In the process of slewing bearing use, it will endure 3 different direction force, including the axial force Fa, the radial force Fr and the overturning moment M. The combination of the three loads will change as a result of different working ways and different structural types in different practical applications, sometimes it may be bear two loads, sometimes there is just one load. This requires the slewing bearings to have high stability of quality, SWBTEC slew bearing, from raceway hardening to gear hard treatment, we strive to excellence.

Cross Roller Slew Bearing is with rolling elements in a 90°cross arrangement at a ration of 1:1. Due to the roller transmit load in a single direction, and the contact area of roller is bigger than the ball, so the rotational torque is less than a ball type design, it can provide higher rigidity and strength. Although the crossed roller slew bearing is with less load capacity than ball type when with same size rolling elements, but crossed roller type bearing has higher stability. SWBTEC can produce different size crossed roller slewing bearing with dimension from 100mm-2500mm and often prepare stock for popular model.

High Precision Cross Roller Slewing Bearing can bear axial, radial and tilting moment load from different directions due to the roller inside is arranged vertically and in a 90°V groove. This design can minimum the dimensions of inner ring and outer rings and make the bearing with high rigidity and high precision which can reach to P5, P4, P2, so it is the optimal choice for applications such as industrial robot, rotator, precision rotary table, medical equipment and military equipment.
