What is the difference between crossed roller bearings and crossed roller turntable bearings?

Advantages of crossed roller turntable bearing compared with ordinary turntable bearing;

1, the accuracy level of cross roller turntable bearing is much higher than that of ordinary turntable bearing, and the radial runout and axial runout can be much higher than that of ordinary turntable bearing.

2. Cross roller turntable bearing is much more rigid than ordinary turntable bearing, and its running noise is less than cross roller bearing. Therefore, in the low noise working environment, it is best to choose the cross roller turntable bearing.

3. In terms of structure, the cross roller turntable bearing is much simpler than the ordinary turntable bearing. Considerable bearing capacity and overturning moment can be obtained by arranging a row of cylindrical rollers crosswise on a single raceway, while the same effect can be achieved only by arranging three rows of cylindrical rollers on three rows of raceway in turn for ordinary turntable bearings. Compared with the common three-row roller turntable bearing, the cross roller turntable bearing occupies much less space and has much lighter weight.

Structurally speaking, the structure of crossed roller turntable bearing and crossed roller bearing is much simpler than that of traditional bearing. By arranging cylindrical rollers in rows, considerable axial and radial bearing capacity and overturning moment can be obtained, and the structure is much simpler. However, traditional bearings can only achieve the same effect by arranging multiple groups of bearings in sequence, which brings great convenience to design, assembly and installation. Compared with traditional bearings, the cross roller turntable bearing structure and the single row raceway structure of cross roller bearings occupy much less equipment space, and the assembly difficulty is greatly reduced.
