Rotor Clip CG-187SJ External Spiral Retaining Ring

Product Description

The ROTOR CLIP CG-187SJ is an external spiral retaining ring designed to secure components on shafts in industrial and mechanical assemblies. Manufactured from AISI 302 stainless steel with an oil finish, this ring meets AMS-5866 and ISO 13485:2016 standards, making it suitable for applications where corrosion resistance and dimensional precision are required. It fits a 1-7/8 inch shaft diameter with a groove diameter of 1.769 inches and a ring thickness of 0.062 inches. Spiral-wound retaining rings install without special pliers in many configurations, seating directly into the machined groove to provide reliable axial retention.

This ring is used in light and medium-duty mechanical assemblies across industrial equipment, hydraulic cylinders, pump shafts, and rotating machinery where an external retaining ring is specified. Its stainless steel construction makes it appropriate for applications exposed to moisture, mild chemicals, or sanitary requirements. Maintenance technicians, machine builders, and MRO professionals install this type of ring during assembly and overhaul work on rotating or reciprocating shaft assemblies.

Key Features

• External spiral design installs without retaining ring pliers on most applications
• AISI 302 stainless steel construction provides corrosion resistance
• Meets AMS-5866 and ISO 13485:2016 standards for material and dimensional compliance
• Oil finish applied for corrosion protection during storage and handling
• Precise groove diameter tolerance of -0.005 to 0.005 inches for consistent fitment
• Ring thickness tolerance held to -0.003 to 0.003 inches for reliable axial load performance

Compatibility

Designed for external installation on 1-7/8 inch diameter shafts machined to accept a groove diameter of 1.769 inches and a groove width of 0.068 inches per the specifications defined by AISI 302 and AMS-5866 standards.

Installation Notes

Installation and removal of spiral retaining rings is typically performed by maintenance technicians and machine assemblers. Power down and de-energize all equipment before servicing shaft assemblies. Verify the shaft groove dimensions match the ring specifications before installation to ensure proper seating and axial retention. Do not reuse a ring that has been removed, as deformation during removal compromises retention force.
