Advantage:
S-2 Slewing drive is combined by the S style housing, slewing bearing, hourglass worm gears and other parts. It achieved 2 times of tooth contacting. In the same volume and installation space, it improved nearly double output torque and holding torque , this series slewing drive are widely used for the heavy-duty machines.

Feature
1) FRB S-2 series designing with two hourglass worms, it is improved double output torque than S series
2) FRB S-2 Series slewing drive designing with two worms driving at the same time. It is double tooth contacting, Performance better than S series, better rigidity and double impact resistance.

Application:
S-2 series slewing drives widely used for relative rotation parts of the construction machines.
1)Driving Digger drilling machine azimuth & Elevation rotation.
2)Controlling the rope winder machine console rotation.
3)Grappling's rotation parts.
