Rotor Clip CG-500SJ External Spiral Retaining Ring

Product Description

The ROTOR CLIP CG-500SJ is an external spiral retaining ring engineered for 5-inch diameter shafts. It seats in a machined groove with a 4.79-inch groove diameter and holds axial position of components without requiring a secondary fastener. The ring is manufactured from AISI 302 stainless steel with an oil finish, meeting AMS-5866 and ISO 13485:2016 standards. At 0.111 inches thick and 0.12 inches wide to match the groove, it provides reliable retention in demanding environments where corrosion resistance is required. Mechanical assemblers and maintenance technicians install this ring in shaft-and-bore assemblies across industrial, HVAC, and equipment manufacturing applications.

This ring is suited for assemblies where an external groove on a 5-inch shaft retains a bearing, gear, pulley, or similar component. The spiral design allows installation with standard snap ring pliers without requiring a radial gap, which simplifies service in tight clearance situations. Its 302 stainless steel construction makes it appropriate for wet, corrosive, or sanitary environments where carbon steel retaining rings would be unsuitable.

Compatibility

Designed for external installation on shafts with a 5-inch nominal diameter and a machined retaining ring groove matching the specified 4.79-inch groove diameter, 0.12-inch groove width, and 0.105-inch groove depth.

Installation Notes

Installation and removal should be performed with snap ring pliers rated for the ring diameter; improper tools can deform the spiral ring and compromise retention. Verify groove dimensions match the specified tolerances before installation, as an undersized or oversized groove will affect holding capacity. Power down and de-energize any rotating equipment before servicing shaft components. Follow applicable machinery safety standards and the equipment manufacturer's service procedures during disassembly and reassembly.
