The Linear Optical Axis Retaining Ring is an annular elastic component used in mechanical transmission systems to achieve axial positioning and fixation of components on the axis. It is usually mounted in the circular groove on the optical axis, and fixes itself on the groove wall through its elastic tension to prevent axial movement (left-right displacement) of components such as gears, bearings, and pulleys on the axis, thereby ensuring the stability and reliability of the mechanical structure.
product highlights
Flexible positioning, easy installation, continuous improvement, advanced technology
Precision Machining for Accurate Positioning
The shaft retaining ring undergoes CNC precision machining, with tolerance controlled within ±0.02mm. It fits perfectly with the shaft/hole surface, effectively preventing axial movement.
High-Strength Material for Harsh Environments
Made of aluminum alloy or stainless steel (304/316), and processed through quenching and tempering treatment, it reaches a hardness of HRC 42-48, suitable for high-load and vibrating environments.
Easy Installation for Improved Efficiency
No additional tools are required. The elastic opening design allows direct embedding into the groove, increasing installation efficiency by 50%.
Professional
The surface is treated with zinc (Zn) plating, nickel (Ni) plating, or black oxide treatment. It passes over 100 hours of salt spray testing and can adapt to harsh environments such as humidity, dust, and acid-alkali conditions.
Product parameter information
