☀Description

The three-row roller slewing ring (13 series slewing ring) has three races, and the upper, lower and radial raceways are separated, so that the load of each row of rollers can be accurately determined. It can bear various loads at the same time. It is the largest bearing capacity of the four products. The shaft and radial dimensions are large, and the structure is firm. It is especially suitable for heavy machinery requiring larger diameters, such as bucket wheel excavators and wheels. Type cranes, ship cranes, port cranes, molten steel running platforms and large-tonnage truck cranes and other machinery.

Note:

1. n1 is the number of lubricating oil holes. Oil cup M10×1JB/T7940.1~JB/T7940.

2. The user can specify the position of the oil hole according to the application.

3. n-φ can be changed to threaded hole, thread diameter M, thread depth 2M

4. The circumferential force of the gear in the table is the maximum circumferential force, and the rated circumferential force is 1/2.

5. "k" is the top cut coefficient.

6. The specifications in this catalog are standard products, and the inner and outer diameters are all with their own tolerances. If the main engine and the slewing ring have matching requirements, please indicate the matching size and accuracy in the contract or contract attachments (such as technical agreements)

7. Listed in the table are our company's regular products, if you have other special requirements, please contact our company.
