The Key Bearings for Machine Tools
High-quality precision bearings are particularly important for the precision and reliability of machining machines, as they are responsible for guiding and enhancing spindle movements. These typically consist of balls or rollers located between the inner and outer raceways. Some of the most common types of bearings include：
- High precision cylindrical roller bearings. Cylindrical roller bearings use a cylinder as the rolling element and are usually available in single or double row designs. These bearings are constructed to withstand large radial loads and are ideally suited to high speed applications requiring high operational accuracy in a bearing-spindle configuration.
- Ceramic hybrid spindle bearings. Ceramic hybrid spindle bearings offer higher spindle speeds, higher stiffness and greater resistance to high temperatures. The ceramic balls used in these bearings operate at lower temperatures, resulting in longer lubricant life. They can also operate at lower vibration levels, resulting in increased spindle stiffness.
- Angular contact bearings. Angular contact ball bearings have inner and outer raceways that are offset relative to each other in the axial direction, allowing them to carry combined radial and axial loads at the same time. The axial load capacity of these bearings increases as the contact angle becomes larger. The contact angle is the angle between the line connecting the two points in the radial plane where the steel ball is in contact with the raceway.We can supply mini lathe angular contact bearings
- Ball screw support bearings. Ball screw support bearings allow precise positioning of workpieces or machine components. These bearings are typically available in a high rigidity and high capacity range, each specifically designed for the application they support. Their specialised geometry allows them to handle large axial loads in both directions.

What Are the Applications of Machine Tool Bearings?
Machine tool bearings are designed with unique geometries, features and materials that make them suitable for specific machining purposes. Expected load pressures, temperature fluctuations, exposure to chemicals and other factors will influence which type of bearing is best suited to a particular application. Ball and roller bearings are among the most versatile bearing types and they are used in everything from turbine engines to medical equipment. Roller bearings use a variety of rolling element shapes, including ball, cylindrical roller, tapered roller, needle roller, spherical roller and straight roller. Bearings with seats consist of ball, roller or sleeve bearings mounted in a housing that provides additional support and environmental protection. Specific machine tool bearing applications include:
- Machining centers
- Automatic screw machines
- Grinding machines
- High speed spindles
- Rotary tables
- Live and dead centers
- Water jet machines
