Custom High-Precision CNC Bearing Housings & Flange Assemblies – Core Support Solutions for Industrial Transmission

Product Overview
We provide comprehensive, one-stop customization services for high-end precision bearing housings and transmission flange mounts. Utilizing advanced turn-mill machining technology, we specialize in crafting critical support components for the semiconductor, automation, and precision machinery industries.

Whether the requirement calls for the high strength and corrosion resistance of stainless steel or the lightweight design of aluminum alloys, we ensure that every bearing housing maintains exceptional concentricity and repeatable positioning accuracy, even under high-speed operating conditions.

Core Technical Advantages

Micron-Level Tolerance Control for Bearing Seats
The tolerance of the bearing seat directly impacts the service life of the equipment. Through precision CNC boring and grinding processes, we consistently maintain internal bore tolerances within the H7–H8 range, ensuring a precise interference fit during bearing installation and effectively eliminating vibration and noise.

Multi-Axis Turn-Mill Machining: Single-Setup Forming
Leveraging multi-axis simultaneous control technology, we complete the machining of complex stepped bores, countersunk holes, and U-grooves in a single clamping setup. This fundamentally eliminates the coaxiality errors typically associated with multiple setups, guaranteeing perfect perpendicularity between the flange face and the shaft axis.

Materials and Surface Treatments for Harsh Environments
We support a wide range of materials, including SUS304/316L stainless steel, aerospace-grade aluminum alloys, and copper alloys. We offer various surface treatments—such as hard anodizing, electropolishing, and electroless nickel plating—to significantly enhance the components' wear resistance and chemical stability.

100% Digital Inspection and Traceability
Every product batch undergoes rigorous inspection using a Coordinate Measuring Machine (CMM) to verify concentricity and positional accuracy. We provide comprehensive Material Test Reports (MTRs) and dimensional inspection data, ensuring a 100% assembly yield rate.
