Large Cross Roller Slewing Bearing with internal Gear

General introduction:

On the basis of the cross roller slewing bearing, many cross roller turntable bearings with different structures have been derived, so that they can be used in different situations with different requirements. It can be divided into: basic cross roller turntable bearing, high rigidity cross roller slewing bearing, ultra-thin cross roller turntable bearing; From the external structure, there are inner ring split type, outer ring split type, and inner and outer ring integrated type; From the internal structure, it can also be divided into full loaded roller type, metal window type cage type, nylon or metal isolation block type; According to the connection mode, there are various types, such as bolt connection type, rivet connection type and spring disc type.

Gear type of large cross roller slewing bearing

1. External gear

2. Internal gear

3. Gearless

All the gear teeth can be hardened, hardness is HRC45-55

Main advantages of cross roller turntable bearing:

1. the structure of the cross roller turntable bearing is relatively simple. Through a row of cylindrical rolling elements arranged in a single raceway, a considerable axial and radial bearing capacity and overturning moment can be obtained.

2. the cross roller turntable bearing will not have the phenomenon of one-side contact or locking of the rollers. At the same time, because the inner and outer rings of the standard cross roller turntable bearing are divided, the gap can be adjusted, and even if the preload is applied, the high-precision rotation movement can be achieved.
