Double-sided output shafts
A double-sided output shaft takes torque out of both sides of the gearbox or gear motor. One drive can then turn more than one working element, or feed a more involved drive layout, with the torque transfer staying stable and continuous on both sides. Machines that split the drive symmetrically, or that work on more than one side at once, are the usual reason for specifying this shaft rather than a single-sided one.
Axial and radial loads decide the part here, so we work through them with you before confirming the shaft and the gearbox it fits. Send the gearbox model, what each side drives and the mounting position, and we quote within one working day.

Questions about the Output shaft, double series
What is a double-sided output shaft for?
It gives you a drive output on both sides of the gearbox instead of one. That is what lets a single unit turn more than one working element, or lets you build a more involved drive layout around one gearbox. It is also the shaft to use when the machine needs the drive split symmetrically across it.
Can both sides drive at the same time?
Yes. The shaft carries torque out of both sides of the unit, which is how one gearbox feeds two working elements or splits the drive evenly across a machine. Transfer stays stable and continuous on both sides while the machine runs. Tell us what each side drives so we can check the loads before we confirm the part.
What do you need to size one?
We start from the axial and radial loads on the shaft, since those govern the choice on a double-sided arrangement. Then the gearbox series it has to fit and the way the drive is mounted. Send the gearbox model and what each side of the shaft drives, and we confirm the shaft with the quote.

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.

Single-sided output shafts
Single-sided output shafts take the torque from one side of the gearbox and pass it straight to the driven machine. Sized on load and mounting method.

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.
