Rotor Clip DHO-30ST Pd 30mm Internal Snap Retaining Ring

Product Description

The ROTOR CLIP DHO-30ST PD is a metric internal snap retaining ring designed to seat in a machined internal groove within a bore and secure components against axial movement. Made from spring steel with a phosphate finish, this ring is suited for precision assemblies where reliable axial retention is required. It fits a 30mm nominal bore diameter with a free outer diameter of 32.1 mm, a ring thickness of 1.2 mm, and is designed to seat in a groove measuring 1.3 mm wide by 0.7 mm deep. Licensed tradespeople and assembly technicians in industrial maintenance, OEM manufacturing, and mechanical repair applications commonly install this part.

This retaining ring is used in mechanical assemblies where a component must be retained inside a cylindrical bore. Typical applications include gearboxes, motor housings, hydraulic cylinders, pumps, and general industrial equipment requiring a compact, low-profile axial stop inside a 30mm bore. The phosphate finish provides moderate corrosion resistance and aids in lubrication retention during assembly and service cycles.

Key Features

• Internal snap ring design seats inside a machined groove to retain components axially within a bore
• Spring steel construction delivers consistent radial spring force and long service life
• Phosphate finish improves corrosion resistance and surface lubricity
• 30mm nominal bore size with a free outer diameter of 32.1 mm for precise groove engagement
• Groove diameter tolerance of 0.25 mm and ring thickness tolerance of -0.06 mm for controlled fit
• Thrust load capacity of 11.30 kN at the groove and 13.7 kN at the ring

Compatibility

Designed as an OEM-style metric internal retaining ring for mechanical assemblies with a 30mm nominal internal bore diameter machined to accept a 1.3 mm wide by 0.7 mm deep retaining ring groove per applicable metric standards.

Installation Notes

Installation requires internal snap ring pliers sized for the 30mm bore to safely compress and seat the ring without distorting the ring profile. Ensure the groove is clean and free of burrs before installation. Always wear eye protection when handling snap rings, as accidental release can cause injury. Confirm bore groove dimensions match the ring specifications before installation to avoid improper seating or loss of retention capacity.
