Rotor Clip DHO-16SG 16mm Metric Internal Snap Ring

Product Description

The ROTOR CLIP DHO-16SG is a metric internal snap retaining ring designed for 16mm bore diameters. It seats in a machined internal groove to secure shafts, pins, and components against axial movement without the need for threading or welding. Manufactured from SAE 1060-1090 carbon steel with a phosphate finish, this ring delivers reliable holding force in standard bore applications. Key dimensional specs include a 16.8mm nominal size, a 17.3mm free outer diameter, 1.1mm groove width, 0.4mm groove depth, and 1mm ring thickness. Thrust load capacity reaches 1,236.4 pounds at the ring safety factor and 764.3 pounds at the groove safety factor. Rockwell 30N hardness falls in the 66-72 range.

This retaining ring is suited for light to medium-duty mechanical assemblies found in HVAC equipment, pumps, motors, and general industrial hardware. It is typically installed by maintenance technicians and mechanical assemblers working on rotating or reciprocating assemblies where a low-profile, tool-installed fastener is required. The phosphate finish provides corrosion resistance suitable for indoor and sheltered mechanical environments. Package quantity is 5 rings per order.

Compatibility

Designed as a standard metric internal snap retaining ring for 16mm bore assemblies requiring an internal groove-mounted fastener in mechanical and industrial applications.

Installation Notes

Internal snap retaining rings require internal snap ring pliers for proper installation and removal. Always de-energize and lock out any equipment before servicing components that use retaining rings. Verify groove dimensions match the ring specifications before installation to avoid overloading the ring or groove. Follow applicable ANSI and OEM assembly guidelines for snap ring fastener installations.
