Rotor Clip CG-187ST Oil Spiral Retaining Ring 1-7/8 in

Product Description

The ROTOR CLIP CG-187ST OIL is an external spiral retaining ring designed to secure components on a 1-7/8 inch diameter shaft. Manufactured from SAE 1060-1090 steel (UNS G10600-G10900), the ring features an oil finish that provides corrosion resistance and eases installation into the groove. With a groove diameter of 1.769 inches, a ring thickness of 0.062 inches, and a groove width of 0.068 inches, this ring delivers precise, low-profile retention in mechanical assemblies. It is installed and serviced by maintenance technicians and mechanical assemblers working in industrial, HVAC, and general manufacturing applications.

This external spiral retaining ring is suited for use wherever a 1-7/8 inch shaft requires axial retention of a bearing, gear, pulley, or similar component. The spiral design allows single-turn installation without specialty pliers in many applications, making it practical for production-line and field-service environments. Its compact cross-section fits tight bore clearances common in pump assemblies, fan shaft assemblies, and rotating mechanical equipment across residential, commercial, and light industrial settings.

Key Features

• External spiral ring design for 1-7/8 inch shaft diameter
• SAE 1060-1090 steel construction for reliable tensile strength in rotating assemblies
• Oil finish over steel for corrosion resistance and reduced installation friction
• Groove diameter of 1.769 inches with tolerance of -0.005 to +0.005 inches
• Ring thickness of 0.062 inches fits tight axial clearance applications
• Conforms to SAE 1060-1090, UNS G10600-G10900, and ISO 13485:2015 standards

Compatibility

Designed as a standard external spiral retaining ring for mechanical shafts with a 1-7/8 inch nominal diameter and a groove width of 0.068 inches. Verify groove dimensions against engineering drawings before installation to confirm fitment.

Installation Notes

Installation is performed by qualified mechanical technicians or assemblers. De-energize and lock out all rotating equipment before servicing any shaft-mounted components. Confirm groove dimensions, including diameter, width, and depth, match the ring specifications prior to installation. Avoid over-stressing the ring during assembly; use appropriate retaining ring pliers or installation tooling designed for spiral rings to prevent deformation.
