The Reduction gears can be used in conjunction with the direct drive drilling unit B050D. The gears are accessories. The installation can be done in the factory and also afterwards at the customer. The use of the gear allows the reduction of speeds while maintaining the drive capacity of the motor and increases the torque of the drilling spindle.
The reduction gears are optional and can also be used in combination with a hydraulic feed control.
The drilling units of type B050A don’t need the reduction gear to achieve the desired spindle speed, because the speeds can be achieved by using appropriate belt drives.
