RS
Gearheads with hollow shaft

Positions even the heaviest loads with high precision

The RS series was developed especially for the positioning of heavy loads. These gear heads with hollow shaft have an integrated bevel gear and a stable, durable construction.

Reliable, exact positioning of heavy loads, hollow shaft (for the passage of cables etc.)

 

 

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

 

 

Cast-iron base for stable floor mounting Easily accessible, right angle motor

 

 

Designed for axial loads up to nine tons

The high-precision Trochoid gear units of the RS series with integrated angular gearbox are designed for axial loads of up to 9 t. A cast-iron base ensures a stable, durable floor mounting. The motor is mounted at right angles and is thus easily accessible. With its compact design and exceptional power, the RS series hollow shaft gearboxes are far superior to conventional camshaft and worm gearboxes.

The hollow shaft makes it easy to perform supply lines and cables. In addition, these gear heads work almost free of play. This makes the RS series suitable for a wide range of demanding applications such as machine tools, welding table positioning and turntables as well as large robots.
