The Rotor Clip E-50ST PA B100 is a radially assembled external retaining ring designed for shafts with a 0.5" diameter. Manufactured from carbon steel (SAE 1060-1090) and finished with a phosphate coating, this ring offers enhanced corrosion resistance and durability, making it suitable for various industrial applications. Its 'E' shape, characterized by three prongs, ensures effective retention by making contact with the bottom of the groove, providing a shoulder for assemblies. This design allows for easy installation into machined grooves on shafts, accommodating lower thrust loadings compared to axial retaining rings. The absence of lug holes facilitates straightforward installation using retaining ring applicators, streamlining the assembly process. With a maximum load capacity of 1,110 lbs and a limiting speed of 14,000 rpm, the E-50ST PA B100 is engineered to meet the demands of high-performance environments. Its phosphate finish not only offers corrosion resistance but also contributes to the ring's overall strength and longevity. This retaining ring serves as an economical alternative to axially assembled external tapered section rings, providing a reliable solution for securing components in place. Its design and material composition ensure consistent performance, reducing the risk of component displacement and enhancing the overall reliability of mechanical assemblies. The E-50ST PA B100 is an essential component for industries requiring secure and efficient retention solutions, offering both performance and value.
