Motovario MHD Gearbox

The Motovario heavy-duty gearbox range consists of three product types, which are designed to ensure that every application can be catered for, whilst meeting the needs of specific budgets.


The three series are readily available in multiple sizes and configurations as a bevel helical reducer or alternatively a parallel helical, with a variety of options in terms of extra accessories available.


The MHD series can produce anything up to 110,000Nm output torque with cases manufactured using cast iron. To allow for a range of speeds to be achieved to meet specific customer demands, each series has an extensive list of ratios that can be achieved to ensure all applications can find a solution.

The Motovario medium heavy-duty gearboxes are supplied with a two-year manufacturer’s warranty, ensuring that customers are confident their applications will always be functioning.
