Rotor Clip HO-25ST Pa Internal Snap Retaining Ring

Product Description

The ROTOR CLIP HO-25ST PA is an internal snap retaining ring designed to secure components within a bored housing by seating in a precision-cut groove. Made from 1060/1090 spring steel with a phosphate finish, this ring provides reliable axial retention in applications where a fastener-free assembly is required. The ring measures 0.25 inches bore diameter, with a free outer diameter of 0.28 inches and a ring thickness of 0.015 inches. Groove width is 0.02 inches at a depth of 0.009 inches. Licensed tradespeople and mechanical assemblers working on small-bore housings will find this ring suitable for high-volume production and maintenance use.

This internal retaining ring is used in residential and commercial mechanical assemblies where small-bore housing retention is required. Typical applications include motors, gearboxes, pumps, actuators, and fluid system components that require axial load management without threaded fasteners. The ring installs into an internal groove machined to SAE and ISO tolerances, making it appropriate for precision-machined bores in both OEM manufacturing and field repair contexts. It is sold in minimum order quantities of 100 units per order.

Key Features

• Internal snap ring design fits a 0.25 inch bore diameter for housing-groove retention
• Spring steel construction graded to SAE 1060-1090 for consistent elasticity and load resistance
• Phosphate finish provides corrosion resistance and lubricity for installation and service life
• Thrust load capacity rated at 190 pounds groove safety factor and 426 pounds ring safety factor
• Hardness rated at Rockwell 15N 86-88 for consistent performance under load
• Meets ISO 13485:2016 and SAE standards; does not meet military specifications

Compatibility

Designed as an OEM-style replacement or new-installation internal retaining ring for precision-machined 0.25 inch bore housings conforming to SAE and ISO groove standards.

Installation Notes

Installation requires internal snap ring pliers sized for the bore diameter. The housing groove must be machined to the specified width and depth tolerances before ring installation. Power down or depressurize any system before servicing components that use this ring. Do not over-expand the ring during installation, as spring steel at this gauge can be damaged by excessive deflection.
