Rotor Clip SE-74ST Pa E Style Retaining Ring 0.75 in

Product Description

The ROTOR CLIP SE-74ST PA is an external E style retaining ring designed to secure components on shafts in a wide range of mechanical assemblies. Manufactured from SAE 1060-1090 spring steel with a phosphate finish, this ring delivers reliable axial retention on 0.75-inch diameter shafts. The three-prong E style design allows for tool-free or plier-assisted installation into the groove without full shaft disassembly. With a ring thickness of 0.05 inches and a hardness rating of 47-52 HRC, it handles moderate dynamic loads and resists deformation under working conditions. This part is sold individually with a minimum order quantity of 100 units.

The SE-74ST PA is suited for industrial, mechanical, and light manufacturing applications where external shaft retention is required. Common installation scenarios include motors, gearboxes, pumps, conveyors, and general power transmission equipment. The phosphate finish provides baseline corrosion resistance for indoor and lightly controlled environments. This ring fits applications specifying a 0.625-inch groove diameter with a groove width of 0.056 inches and a groove depth of 0.062 inches. It is appropriate for use where SAE 1060-1090 or UNS G10600-G10900 spring steel materials are specified.

Installation Notes

Installation and removal should be performed using proper external retaining ring pliers to avoid over-stressing the prongs or distorting the ring. Ensure the shaft groove is clean and free of burrs before seating the ring. Never reuse a ring that has been visibly deformed, over-expanded, or removed from service. Follow applicable machinery safety standards and lock out or tag out rotating equipment before servicing any retained component.
