Slewing bearings
Slewing bearings are widely used in real industry and are called “joints of machines”
It is mainly used in:
Truck cranes, railway cranes, port cranes, marine cranes, metallurgical cranes, container cranes, excavators, filling machines, and CT standing wave therapy devices, navigation instruments
Radar antenna mounts, missile launchers, tanks, robots, and revolving restaurants.

Slewing ball bearings are required to work under low speed or discontinuous operation conditions, and most of them operate under eccentric loads. In addition to bearing axial loads and radial loads, they must also withstand overturning moments. The grade of slew plate bearings, according to the frequency of use of slew plate bearings, the standard number of working cycles of slew plate bearings are classified as follows:
Standard working cycle classification of slewing bearings
When users use slew plate bearings, please consult the technical service department for an estimate of the allowable contact stress of the slew plate bearing, the load-bearing capacity and service life of the slew plate bearing.
| The frequency of use of slewing bearings | Standard working cycle number Lc | Slewing bearing usage grade |
| Occasional use, long periods of inactivity | 0.063×106 | A |
| Regular use, but not concentrated use | 0.2×106 | B |
| Centralized operation and regular use | 0.063×106 | C |
| Centralized operation of multiple shifts and regular use | 2×106 | D |
When installing the slew bearing, the bolts should have sufficient prestress, and try to use grade 8.8, 10.9 or 12.9 bolts to ensure reliable work.
