Rotor Clip CG-400SJ External Spiral Retaining Ring 4 in

Product Description

The ROTOR CLIP CG-400SJ is an external spiral retaining ring designed for 4-inch diameter shafts. It seats in a machined groove to axially retain components on a shaft without requiring secondary fasteners. 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 groove width, this ring is engineered for precise fitment in moderate-load retention applications. Mechanical technicians, maintenance professionals, and industrial assemblers working on rotating equipment or precision machinery are the primary installers.

This external spiral retaining ring is suited for industrial and commercial assembly applications where corrosion resistance and dimensional accuracy are required. The 302 stainless steel construction makes it appropriate for environments exposed to moisture or mild chemical contact. It fits a 4-inch shaft with a groove diameter of 3.792 inches and seats into a groove 0.12 inches wide and 0.104 inches deep. Applications include pump assemblies, drive shafts, gearboxes, and other rotating or reciprocating shaft assemblies where axial component retention is needed.

Key Features

• External spiral design for tool-free hand installation without special pliers in many configurations
• 302 stainless steel construction meets AISI 302 and AMS-5866 material standards
• Certified to ISO 13485:2016, suitable for quality-managed manufacturing environments
• Oil finish provides surface protection and eases installation into machined grooves
• Groove width tolerance of 0.0000 to 0.0050 inches for tight, controlled fitment
• Ring thickness tolerance of -0.0030 to 0.0030 inches for consistent load distribution

Compatibility

Designed as an OEM-style external spiral retaining ring for 4-inch diameter shafts with a groove diameter of 3.792 inches. Confirm groove width and depth dimensions against machined shaft specifications before installation.

Installation Notes

Installation is typically performed by mechanical technicians or industrial maintenance personnel. Before servicing any assembly, de-energize the equipment and relieve any mechanical load or pressure on the shaft. Ensure the shaft groove dimensions match the ring specifications, including groove width, depth, and diameter tolerances, before seating the ring. Spiral retaining rings are installed by winding into the groove and do not require snap-ring pliers, but the shaft and groove surfaces should be clean and free of burrs prior to installation.
