RS


Rotary indexer with hollow shaft

Positions even the heaviest loads with high precision

The RS series was developed especially for the positioning of heavy loads. These rotary indexer 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 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)

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

Designed for axial loads up to nine tons

The high-precision 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 rotary indexers work with virtually no backlash. 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.

Areas of application of RS rotary indexers with hollow shaft

Robotics

Delta, SCARA and 6-axis robots for painting systems, assembly, PCBs and machine tools

Machine tool building

Magazine drives and handling of very large loads

Antenna construction

Adjustment of large parabolic antennas for communication with near-Earth satellites

Welding

Positioners and rotary tables for the precise alignment of workpieces

Rotary indexer RS-900A

The alternative to turntables: Powerhouse, precision expert and space saver - With the RS series, Nabtesco has high-precision cycloidal transmissions designed specifically for heavy-duty positioning, providing an optimal alternative to rotary tables. These precision gears with hollow shaft have an integrated bevel gear and a stable, durable construction. The hollow shaft makes it easy to perform supply lines and cables. In addition, these precision gears work virtually backlash-free. The RS-900A precision gear is designed for axial loads of up to 9 t and achieves a positioning accuracy of less than 1 arcmin.
