The Rotor Clip E-25SS MPS 1/4" Stainless Steel External E Retaining Ring is engineered to provide secure retention in shaft assemblies, effectively preventing axial movement and ensuring component stability. Designed for 1/4" shaft diameters, this ring features a groove diameter of 0.21" and a thickness of 0.025", making it suitable for applications requiring moderate load capacities. Constructed from stainless steel (PH15-7 Mo), it offers enhanced corrosion resistance, ensuring durability in various industrial environments. The E-style design, characterized by three prongs that contact the bottom of the groove, provides a shoulder for effective retention of assemblies. This design allows for easy installation using retaining ring applicators, eliminating the need for lug holes. The E-25SS MPS ring is an economical alternative to axially assembled external tapered section rings, offering a cost-effective solution without compromising performance. Its maximum load capacity is 255 lbs, with a limiting speed of 25,000 rpm, making it suitable for applications with moderate thrust loads and rotational speeds. The ring's external installation into machined grooves on shafts accommodates lower thrust loadings than axial retaining rings, providing versatility in various mechanical assemblies. The E-25SS MPS ring is compatible with Rotor Clip's retaining ring applicators, facilitating efficient and secure installation. Its stainless steel construction ensures longevity and reliability, reducing the frequency of replacements and maintenance downtime. This retaining ring is ideal for industries such as automotive, machinery, and equipment manufacturing, where secure component retention is critical for operational efficiency and safety.
