Model Number: SE3-62-H-16R Brand Name: Wanda Key Specifications/Special Features: WandaSlewing bearing company limited is professional manufacturer and exporter of slewing bearing, slewing drives, which are mainly applied in port machinery, mining machinery, welding machinery, construction vehicles, modular vehicles, single or dual axis solar tracking systems and small wind power systemsSlewing bearing/drives can bear axial force, radial force and tilting momentDiameter range of slewng bearing can be from 200mm to 5000mm for slewing drive, there are nine (9) different sizes available from 3" to 25" with more than 60 models to meet both regular and precise tracking requirements in PV, CPV and solar thermal power tracking fieldsFor detailed information please download our catalogueSlewing drive:By adapting slewing bearing as its core component, slewing drive can bear axial force, radial force and tilting moment simultaneously
Slewing drive is widely applied in modular trailers, all types of cranes, aerial working platform, solar tracking systems and wind power systems
Electric and planetary gearboxes can be designed according to customer's requirement
Slewing drive has the advantage for saving space in facilities, max load capacity in a compact design, extensive lifespan, reduced maintenance costs

Glossary
Tilting moment torque: torque is the load multiplied by distance between the position of load and the center of slewing bearing
If the torque generated by load and distance is greater than the rated tilting moment torque, slewing drive will be overturned
Radial load: load vertical to the axis of slewing bearing
Axial load: load parallel to the axis of slewing bearing
Holding torque: reverse torque
When the drive is rotating reversely, and parts are not damaged, maximum torque achieved is called holding torque
Self-locking: only when loaded, the slewing drive is not able to reverse rotate and thus called self-locking

Hourglass worm:
Hourglass worm: compare with traditional worm, hourglass worm can withstand a survivability load that is four to nine times greater
As the special hourglass shape of the drive allows more teeth to be engaged at one time, enabling much higher torque endurance
Can increase the durability, precision and efficiency and maximum load capacity in a compact design
