Good Ball Slewing Bearing With Pinion Gear
The use effect of the slewing bearing and the supporting pinion is the same as that of the slewing drive, but in terms of load bearing, the former is better than the latter. The most common is the application in marine cranes and port cranes.
If the customer needs a faster speed, we still recommend the slewing bearing and supporting gear. The maximum speed of the slewing bearing is 30 rpm, but the maximum speed of the slewing drive is 3 rpm. This is why the matching of slewing bearing and pinion gear is getting more and more popular.
