Rotor Clip CG-162SJ External Spiral Retaining Ring

Product Description

The ROTOR CLIP CG-162SJ is an external spiral retaining ring designed for use on shafts with a 1.625-inch diameter. Manufactured from AISI 302 stainless steel and finished with a light oil coating, this ring seats into a precision-machined external groove to axially retain components such as bearings, gears, or collars. The groove diameter is 1.529 inches, ring thickness is 0.062 inches, and the free diameter measures 1.513 inches. These tight tolerances make it well suited for applications where consistent retention force and corrosion resistance are required. Installation and removal are performed with spiral ring pliers, and no secondary fasteners are needed.

This retaining ring is used in mechanical assemblies across industrial, HVAC, pump, and rotating equipment applications. It is appropriate wherever a low-profile, externally mounted shaft retainer is required and where stainless steel construction is preferred for resistance to moisture, mild chemicals, or elevated humidity environments. The spiral design allows single-turn installation without special tooling beyond standard spiral ring pliers, making it a practical choice for production and field service work alike.

Key Features

• External spiral ring design installs directly onto a 1.625-inch shaft without disassembly of adjacent components
• AISI 302 stainless steel construction meets AMS-5866 and ISO 13485:2016 standards
• Groove diameter of 1.529 inches with a tolerance of -0.005 to +0.005 inches for precise fitment
• Ring thickness of 0.062 inches with a tight tolerance of -0.002 to +0.002 inches
• Oil finish provides light corrosion protection during storage and installation
• Groove width of 0.068 inches accommodates standard external groove profiles

Compatibility

Designed as an OEM-style external spiral retaining ring for 1.625-inch shafts machined to a 1.529-inch groove diameter per AISI 302 and AMS-5866 specifications.

Installation Notes

Installation and removal should be performed by a qualified mechanic or assembly technician using spiral retaining ring pliers sized for this diameter. Ensure the shaft groove is clean, free of burrs, and within the specified groove width and depth tolerances before installation. De-energize and lock out all equipment before servicing any rotating assembly. Do not use a screwdriver or improvised tool to seat or remove the ring, as this can deform the ring or damage the groove.
