Rotor Clip SE-118ST Zd E Style Retaining Ring 1-3/16 in

Product Description

The ROTOR CLIP SE-118ST ZD is an external E style retaining ring designed for 1-3/16 inch (1.1875 inch decimal) shaft diameters. It seats in a machined external groove to retain components on shafts, spindles, and pins without requiring threaded fasteners. Manufactured from SAE 1060-1090 carbon steel with a yellow zinc dichromate finish, the ring delivers hardness in the 47-52 HRC range for reliable retention under load. The three-prong E style design allows for side-loading installation with a flat-blade or E-ring plier tool. Licensed machinists, MRO technicians, and mechanical assembly trades use this style of ring across a wide range of rotating equipment applications.

This retaining ring is suited for residential and commercial mechanical assemblies where a compact external groove retainer is required on a 1-3/16 inch shaft. Typical applications include electric motor shafts, pump impeller assemblies, gear train components, and general industrial machine sub-assemblies. The zinc dichromate finish provides a baseline level of corrosion resistance appropriate for indoor mechanical environments. This part is sold individually but carries a minimum order quantity of 100 units, making it practical for production runs, MRO stocking, or field service kits.

Key Features

• E style three-prong design allows tool-free side-load installation and removal without special circlip pliers in most applications

• SAE 1060-1090 carbon steel construction graded to UNS G10600-G10900 for consistent material properties
• Hardness rating of 47-52 HRC provides resistance to deformation under axial load
• Yellow zinc dichromate finish for corrosion resistance in standard indoor service environments
• Conforms to SAE 1060-1090, UNS G10600-G10900, and ISO 13485:2015 standards

Compatibility

Designed as an OEM-style external E style retaining ring for shafts with a 1-3/16 inch diameter and a machined external groove meeting the dimensional specifications listed below.

Installation Notes

Installation and removal should be performed by a qualified mechanical technician. Always de-energize and lock out the equipment before servicing any shaft-mounted components. Use a proper E-ring installation tool or flat-blade plier sized for the ring to avoid overspringing the prongs or damaging the groove. Inspect the groove dimensions against the tolerances listed in the specifications before installation to ensure a secure fit.
