Custom CNC Machining Motor Stator O-Ring, Precision Metal Sealing Ring

This precision-machined motor stator O-ring is a thin annular sealing component designed for use in motor and mechanical assembly applications. The part features a precise circular profile with a smooth inner and outer diameter, requiring tight control of concentricity, thickness and surface finish to achieve consistent assembly and sealing performance.

CNC machining provides accurate dimensional control and repeatability across the complete ring profile, while precision finishing helps maintain smooth contact surfaces and reliable fit with mating components. We support custom manufacturing based on STEP/IGES files, technical drawings or physical samples, with material and surface treatment options selected according to the application requirements. Prototype, small-batch and mass production are available, and dimensional inspection reports and CMM inspection reports can be supplied for applications requiring high precision, stability and repeatability.
