Toothless type 6.3.3 Structural parameters of single-row crossed roller type Structural features, performance, scope of application High degree of accuracy, small assembly gap, single-row crossed roller slewing bearing, composed of two races, compact structure, light weight, accurate radial force production, widely used for high installation accuracy requirements, rollers are arranged in a 1:1 cross, can withstand axial force, overturning moment and large at the same time. Used for lifting and transportation, engineering machinery and military products

Note 1. n1 is the number of lubricating oil holes. Steel ball diameter < medium 25 oil cup M8x1 (JB/T7940.1~JB/T7940.2); steel ball diameter > medium 25 oil cup M10x1 (JB/T7940.1~JB/T7940.2). The user can specify the oil hole location according to the application. 2. The thread diameter in n can be changed to M, the thread depth is 2M3, the circumferential force of the gear in the table is the maximum circumferential force, the rated circumferential force is 1/24, and "K" is the peaking coefficient. 5. The specifications in this sample are standard products, and the inner and outer diameters are all within free tolerance. If the host machine and the slewing bearing have matching requirements, please indicate the matching dimensions and accuracy in the contract or contract attachments (such as technical agreement). 6. The products listed in the table are our company’s regular products. If you have other special requirements, please contact our company.
