Single-sided output shafts
A single-sided output shaft brings torque out of one side of the gearbox or gear motor and connects it to the driven machine. The transfer is direct, which is what keeps it stable and precise, and it suits any drive with a clearly defined working direction. Where the machine takes its drive on one side and needs nothing on the opposite face of the unit, this is the arrangement to specify.
We select the shaft against the loads it carries, the way the drive is mounted and its compatibility with the gearbox series it has to fit. Those three points decide the part, so send the gearbox model, the driven load and the mounting position with your enquiry. We come back with the shaft and a quote within one working day.

Questions about the Output shaft, single series
What is a single-sided output shaft?
It is the output shaft that leaves one side of the gearbox or gear motor and drives the machine directly. Torque goes one way, so the connection is simple to make and the transfer stays stable and precise. It is the normal choice when the machine has one clear working direction and the drive does not have to be split.
Should I use a single-sided or a double-sided shaft?
Use a single-sided shaft when the machine takes the drive on one side only. Use a double-sided shaft when torque has to leave both sides of the unit, for example to turn more than one working element or to split the drive symmetrically. If the layout could go either way, send us a drawing of the machine and we will say which fits.
How do you choose the right shaft?
We look at the loads on the shaft, the mounting method and which gearbox series it has to fit. Those three decide the part we supply, and getting the compatibility right matters as much as the load figure. Send the gearbox model, what the shaft drives and the mounting position with your enquiry and we confirm it.

Accessories
Output flanges FA, FB, FC, FD, FE
Output flanges FA, FB, FC, FD and FE bolt a gearbox or gear motor straight to the machine structure, giving a rigid mount where space is limited.
DiscoverAccessories
Double-sided output shafts
Double-sided output shafts send torque out of both sides of the gearbox, so one drive can turn two working elements. Sized on axial and radial load.
DiscoverAccessories
Torque arms
Torque arms hold the gearbox against the machine structure and take up the reaction force, so a gear motor keeps its position and alignment in use.
