Expansion of the RS series
The Nabtesco RS series stands for high-precision positioning of heavy loads. Compared to conventional rotary tables, this solution has a clear advantage in many applications. Nabtesco has therefore extended the series with a new size: The RS-50A positions loads up to 1,000 kg with high precision and ensures significant performance increases in handling and assembly.
The RS series features an integrated right-angle gearbox and a sturdy, durable construction. It has been designed for high loads, positioning accuracy < 1 arc.min and is clearly superior to conventional camshaft or worm gears in positioning. Thanks to the integrated cycloid gear, high-precision positioning can be carried out.
Advantages:
- reliable, accurate positioning of heavy loads
- Main bearings allow axial loads up to 9t (RS-900A)
- Hollow shaft (for passing through cables etc.)
- Cast iron base for stable floor mounting
- Easily accessible, right-angled mounted motor
Areas of application:
- Robotics
- Machine tools
- Welding positioner
- Turntables
