Cross bearings compared to normal bearings
Jan 15, 2019

Standard joint bearings are generally used for low-speed swing or rotary motion. Since the sliding surface is spherical, it can also be tilted within a certain angle range with enables the shaft works well even when the support shaft and the bearing holes are not centered. In some applications, where the angle of inclination is greater than 15°, the joint bearing cannot meet the requirements, in these cases, a different type of cross bearing is developed to replace the standard joint bearing.


This is a cross-bearing that can withstand radial loads, axial loads or combined loads and has a larger angle of deflection than standard joint bearings. The utility model comprises a swinging block, wherein the two swinging shafts are respectively arranged on the support of the two sides of the swinging block, and the two swinging shafts are respectively mounted on the support, and the first axial hole perpendicular to the swinging shaft is opened inside the swinging block. A spindle is mounted in the first shaft hole, and a second shaft hole is formed on the circumferential surface of the spindle. A third shaft hole having a larger diameter than the second shaft hole is formed in the swing block corresponding to the position of the second shaft hole.


The cross bearing has a simple structure and is easy to assemble. With the large angle swing of the swing block and the large angle rotation of the mandrel, it has a larger inclination angle than the standard joint bearing, and the inclination angle can be more than 45°, which is much larger than the existing standard joint
