Rotor Clip TX-87ST Pa Retaining Ring 7/8 Inch Shaft

Product Description

The ROTOR CLIP TX-87ST PA is an external self-locking retaining ring designed for 7/8-inch diameter shafts. It seats directly on the shaft without requiring a groove, using 16 prongs to grip the shaft surface and resist axial displacement under load. Manufactured from SAE 1060-1090 steel and finished with a phosphate coating for corrosion resistance, this ring delivers a thrust load capacity of 142 pounds. It is used in mechanical assemblies where a groove-free retention method is required and where reliable axial load holding is critical to service life.

This retaining ring is suited for industrial, mechanical, and light-duty trade applications where external shaft retention is needed without machining a groove into the shaft. Typical install scenarios include motor shafts, pump assemblies, gearboxes, and other rotating or reciprocating shaft configurations. It is specified to SAE 1060-1090 and UNS G10600-G10900 standards and meets ISO 13485:2015 requirements. Machinists, millwrights, and mechanical technicians are the primary installers in commercial and industrial settings.

Key Features

• Self-locking design uses 16 prongs to grip shaft without requiring a machined groove
• Rated thrust load capacity of 142 pounds for reliable axial retention
• SAE 1060-1090 steel construction with hardness of 84-86 HR15N
• Phosphate finish provides baseline corrosion and wear resistance
• Ring thickness of 0.015 inches with a tight tolerance of plus or minus 0.002 inches
• Meets SAE 1060-1090, UNS G10600-G10900, and ISO 13485:2015 standards

Compatibility

Designed for external installation on shafts with a nominal diameter of 7/8 inch (0.875 inches), with an acceptable shaft diameter range of 0.870 to 0.880 inches. Suitable as a groove-free external retaining ring in mechanical assemblies conforming to SAE and UNS inch-measurement standards.

Installation Notes

Installation and removal require appropriate retaining ring pliers rated for self-locking external ring styles. Always de-energize and lockout any machinery before servicing shaft components. Verify shaft diameter is within the 0.870 to 0.880 inch tolerance range before installation to ensure proper prong engagement. Do not reuse a ring that has been removed, as prong deformation reduces retention capacity.
