Specifications
Dalian United Wind Power Generation Bearing Co.,Ltd.(UWE bearing),registered trade mark ‘UWE’, is located in Xijiao industry park of Wafangdian, Dalian-the capital of the bearings, covers an area of 50,000 square meters. With a registered capital of 20 million Yuan (RMB) and total capital of more than 250 million Yuan (RMB), UWE bearing has strong comprehensive competitiveness with constructed 20,000 square meters of workshop,over 100 employees,boast an annual sales figure that exceed 150 million Yuan (RMB).
UWE Cross roller bearing,because of its vertical arrangement of cylindrical roller with a 90°V groove through the separate spacers in the deep groove rolling surface. This design allows just one bearing to receive loads in all directions including radial, axial and moment load.
At the same time, cross roller bearing is a light weight, compact type with thinnest possible inner and outer rings, especially for the thinnest, with high rigidity.
The spacers fitting among cross arranged rollers prevents rollers from skewing and the rotation torque from increasing due to friction between rollers. The spaces keeps rollers in their proper position, thereby preventing them from skewing. It does nor cause unilateral contact of roller or locked rollers. Since the inner and outer rings are designed to be separable, the bearing clearance can be adjusted, in addition, a preload can be applied. These features enable accurate rotation.
The inner and outer rings, which are separable, are secured to the body after being installed with rollers and spacers. Therefore, it is easy to handle the rings when installing the cross roller bearing.
