Why use angular contact ball bearings for ball screws instead of deep groove ball bearings?-From Sanli Robot Technology

Because angular contact ball bearings have higher load capacity, better rigidity, and higher precision!During the operation of a ball screw, it needs to withstand significant axial and radial loads. Angular contact ball bearings can handle these loads, making the transmission system more stable.

In addition, ball screws commonly use precision angular contact ball bearings of P5 and P4 grades, which offer good rotational accuracy and provide accurate motion control and positioning for the screw.

Moreover, angular contact ball bearings have a limited contact angle, resulting in relatively low friction loss, which reduces heat loss and heat generation, improving both efficiency and service life.

As everyone knows, Global top brand bearings are relatively expensive, while China bearings are somewhat cheaper. But can China top bearings replace global top brand bearings in practical applications?

As a manufacturer of angular contact ball bearings with over 40 years of experience, I believe we can.

First, it depends on what equipment they are used in, and then evaluate the speed, load, and temperature requirements of the application scenario.

Unless the operating conditions are extremely harsh, angular contact ball bearings from major domestic manufacturers can meet the application requirements.

Companies looking to replace international famous brand bearings with China top ones are welcome to contact us at any time.
