What Are The Different Types Of Bearings Used In Power Machine Tools?

According to historical data, humans used machine tools to make ceramic bowls, vases, plates, and other items. The earlier forms of machine tools were simple in design and used plain bearings and linear guides.

However, with the advancement of machine tool technology, the components are enhanced to improve their alignment and accuracy. Plain bearings are replaced by rolling-element bearings that reduce the sliding friction between the moving parts.

What Are The Main Bearings Used In Machine Tools?

Using high-precision bearings is crucial to maintaining the machine’s accuracy and reliability. The bearing tools are responsible for directing and enhancing the spindle movement. The bearing unit comprises balls or rollers that are placed between the inner and outer raceways.

Common Types of Bearings-

1. High Precision Cylindrical Roller Bearings

These bearings use cylinders as rolling elements and are available in single—or double-row designs. The high-precision bearings are made to handle large radial loads and are best for high-speed applications that need an accurate bearing-spindle arrangement.

2. Ceramic Hybrid Spindle Bearings

The ceramic hybrid spindle bearing offers increased spindle speed, improved stiffness, and enhanced resistance. The ceramic balls used in these bearings work best at low temperatures, extending the life of the lubricants. These bearings are best suited for operating at low vibration levels.

3. Angular Contact Bearings

An angular contact ball bearing has inner and outer raceways accommodating radial and axial loads. The bearing’s axial load capacity increases as the contact angle increases.

4. Ball Screw Support Bearings

Ball screw support bearings allow an accurate positioning of machine components. These bearings are available in high-rigidity and high-capacity series. Each one of them is designed for any application they support. Their design allows them to handle large axial loads.

Machine tools are too complex and need specialised power bearings for increased performance, accuracy, and speed. Maintaining the bearings is crucial to maximising their life and performance.
