity of 1 package.

Key Features

• 420 stainless steel construction with phosphate and oil finish for corrosion resistance

• ISO 13485:2015 compliant manufacturing standard
• Groove diameter tolerance of -0.06 to +0.06 mm for precise fitment
• Compact ring thickness of 0.80 mm with tight tolerance of -0.05 mm

Compatibility

Designed as an OEM-style external retaining ring for 8 mm shaft diameter applications conforming to DIN 471 groove specifications.

Installation Notes

External retaining rings of this type are installed by mechanical technicians using retaining ring pliers sized for the ring free diameter. Ensure the shaft groove is clean and within specified tolerance before installation. Do not over-spread the ring during installation, as exceeding the free diameter tolerance can cause permanent deformation. Always de-energize and lock out equipment before servicing any shaft or rotating assembly.
