Rotor Clip KG-143ST Oil Internal Spiral Retaining Ring

Product Description

The ROTOR CLIP KG-143ST OIL is a steel internal spiral retaining ring designed for use in bores with a nominal diameter of 1.4375 inches. It provides reliable axial retention of shafts, bearings, and other components seated in a housing bore. Manufactured from 1060/1090 grade steel with an oil finish for corrosion inhibition, the ring seats in a precision-machined groove and delivers a thrust load capacity of 4,580 pounds at the groove safety factor and 9,490 pounds at the ring safety factor. Machinists, maintenance technicians, and mechanical assembly professionals install this ring type across a wide range of industrial and mechanical applications.

This internal spiral retaining ring is suited for use in rotating assemblies, gearboxes, pumps, motors, and similar equipment where a positive axial stop is required inside a bored housing. The oil finish makes it appropriate for applications where mild corrosion protection is needed during storage or service. It is sold individually with a minimum order quantity of 5 units, making it practical for both repair and production-line use.

Key Features

• Internal spiral ring design installs from one end of the bore without special pliers in many configurations
• 1060/1090 grade steel construction provides strength suitable for high thrust load applications
• Oil finish provides corrosion inhibition during storage and service
• Groove width of 0.056 inches with a tolerance of 0.000 to 0.004 inches for precise groove fit
• Ring thickness of 0.05 inches with a tolerance of -0.002 to 0.002 inches
• Thrust load capacity of 4,580 pounds groove safety factor and 9,490 pounds ring safety factor

Compatibility

Designed as a direct-fit internal spiral retaining ring for bored housings with a 1.4375-inch nominal bore diameter requiring a groove width of 0.056 inches and groove depth of 0.045 inches. Conforms to SAE 1060-1090 and ISO 13485:2016 material standards.

Installation Notes

Installation is typically performed by mechanical assembly technicians or maintenance machinists. Ensure the bore groove is machined to the specified groove width and depth tolerances before installation. De-energize and lock out all equipment before servicing any assembly containing retaining rings. Inspect the ring for deformation or damage before installation, as a compromised ring will not achieve rated thrust load capacity.
