Rotor Clip TX-43ST Pa Retaining Ring 7/16 in Shaft

Product Description

The ROTOR CLIP TX-43ST PA is an external self-locking retaining ring designed to secure components on shafts without requiring a groove. Manufactured from SAE 1060-1090 steel (UNS G10600-G10900) and finished with a phosphate coating for corrosion resistance, this ring fits a 7/16 inch nominal shaft diameter (0.4375 inches decimal). The 10-prong self-locking design grips the shaft directly, providing a thrust load capacity of 122 pounds. Ring thickness is 0.015 inches with a tolerance of -0.002 to +0.002 inches. Machinists, maintenance technicians, and assembly line professionals install this hardware in mechanical assemblies where grooveless retention is required.

This retaining ring is suited for light-duty shaft retention applications in industrial, mechanical, and trade equipment assemblies. It is commonly installed on smooth shafts in motors, pumps, gearboxes, and other rotating assemblies where a traditional grooved retaining ring is not practical. The phosphate finish makes it appropriate for indoor or lightly protected environments. The minimum qualifying shaft diameter is 0.432 inches and the maximum is 0.442 inches, so shaft diameter must be confirmed before installation.

Compatibility

Designed as a grooveless external self-locking retaining ring for smooth shafts with a nominal diameter of 7/16 inch (0.4375 inches). Verify shaft diameter falls within the 0.432 to 0.442 inch acceptable range before installation.

Installation Notes

Installation and removal should be performed by a qualified mechanical technician using appropriate retaining ring pliers or application tooling specified for self-locking rings. Always de-energize and lock out the equipment before servicing any shaft-mounted components. Do not reuse a retaining ring that has been removed, as prong grip force may be reduced. Verify shaft diameter with calipers prior to installation to confirm fit within the specified tolerance range.
