The Rotor Clip E-37ST PA B100 is a radially assembled external retaining ring designed for secure shaft retention in various industrial applications. This retaining ring features a 0.375-inch shaft diameter and a 0.660-inch outside diameter, making it suitable for standard-sized equipment. Constructed from SAE 1060-1090 carbon steel, it offers high tensile strength and durability, ensuring reliable performance in demanding environments. The phosphate finish enhances corrosion resistance, extending the product's service life in harsh conditions. The E-37ST PA B100 is radially installed into machined grooves on shafts, providing a protruding "shoulder" for effective retention of assemblies. It accommodates lower thrust loadings compared to axial retaining rings and does not have lug holes, facilitating easy installation using retaining ring applicators. This design makes it an economical alternative to axially assembled external tapered section rings. With a maximum load capacity of 690 lbs and a limiting speed of 20,000 rpm, the E-37ST PA B100 is engineered to meet the demands of various industrial applications, including automotive, machinery, and manufacturing sectors. Its robust construction and user-friendly design contribute to operational efficiency and reliability.
