Power through Efficiency

Gearboxes

SAI has a range of custom made gearboxes that have been specifically designed to suit and be coupled to the SAI range of Radial Piston Hydraulic Motors.

These high efficiency units offers great compactness and flexibitity and the gearboxes can be lubricated by the same hydraulic oil that lubricates the motor crankcase. By fitting single, dual or variable motors to these gearboxes, drives can therefore have fixed, dual or variable effective displacements (motor displacement x gearbox ratio).
