Rotor Clip E-15ST Pa B100 E Style Retaining Ring

Product Description

The ROTOR CLIP E-15ST PA B100 is an external E style retaining ring designed for use on shafts with a 5/32 inch (0.1563 inch decimal) diameter. Manufactured from SAE 1060-1090 steel with a phosphate finish, this three-prong ring seats into a 0.116 inch groove diameter and provides reliable axial retention of components on small-diameter shafts. With a ring thickness of 0.025 inches and a hardness rating of 66.5-71 HR30N, it delivers consistent holding force in precision assemblies. This part ships in a minimum order quantity of 100 units.

E style retaining rings of this size are commonly used in light mechanical assemblies, small appliance components, and equipment subassemblies where compact axial retention is required on shafts under 3/16 inch in diameter. Typical applications include motor shafts, gear train assemblies, and similar precision fastening situations encountered in HVAC equipment, plumbing valve assemblies, and electrical device manufacturing. Installation requires no special tooling beyond standard retaining ring pliers suited to the E style profile.

Compatibility

Designed as an OEM-style external retaining ring for 5/32 inch diameter shafts with a 0.116 inch groove diameter, suitable for precision mechanical assemblies requiring compact axial retention.

Installation Notes

Installation and removal should be performed by a qualified mechanic or assembler using E style retaining ring pliers appropriate for the ring size. Ensure the shaft and groove are clean and free of burrs before seating the ring. De-energize or fully power down any equipment before servicing components retained by this ring. Do not reuse a ring that has been deformed or removed from service, as deformation compromises the retention force.
