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

Product Description

The ROTOR CLIP SE-17SS is an external E style retaining ring designed to secure components on shafts in light-duty fastening applications. Manufactured from 15-7 stainless steel to AMS-5529 and UNS S15700 standards, it delivers high hardness in the 63 to 69.5 HRC range alongside corrosion resistance suited for demanding service environments. The ring seats in a shaft groove 0.127 inches in diameter, fits an 11/64 inch (0.1719 inch) shaft diameter, and measures 0.025 inches in thickness. Its three-prong E style profile allows quick installation and removal without specialized removal tooling, making it a practical choice for high-volume assembly and field service work.

This retaining ring is used in mechanical assemblies where a low-profile external ring is needed to retain bearings, bushings, or other components on small-diameter shafts. Typical applications include light machinery, pneumatic tools, small motors, medical device assemblies, and precision instrumentation. The stainless steel construction makes it appropriate for environments with moisture exposure or where material certifications such as ISO 13485:2015 compliance are required. Licensed mechanical assemblers and maintenance technicians are the primary installers in both production and field settings.

Key Features

• E style three-prong design allows fast snap-in installation and removal without specialty tools
• 15-7 stainless steel construction per AMS-5529 and UNS S15700 for corrosion resistance and high strength
• Hardness rating of 63 to 69.5 HRC for wear resistance in demanding assemblies
• Groove diameter of 0.127 inches with a tolerance of 0.000 to 0.002 inches for precise fitment
• Ring thickness of 0.025 inches with a tight tolerance of -0.002 to 0.002 inches
• Meets ISO 13485:2015 standards, supporting use in medical device manufacturing environments

Compatibility

Designed for use on shafts with an 11/64 inch (0.1719 inch) diameter and a groove diameter of 0.127 inches. Refer to the manufacturer groove specification for proper mating groove dimensions before installation.

Installation Notes

Installation is performed by mechanical assemblers or maintenance technicians using standard E ring applicator pliers or manual press tools. Ensure the shaft groove is clean and free of burrs before seating the ring to achieve full groove engagement across all three prongs. Confirm the groove width of 0.029 inches and groove depth of 0.022 inches match the shaft before installation. Never reuse a retaining ring that has been removed, as the prongs may be deformed and retention force compromised.
