It features compact in design, light in weight, high precision and small fitting clearance. As the rollers are 1:1 cross arranged, it is suitable for high precision mounting and capable to bear axial force、tipping moment and considerable large radial force. The single – row cross roller slewing bearings are widely used for hoisting. Transporting、 engineering machines as for military products.型号表示方法：型号表示方法：单排交叉滚柱（锥）式回转支承型式（单排交叉滚柱（锥）式回转支承型式（JW 系列）系列）1、、按齿轮传动方式分为：按齿轮传动方式分为：a. W－外齿式；－外齿式；b. N－内齿式；－内齿式；c. U－无齿式。
