Ultra-Precision Angular Contact Ball Bearings & High-Speed Deep Groove Ball Bearings

1. High-Speed Performance: QIBR’s angular contact ball bearings are designed with an optimized contact angle between the rolling elements and the inner and outer rings, allowing them to handle both radial and axial loads at high speeds.

High-Speed Deep Groove Ball Bearings: Made from high-quality steel and precision-machined, these bearings ensure high-speed performance while maintaining low noise and vibration levels.

2. High Rigidity: Angular Contact Ball Bearings: Designed with preload, these bearings offer significantly increased rigidity, reducing displacement caused by load variations during operation.

Deep Groove Ball Bearings: The deep groove design provides a large contact area, allowing the rolling elements to better handle radial and axial loads. This large contact area helps distribute the load, reducing deformation and improving rigidity.

3. High Precision: Ultra-Precision Angular Contact Ball Bearings: With precision up to P4 grade, QIBR’s angular contact ball bearings meet the stringent accuracy requirements of high-speed CNC machine tool spindles.

High-Speed Deep Groove Ball Bearings: These bearings achieve P2 grade precision, providing excellent rotational accuracy while ensuring high-speed performance.
