Suzhou Krosino Mechatronic Technology Co., Ltd. provides advanced CNC machining and finishing for precision bearing housings, races, and specialized bearing-integrated components. High-performance bearings rely on sub-micron geometric accuracy and superior surface integrity. We specialize in producing custom bearing-related components that minimize friction, reduce heat generation, and ensure smooth rotation for your demanding mechanical assemblies.
Bearing components demand extreme dimensional stability and perfect concentricity. We apply rigorous machining techniques to ensure all functional surfaces meet the high-speed operational requirements of industrial machinery.
| Feature Application | Typical Functional Tolerance |
|---|---|
| Bearing Race Bores | ±0.005mm to ±0.01mm (Critical fit control) |
| Concentricity / Circularity | 0.005mm TIR (Minimizes vibration) |
| Surface Roughness (Ra) | 0.2μm to 0.4μm (Ensures longevity and low friction) |
Q1: How do you achieve the tight tolerances needed for bearing fits?
We utilize precision CNC turning and boring centers with thermal compensation. By controlling environmental temperature and using specialized high-stiffness tooling, we maintain stable dimensions at the micron level, ensuring your bearings seat correctly every time.
Q2: What materials do you use for high-load bearing parts?
We work with high-grade bearing steels (like GCr15) and hardened alloy steels. These materials are chosen for their excellent fatigue life, dimensional stability, and wear resistance under continuous operational stress.
Q3: How do you ensure surface finish quality for rolling surfaces?
Following precise CNC milling or turning, we employ specialized grinding and polishing techniques to achieve the low Ra values necessary to prevent early fatigue and optimize lubrication film formation between the bearing and its housing.
