Features of Slewing Gear

Slewing gearbox is mainly used for turning gear ring and large-diameter wear-resistant slewing bearing. For example, cranes have been proved to be under the worst application conditions. The rotary gearbox is based on a modular design and has a larger delivery range (motor, coupling, brake). In each application, the pinion rotary ring tooth pairing is checked, and the tooth shape of the pinion is optimized to ensure a long service .life
The advantage is

  • compact size
  •  long service life
  •  modular design of gear unit
  • easy to maintain
  •  high performance
  •  functional design

With these features, machine designers will Be ready to install the device and realize economic benefits.
Solutions can be found even in confined space conditions.
