Alloy steel, hardened carbon steel, heat-treated stainless steel. High tensile strength, high-temperature resistance, and resistance to deformation and fracture. [E-type structure]: E-type three-jaw design, with three points of contact at the bottom of the groove. Provides a larger clamping area, effectively securing components subject to axial movement. [Installation Method]: Can be inserted or removed from the side without the need for shaft movement tools. Suitable for installation using tools or by hand. [Performance]: The concave design provides spring-loaded locking. Prevents loosening caused by high-speed rotation or rapid movement. [Precautions]: Before purchasing, ensure that the shaft diameter or bore diameter matches the retaining ring specifications. During installation, ensure that the retaining ring is fully seated in the groove., Manufacturer: AURVIX
