Bearing surfaces are precision-machined contact areas on spindle components that support rotational motion with minimal friction and wear.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Hardness | 58-65 HRC | |
| Cylindricity | ≤ 3 μm | |
| Surface Finish | Ground or superfinished | |
| Surface Roughness | Ra 0.1-0.4 μm | |
| Roundness Tolerance | ≤ 2 μm |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.

CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Manufacturer profiles associated with Bearing Surfaces.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Premature wear typically results from improper lubrication, contamination (dust/chips), misalignment, excessive loads, or suboptimal surface finish.
Inspect during routine maintenance (every 500-1000 operating hours) using precision measuring tools to check for wear, scoring, or loss of tolerance.
