Rotor Clip SE-17ST Pa E Style Retaining Ring 11/64 in

Product Description

The ROTOR CLIP SE-17ST PA is an external E style retaining ring designed to secure components on small-diameter shafts without the need for threading or additional fasteners. Manufactured from SAE 1060-1090 spring steel, this ring fits a shaft diameter of 11/64 inches (0.1719 inches) and seats in a groove with a diameter of 0.127 inches. The phosphate finish provides a baseline level of corrosion resistance. With a ring thickness of 0.025 inches and a three-prong configuration, it delivers reliable axial retention in compact assemblies. Installed by mechanical technicians, machinists, and assembly professionals across light industrial and OEM applications.

This retaining ring is suited for use in small mechanical assemblies, precision instruments, motors, and similar equipment where space constraints require a low-profile fastening solution. The E style design allows for quick tool-assisted installation and removal without disassembly of surrounding components. It is commonly found in residential and commercial equipment including HVAC actuators, small motors, and pump assemblies where shaft retention on diameters under 3/16 inches is required.

Key Features

• E style external design provides three-prong axial retention on 11/64 inch shafts
• SAE 1060-1090 spring steel construction meets UNS G10600-G10900 and ISO 13485:2015 standards
• Phosphate finish for surface protection in typical indoor mechanical environments
• Ring thickness of 0.025 inches fits groove width of 0.029 inches with controlled tolerance
• Hardness rated 66.5-71 HR30N for consistent spring retention force
• Free outside diameter of 0.312 inches keeps the footprint minimal in tight assemblies

Compatibility

Designed as an OEM-style external E style retaining ring for 11/64 inch diameter shafts with a groove diameter of 0.127 inches. Verify groove width and depth against the 0.029 inch and 0.022 inch specifications respectively before installation.

Installation Notes

Installation and removal should be performed using retaining ring pliers appropriate for E style rings to avoid distorting the prongs or the ring body. Power down or de-energize any equipment before servicing assemblies that contain this ring. Do not reuse a ring that has been overstressed or visibly deformed during removal. Follow applicable machinery safety standards and equipment manufacturer procedures when servicing assemblies.
