The ROTOR CLIP HO-100ST PA is a high-quality internal retaining ring designed for 1" housing diameters, offering a robust solution for securing components within a housing or bore. Manufactured from carbon spring steel (SAE 1060-1090), this ring features a phosphate coating that enhances corrosion resistance, making it suitable for various industrial applications where durability and reliability are paramount. The HO-100ST PA is axially assembled and installed into machined grooves, providing a secure fit that holds assemblies in place effectively. Its tapered section design allows for uniform contact when released in a groove, accommodating higher thrust loadings compared to constant section or spiral retaining rings. This design also offers a more substantial shoulder to retain components, ensuring stability and reducing the risk of component displacement during operation. The ring's lug holes facilitate easy installation and removal using standard pliers, streamlining maintenance processes and reducing downtime. With a maximum thrust load capacity of 5,024 lbf and a groove safety factor of 2, it ensures reliable performance under significant load conditions. The HO-100ST PA's phosphate finish not only provides corrosion resistance but also serves as an excellent base for additional coatings, offering flexibility for various operational environments. This retaining ring is an essential component for applications requiring secure component retention, high thrust load capacity, and ease of maintenance, contributing to the overall efficiency and longevity of machinery and equipment.
