Due to Four point contact ball slewing bearing having the widest application, it is our main product and accounts for 80% of the total product, In order to make sure the contact angle is within the right point, we constantly inspect the raceway grinding machine and inspect the contact angle with a special tool which is our practical patent, this is also why our delivery swinging ball bearings have a longer life than other peers.
Features and Benefits of SWBTEC's Four Point Contact Ball Slewing Bearing
The size of the four point contact ball slewing ring
size usually is large with diameter 250~1800mm meters Therefore, a set of slewing bearing often plays the role of several sets of ordinary rolling bearings, that is why it become more and more popular in modern industry
The rotate speed of the slewing bearing is very low, usually below 10 rpm. In addition, in most cases, the slewing bearing does not rotate continuously, but only rotates back and forth within a certain angle, which is equivalent to the so-called "swing bearing".
Usually, the slewing bearing is equipped with a gear ring for rotary drive and seal for dust prevention.
Advantages Of Single Row Ball Slewing Bearing:
1. Small size with compact structure;
2. Light in weight;
3. Can load axial, radial, meanwhile also tilting moment.
