Rotor Clip DHO-18SG Metric Internal Snap Retaining Ring

Product Description

The ROTOR CLIP DHO-18SG is a metric internal snap retaining ring designed to seat in a machined groove inside a bore and axially retain components such as bearings, bushings, pins, and shafts. Made from 1060/1090 carbon steel with a phosphate finish, this ring fits an 18mm bore diameter with a 19mm nominal size. It measures 19.5mm free outer diameter and carries a thrust load capacity of 1,079 pounds based on groove safety factor and 1,461 pounds based on ring safety factor. The phosphate coating provides baseline corrosion resistance and aids in lubrication retention. This ring is typically installed by maintenance technicians, machinists, and assembly professionals working on mechanical and industrial assemblies.

This retaining ring is suited for use in mechanical assemblies where an internal groove is machined into a bore to accept a snap ring. Typical applications include gearboxes, electric motors, pumps, hydraulic assemblies, and general industrial machinery requiring precise axial component retention. The 1mm ring thickness and 1.1mm groove width by 0.5mm groove depth profile make it appropriate for standard metric internal groove configurations in both OEM production and MRO replacement scenarios.

Key Features

• 18mm bore diameter with 19mm nominal size for standard metric internal groove fitment
• 19.5mm free outer diameter allows controlled snap installation into the groove
• Thrust load capacity of 1,079 lb (groove safety factor) and 1,461 lb (ring safety factor)
• 1060/1090 carbon steel construction meets SAE and UNS G10600-G10900 material standards
• Phosphate finish provides corrosion resistance and surface lubricity
• Rockwell 30N hardness of 66-72 for reliable load-bearing performance

Compatibility

Designed as an OEM-style replacement or production-use internal snap retaining ring for metric bore applications requiring an 18mm bore diameter and 19mm nominal groove size per ISO and SAE standard internal groove profiles.

Installation Notes

Installation requires internal snap ring pliers sized for metric rings. Power down and de-energize any equipment before servicing assemblies containing this ring. Ensure the bore groove is clean, within tolerance, and free of burrs before seating the ring. Do not over-spread the ring during installation, as exceeding the elastic limit will compromise retention force and require ring replacement.
