Rotor Clip TI-87ST Pa Internal Retaining Ring 7/8 in

Product Description

The ROTOR CLIP TI-87ST PA is a steel internal self-locking retaining ring designed to secure components within a bored housing without requiring a groove in the bore. It holds its position through radial tension against the bore wall, eliminating the need for machined grooves and reducing assembly complexity. Built from SAE 1060-1090 high-carbon steel with a phosphate finish for corrosion resistance, it carries a thrust load capacity of 71 pounds. Ring thickness is 0.015 inches with a tolerance of -0.002 to +0.002 inches. This ring is installed by machinists, mechanical assemblers, and MRO technicians working on precision assemblies, motors, pumps, and gearboxes.

This retaining ring fits a 0.625 inch inside diameter and is suited for use in light-to-medium duty mechanical assemblies where a groove-free bore retention solution is required. Common applications include small motors, shafts, housings, and instrumentation components in industrial, commercial, and OEM manufacturing environments. Its self-locking design makes it a practical choice where conventional snap rings are not feasible due to bore geometry or cost constraints.

Key Features

• Self-locking design retains components in bored housings without a machined groove
• 71 pound thrust load capacity for light-to-medium duty applications
• SAE 1060-1090 high-carbon steel construction for strength and durability
• Phosphate finish provides baseline corrosion resistance
• Rockwell 15N hardness of 84-88 for consistent spring performance
• Ring thickness of 0.015 inches with tight tolerance of plus or minus 0.002 inches

Compatibility

Designed as an OEM-style internal self-locking retaining ring for 0.625 inch inside diameter bore applications in industrial and mechanical assemblies.

Installation Notes

Installation is typically performed by machinists or mechanical technicians using retaining ring pliers appropriate for internal self-locking ring styles. Ensure the bore is clean and free of burrs before installation to avoid damage to the ring or seating surface. Confirm thrust load requirements do not exceed the rated 71 pound capacity before specifying this ring in the assembly. Always de-energize and lockout any equipment before servicing assemblies containing retaining rings.
