Rotor Clip HO-125ST Pa Internal Snap Retaining Ring

Product Description

The ROTOR CLIP HO-125ST PA is a steel internal snap retaining ring designed for use in bored housings and cylindrical assemblies. It seats into a machined groove to axially retain shafts, bearings, pins, or other components without fasteners. Manufactured from 1060/1090 spring steel with a phosphate finish, this ring provides reliable retention in applications where vibration, thrust load, or lateral movement must be controlled. With a thrust load capacity of 4,250 pounds at the groove safety factor and 8,932 pounds at the ring safety factor, it handles demanding mechanical loads in a compact profile. Machinists, maintenance technicians, and assembly professionals install this ring using standard snap ring pliers.

This internal retaining ring is suited for residential and industrial mechanical assemblies where a 1.25-inch bore diameter is present. Common applications include gearboxes, hydraulic cylinders, electric motors, pumps, and automotive or industrial drivetrain components. The ring installs into a groove machined to 0.056 inches wide and 0.04 inches deep. It is sold individually with a minimum order quantity of 100 units, making it appropriate for production assembly lines, MRO stocking, or fleet maintenance operations.

• Thrust load capacity of 4,250 lb (groove safety factor) and 8,932 lb (ring safety factor)
• Groove width of 0.056 inches and groove depth of 0.04 inches for precise fitment
• Meets ISO 13485:2016 standards; UNSPSC Code 31163202

Compatibility

Designed as an OEM-style internal retaining ring for any grooved bore measuring 1.25 inches in diameter machined to accept a 0.056-inch-wide groove per applicable SAE and ISO dimensional standards.

Installation Notes

Installation and removal require snap ring pliers sized for internal rings; do not use open-jaw pliers or improvised tools, as they can distort the ring or cause it to eject under tension. De-energize, depressurize, or lock out the assembly per applicable safety procedures before service. Groove dimensions in the housing must conform to the specified tolerances to achieve rated thrust load values. Wear eye protection during installation, as internal snap rings are under spring tension and can release unexpectedly.
