Rotor Clip CG-350SJ External Spiral Retaining Ring

Product Description

The ROTOR CLIP CG-350SJ 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. It fits a 3-1/2 inch shaft diameter and seats in a groove measuring 3.316 inches in diameter and 0.12 inches wide. The spiral retaining ring design allows for installation and removal without special pliers in many applications, making it a practical choice for maintenance technicians and assemblers working in high-volume or precision environments.

This retaining ring is suited for use in shaft assemblies where corrosion resistance and dimensional precision are required. Typical applications include pumps, motors, gearboxes, and other rotating equipment found in commercial, industrial, and OEM manufacturing settings. The 302 stainless steel material makes it appropriate for environments with exposure to moisture or mild chemicals. Licensed mechanical assemblers, maintenance technicians, and OEM production staff are the primary installers of this component.

Key Features

• External spiral design for shaft-mounted retention without need for traditional snap ring pliers in many setups
• AISI 302 stainless steel construction for corrosion resistance in wet or mildly corrosive environments
• Meets AMS-5866 and ISO 13485:2016 standards for material and quality compliance
• Precise groove engagement: 0.12 inch groove width and 0.092 inch groove depth for reliable seating
• Ring thickness of 0.111 inches with tight tolerance of plus or minus 0.003 inches for consistent fit
• Oil finish applied for surface protection and ease of installation

Compatibility

Designed as an OEM-style external spiral retaining ring for 3-1/2 inch shafts requiring a groove diameter of 3.316 inches. Verify groove width, groove depth, and shaft diameter tolerances against assembly drawings before installation.

Installation Notes

Installation should be performed by qualified mechanical assemblers or maintenance technicians familiar with retaining ring applications. Before installation, ensure the shaft groove is clean, free of burrs, and within specified tolerances. Use appropriate spiral retaining ring installation tools to avoid deforming the ring during seating. Do not reuse a ring that has been removed, as repeated installation can compromise retention force.
