In the field of modern manufacturing equipment and precision machinery, the spindle system is regarded as a "heart" component, and its performance directly determines the machining accuracy, efficiency and equipment stability. As the key supporting element in the spindle system, the technical progress of sliding bearing not only changes the bearing and lubrication mode, but also plays an important role in improving the overall performance of the spindle.

First, the importance of sliding bearing in spindle system

Supporting and guiding function: Sliding bearing provides stable support for the spindle, making it maintain accurate axis trajectory under high-speed rotation.

Reduce vibration and noise: Reasonable lubrication and structural design can effectively reduce running friction, thus reducing vibration and noise.

Strong bearing capacity: Sliding bearing has more advantages in heavy load and long-term operation, especially suitable for heavy load and high-speed working conditions.

Second, the key changes brought about by technological progress

High precision manufacturing process

Modern sliding bearing adopts NC machining, laser measurement and surface finishing technology, which significantly improves the geometric accuracy and surface quality of the bearing, thus reducing the spindle deflection and improving the rotation accuracy.
