Spot and path-accurate welding thanks to high-precision gears
The use of robots and automated systems in welding leads to higher productivity, improved quality and considerable cost savings. With our gearboxes, you can fully exploit the potential of welding automation. The cycloidal gears and strain wave gears offer maximum precision, dynamics and reliability and guarantee exact positioning of workpieces, components and welding heads. Users benefit from consistently high weld seam quality, minimal reworking and shorter production times.
Precise alignment of workpieces, components and welding heads
Automated welding systems must work quickly and with absolute precision. Our gearboxes provide the necessary "sensitivity" during processing. They enable fast acceleration and deceleration and position with high precision. Welding points - even complicated geometric structures - in the hundredths of a millimeter range can be welded with pinpoint accuracy without having to unclamp and reclamp the workpiece. In addition, the gearboxes have a compact design, can absorb high impact loads and are characterized by low wear and quiet running over the entire period of use.
The advantages at a glance:
- Extreme precision (strain wave gears: absolutely zero backlash, cycloidal gears: hysteresis loss < 0.5 arcmin)
- High torsional and bending rigidity - even at high speeds and high loads
- High dynamics: rapid acceleration and braking
- High shock load capacity (500 % of the rated torque)
- Insensitive to vibrations
- Low wear over the entire service life
- Compact design - ideal for small installation spaces
- Maximum reliability and durability
- High degree of process reliability

Variable 2-axis positioner for welding applications
Our RSX-40K variable 2-axis positioner meets the highest demands in terms of accuracy, dynamics, load capacity and durability. It can accommodate payloads of 4 t and has two axes: one for turning and one for swiveling. The additional swivel axis allows the operator to adjust the positioning to his personal requirements. This ensures ergonomic work during welding.
About the RSX-40K
Hollow shaft gearbox
We offer you a large selection of gearboxes with hollow shafts. The hollow shaft is generously dimensioned and offers sufficient space for cables, hoses and supply lines. Inside the gearbox, they are not only optimally accommodated, but also optimally protected from external influences during welding.
