Crossed Roller Bearings for Robots
With the development of electronic technology, computer technology, numerical control and robotics technology, automatic welding and cutting robots have many advantages such as stable welding and cutting quality, high productivity, and shortened product remodeling cycles. The technology has become increasingly mature and has been used in various industries. However, welding and cutting robots have high requirements for accuracy and reliability. Accordingly, the bearings of each joint are also required to have high precision, high rigidity, and good friction torque stability. The RB series and RU series cross roller bearings developed by Tedin for this type of industrial robot joints have the advantages of small structural size, high precision, small friction torque, and good preload rigidity. They are widely used for the three-axis and four-axis joints of this type of robots.


TEDIN's RU series, RB series, and RA series high-rigidity crossed roller bearings are suitable for the three-axis and five-axis joints of welding and cutting industrial robots.
Typical case:
Three-axis joint for welding robot: RU148 UP5 X crossed roller bearing;
Five-axis joint: RB6013AUUCCOP4 crossed roller bearing.
Model:
RU series crossed roller bearings
RB series crossed roller bearings
RA series crossed roller bearings
