The Rotor Clip CG-100ST OIL External Spiral Retaining Ring is engineered to provide secure and reliable retention in applications requiring precise clamping and positioning. Designed for external installation on shafts with a 1" diameter, this retaining ring features a 0.94" groove diameter, ensuring a snug fit that effectively holds components in place. Manufactured from high-quality SAE 1060-1090 steel, it offers exceptional strength and durability, capable of withstanding demanding operational conditions. The oil-coated finish enhances lubricity, facilitating smooth operation and reducing friction between mating surfaces. This feature is particularly beneficial in automotive engineering, hydraulics, and general machining applications, where consistent clamping force is essential. The oil coating also simplifies installation and removal processes, contributing to operational efficiency. With a free diameter tolerance of -0.0130 to 0.0000 inches and a groove depth tolerance of -0.0040 to 0.0040 inches, the CG-100ST OIL ensures precise fitment, minimizing the risk of component slippage or deformation. Its robust design and high-quality materials make it a reliable choice for industries demanding high precision and durability in their fastening solutions.
