Flat gearboxes of the "A" series
This model of Austrian gearboxes is extremely compact, in particular with a one-piece output shaft or flange design. At the same time, the gearbox shows good torque performance.
Flat gearboxes, or as they say, mounted gearboxes, because of their shape, can be very compact and at the same time it is a reliable and maintenance–free gearbox with a large number of gear ratios and a high level of efficiency. (efficiency factor). These gearboxes are simply becoming irreplaceable in the industry.
The installation is very simple, the gear motor is put on the shaft of the equipment or inserted by the gearbox into the hollow shaft of the equipment. You can already buy a gear motor with a flange or an output shaft from a gearbox today. A distinctive feature of these gearboxes is their lightness, compactness, high torque and a large number of gear ratios.
Optional forced cooling of the electric motor.
And the special double seals of the output shaft make these flat gear motors especially reliable!
