Motovario Helical Bevel Gear Reducers

The Motovario cast iron B series Helical bevel gearboxes provide exceptional functioning performance for a variety of industrial and civil applications ranging anywhere up to 100mm hollow bore size.

The B series offers a range of bore sizes from 20mm to 100mm output shaft, with a large variety of inputs available, and can be mounted in several different positions to suit the customer’s requirements. An extension to this would be the BA series which is a smaller aluminium version that can be used as an alternative to the Motovario worm range, with a bore size of up to 35mm.

Motovario B Series can offer an output torque of up to 13000NM and a motor input power of up to 90kW, allowing for the most demanding of applications to be driven. B series can offer a 3-stage reduction allowing for ratios anywhere between 5,71:1 and 187,24:1, giving customers a large range to suit specific application requirements.

To give customers a sense of confidence in Motovario, a two-year warranty period is supplied with all bevel helical gearboxes from the manufacturer.
