Single row cross roller type slewing bearing, composed of two seat rings, has a compact structure, high manufacturing accuracy, small assembly clearance, and high requirements for installation accuracy. The rollers are arranged in a 1:1 cross arrangement, and can withstand axial forces, overturning moments, and large radial forces at the same time. It is widely used in transportation, engineering machinery, and military products.

1. N is the number of lubricating oil holes. Oil cup M0x 1 JB/T7940.1~JB/T7940.2. Users can specify the position of the oil hole according to the application situation

2. N- φ Can be changed to a threaded hole, with a thread diameter of M and a thread depth of 2M

3. The circumferential force of the gear in the table is the maximum circumferential force, and the rated circumferential force is taken as 1/2 of it

4. The specifications in this sample are standard products, and both the inner and outer diameters have their own tolerances. If there are matching requirements between the main engine and the slewing bearing, please indicate the matching dimensions and accuracy in the contract or contract attachments (such as technical agreements).

5. The products listed in the table are our company's regular products. If you have any other special requirements, please contact our company.

6. The modification coefficients in the table are all designed with external teeth, and the modification coefficients of internal teeth are all 0.35
