Dentail

Structural Features

Type: It is a single-row angular contact ball bearing, suitable for withstanding radial and unidirectional axial loads.
Material: It adopts ceramic balls (hybrid bearing). Compared with all-steel bearings, it has lower mass, higher hardness, and better wear resistance. It can reduce friction and heat generation, and improve the rotational speed capacity.
Tolerance class: P4S (ultra-precision class), which ensures high rotational accuracy and rigidity.
Cage: It has good wear resistance and high-speed stability.
Lubrication design: DLR indicates a direct lubrication structure, which optimizes the lubrication efficiency and is suitable for high-speed working conditions.

Performance Advantages

High-speed performance: The ceramic balls reduce the centrifugal force and heat generation, and the limiting rotational speed is significantly higher than that of ordinary steel ball bearings.
High precision and rigidity: The P4S tolerance class and angular contact design provide excellent guiding accuracy and anti-deformation ability.
Long service life: It has excellent corrosion resistance and fatigue resistance, and is suitable for harsh environments.

Application

The bearings can be used in the following industries

Machine tool spindles: Such as high-speed machining centers and precision grinders, which require high rotational speed and high-precision support.
Semiconductor equipment: Such as lithography machines and wafer cutters, which require low vibration and high reliability.
Medical devices: Such as CT scanners and dental equipment, which require quiet and low-heat precision transmission.
High-speed motors: High-frequency motors and turbomachinery, which need to withstand high rotational speed and dynamic loads.
Precision instruments: Centrifuges and testing equipment, which rely on the stability and precision of the bearings.
