1. Use parts: Tapered roller slewing bearings are suitable for combined loads, usually two sets of slewing bearings are used in pairs, mainly used for transmission parts such as front and rear wheel hubs and reducers of automobiles.

2. Allowable speed: Under normal circumstances, 0.2 times the speed is appropriate.

3. Permissible inclination angle: the tapered roller slewing bearing generally does not allow the shaft to be inclined relative to the housing hole.

4. Allowable temperature: Under normal circumstances, the slewing bearing is allowed to work at an ambient temperature of -30°C-150°C.
