Main Features
Introducing the All New, High Performance, Low Profile
Infinite Positioning Indexer from Nabtesco!
An integrated main bearing allows the following thrust
load capasities with only the gearbox
RS-320A: 5000kg (max), RS-900A: 9000kg (max)
The RS Series incorporate Nabtesco's Near-Zero
Backlash Gearbox with an added right angle feature
to provide numerous benefits over traditional cam
& worm gear turntable designs. The indexer design
provides a long-term trouble free, no maintenance
positioning solution.
The Indexer utilizes a cast iron base for sturdy floor
mounting and a right angle motor mounting which
provides easy access and a low profile.
