What is the difference between cross roller linear bearing and cross roller turntable bearing?

Advantages of cross roller turntable bearing over ordinary turntable bearing:

1. The accuracy level that cross roller turntable bearings can achieve is much higher than that of ordinary turntable bearings, and the radial runout and axial runout that can be achieved are much higher than that of ordinary turntable bearings.

2. The rigidity of cross roller turntable bearings is much greater than that of ordinary turntable bearings, and the running noise is smaller than that of cross roller bearings. Therefore, in a low noise working environment, it is better to choose cross roller turntable bearings.

3. In terms of structure, compared with ordinary turntable bearings, cross roller bearing structure is relatively simple. Through a row of cross-arranged cylindrical rollers on a single raceway, considerable bearing direction, radial bearing capacity and overturning moment can be obtained, while ordinary turntable bearings must be sequentially arranged on three rows of cylindrical rollers on three rows of raceway. To achieve the same effect. In this way, the cross roller bearing takes up much less space and is lighter than the ordinary three row roller bearing.

In terms of structure, the structure of cross roller turntable bearings and cross roller bearings is much simpler than that of traditional bearings. Through the multi-row arrangement of cylindrical rolling bodies, considerable axial and radial bearing capacity and overturning moment can be obtained, and the structure is much simpler, while the traditional bearings must be arranged through multiple sets of bearings in order to achieve the same effect. This brings great convenience in design and assembly and installation. Compared with traditional bearings, cross roller turntable bearing structure and single row raceway structure of cross roller bearing occupy much less space of equipment and greatly reduce the difficulty of assembly.
