TwinSpin H Series – Reduction Gears
The TwinSpin® H Series is a range of high-precision cycloidal reduction gears featuring a central through-hole. This hollow-shaft design allows cables, pneumatic lines, drive shafts and other services to be routed directly through the centre of the gearbox, helping simplify machine design and installation.
The reduction mechanism and high-capacity radial-axial output bearing are integrated within a single compact unit. This enables the H Series to transmit high torque while supporting external radial, axial and tilting loads without requiring additional output bearings.
Low lost motion, high torsional rigidity and excellent positioning accuracy make the TwinSpin H Series suitable for demanding motion-control applications where precise, repeatable movement is essential. Its compact construction can also help reduce the size, weight and number of components within the finished machine.
Typical applications include:
- Industrial and collaborative robots
- Robot joints and rotary axes
- Machine tools
- Rotary tables and positioners
- Handling and automation equipment
- Medical and laboratory systems
- Inspection and measurement equipment
