Redex
Linear and Rotary Axis Drives
Redex offers the most comprehensive range of machine-tool axis drives. An integrated output pinion is at the heart of the range – flange-mounted, side-mounted or in a universal housing – with zero-backlash preload options.
- 150 m/minmax. linear speed
- 158,000 Nacceleration feed force
- 90,000 kgmax. axis weight
- 1 – 3 arcminbacklash
The range
The Axis Drive Range
SRP Planetary Servo Reducer
Versatile planetary reducer with ISO 9409-1 output flange; can carry a pinion, pulley or coupling.
- 7 sizes, ratios 5 – 91:1
- 200 – 18,600 Nm
- Up to 6,000 rpm input
KRP+ Kit Reducer
Flange-mounted reducer with integral pinion – single, DualDRIVE or TwinDRIVE.
- 6 sizes
- 105,000 N nominal feed force
KRPX Side-Mounted Reducer
Housing acts as a rigid extension of the machine frame; up to 60% less radial bending.
- 5 sizes
- TwinDRIVE preload
DRP+ Integrated Preloaded Drive
Two reducers in one rigid housing, for DualDRIVE or TwinDRIVE zero backlash.
- 5 sizes
- Zero backlash by design
SRP can also carry a PDP preloaded split pinion – two ground pinions with a patented preload – a competitive alternative to ball screws.
How it works
Zero Backlash on a Rack
Two ways to take the play out.
DualDRIVE – Mechanical Preload
Two reducers drive the same rack and are wound against each other, torsionally preloading the pinions. The play disappears and only one motor is needed, which keeps the control simple.
TwinDRIVE – Electrical Preload
Each reducer has its own motor. One drives the axis while the other applies an opposing torque, cancelling the backlash electronically.
Why Redex axis drives
Stiff, Fast, Accurate
Integrated Pinion
Pinion machined into the output for maximum stiffness on the rack.
Big Bearings
Oversized preloaded output bearings carry high radial and tilting loads.
Dynamic
Acceleration up to 25 m/s².
Flexible
In-line or right-angle motor mounting on every size.
