Product Overview

Precision C-shaped retaining ring (open-end retaining ring), precision machined and formed, is used as an axial retaining fastener for positioning, anti-detachment, and limiting fixation of shaft assemblies. It is widely used in precision modules, lens assemblies, micro motors, sensors, and other precision assembly scenarios. The open elastic structure allows convenient assembly; after being installed into the groove, it provides stable clamping force and limits axial movement of components.

Product Features

✅ Open elastic design: C-shaped open structure can be slightly expanded for installation; after assembly, it springs back and clamps tightly for reliable retention and easy disassembly. ✅ Precision dimension control: Smooth contour, flat and burr-free cut, uniform thickness, suitable for micro grooves, and stable assembly clearance. ✅ Stable material performance: Made from spring steel / stainless steel base material, with balanced hardness and toughness, and resistant to deformation and breakage after repeated disassembly. ✅ Surface anti-corrosion treatment: Zinc plating, nickel plating, passivation, and other treatments are available; rust-proof and oxidation-resistant, suitable for humid and high/low-temperature working conditions. ✅ Miniaturized adaptation: Supports small inner diameter and ultra-thin specifications, saves assembly space, and is suitable for small precision components such as lenses and micro transmissions. ✅ Retention and anti-detachment: After snapping into the workpiece groove, it blocks axial sliding of parts and reduces the risk of loosening caused by vibration.

Material Options

Spring steel, 304/316 stainless steel; surface treatment: zinc plating, nickel plating, passivation, blackening (customized as needed)
