Rotor Clip CG-400ST Oil Spiral Retaining Ring 4 in Shaft

Product Description

The ROTOR CLIP CG-400ST OIL is an external spiral retaining ring designed to secure components on a 4-inch diameter shaft. Manufactured from SAE 1060-1090 steel and finished with an oil coating for corrosion resistance during storage and installation, this ring seats into a 3.792-inch groove diameter and provides a reliable axial retention solution. At 0.111 inches thick with a groove width of 0.12 inches, it suits heavy-duty rotating and stationary shaft assemblies. Machinists, maintenance technicians, and industrial assembly professionals install this type of ring where a one-piece, no-ear spiral design is required for clean, low-profile retention.

This external spiral retaining ring is used in industrial machinery, power transmission equipment, pumps, motors, and similar mechanical assemblies where a 4-inch shaft is present. The spiral design allows installation without specialized pliers in some applications and eliminates ear interference in confined bores. It is suited for both OEM production and MRO replacement on shafts meeting the specified groove dimensions. Minimum order quantity is 2 units, with individual package quantity of 1.

Key Features

• External spiral design provides low-profile axial retention without protruding ears
• Fits 4-inch shaft diameter with a 3.792-inch groove diameter
• SAE 1060-1090 steel construction for strength in demanding mechanical environments
• Oil finish coating protects against corrosion during storage and handling
• Groove width of 0.12 inches and ring thickness of 0.111 inches for precise fitment
• Meets SAE 1060-1090 and UNS G10600-G10900 material standards

Compatibility

Designed for use on external shafts with a 4-inch nominal diameter and a groove diameter of 3.792 inches. Groove width tolerance is 0.0000 to 0.0050 inches and groove diameter tolerance is -0.0060 to 0.0060 inches. Verify shaft and groove dimensions against these specifications before installation.

Installation Notes

Installation is performed by machinists or mechanical maintenance technicians following standard shaft-and-groove assembly procedures. Power down and de-energize all associated equipment before servicing any rotating shaft assembly. Confirm groove dimensions and tolerances match the ring specifications prior to installation. Do not reuse a ring that has been removed, as spiral retaining rings are intended for single installation.
