Shaft Mounted Gearboxes

We offer shaft mounted gearboxes for many applications and industries. For example conveying, screening, quarrying, Biogas etc. In addition, we have various styles of shaft mount gearboxes including parallel shaft, right angle and planetary geared units. These units are suitable for direct mounting onto the shaft of the driven equipment. We do this by offering a range of output fixing styles for shaft mount gearboxes, which include bore and key, shrink disc, and our ‘Quick Lock Bush System’. As a result of having these methods we can offer a variety of option bore sizes.

Our shaft mount gearbox can be adapted to suit our customers shaft sizes. Shaft mount gearboxes also remove the need for couplings and mounting plinths and are extremely easy to fit.
