Positions even the heaviest loads with high precision

We have developed the RS series especially for positioning heavy loads. These precision gearboxes with hollow shaft have an integrated angular gearbox and a stable, durable design.

Reliable, precise positioning of heavy loads, hollow shaft (for feeding through cables etc.)

Main bearing allows axial loads of up to 1.5 t (RS-50A), 2.5 t (RS-260A), 5 t (RS-320A), 7 t (RS-400A) or up to 9 t (RS-900A)

Low wear - Cast iron base for stable floor mounting. Easily accessible motor mounted at a right angle.

Designed for axial loads of up to nine tons

The high-precision RS series gearboxes with integrated angular gearbox are designed for axial loads of up to 9 tons. A cast-iron base ensures stable, hard-wearing floor mounting. The motor is mounted at a right angle and is therefore easily accessible. With this compact design and its exceptional power, the hollow shaft gearboxes of the RS series are clearly superior to conventional camshaft and worm gearboxes.

The hollow shaft makes it easy to feed through supply lines and cables. In addition, these precision gearboxes operate virtually backlash-free. This makes the RS series suitable for a wide range of demanding applications such as machine tools, welding table positioning and rotary indexers as well as large robots.
