Spindle Bearings

The Spindle bearings produced by CHG can be divided into 4 series: 618 series、619 series、718 series、719 series. With the inner diameter range from 100mm to 950mm, and the precision is divided into P6, P5, P4 and P2. The bearings are available in open and sealed versions.
Spindle bearings have restricted tolerances. They are particularly suitable for bearing with very high requirements for guidance accuracy and speed capacity. They have proved highly suitable for the bearing of spindles in machine tools.

What are Spindle Bearings?

Spindle bearings are a crucial component in various types of machinery, particularly in applications requiring high precision and reliability. These bearings are designed to handle high speeds, loads, and radial forces, making them ideal for use in spindles of machine tools, high-speed motors, and other demanding applications. Their superior design and construction allow them to support the rotational movement and stability of the spindle, ensuring smooth operation and extending the machine's overall lifespan.
