Planetary gearboxes for axes that have to reach the exact same position a million times over. Backlash below one arcminute — across the full service life.
Each range is built around a different type of load. Gear quality is identical across all three — what changes is sealing, bearing arrangement and material.
The standard for continuous duty
Single and two-stage, spur-toothed. Rated for 20,000 operating hours in three-shift use with no relubrication.
When repeatability is the spec
Helical teeth, ground tooth flanks, preloaded output bearings. For axes that have to return to 0.01 mm, every cycle.
For the cleanroom and the washdown line
1.4404 stainless housing, crevice-free contour, NSF H1 food-grade lubricant. Cleanable at 80 °C and 100 bar.
Four figures are enough for a defensible shortlist. The maths runs in your browser — the same formulas our application engineers use.
beyond 100,000 h — grease and shaft seal become the limit, not the gear train

Gear cutting, heat treatment and grinding sit under one roof. That is why we can commit to tolerances that would otherwise be spread across three suppliers.
Your load spectrum goes straight into the FEM calculation. The result is service life for your actual application — not a catalogue figure.
Turning and hobbing from 16MnCr5 case-hardening steel. Every batch stays traceable via its heat number.
Vacuum carburising, gas quenching. Case depth 0.6 mm, surface hardness 60 HRC.
Hard finishing after hardening. This is where DIN quality 5 is created — and with it, the running noise.
Assembled in a temperature-controlled room, then 100 % tested: backlash, torque curve, noise, leak tightness. The report ships with the gearbox.
Four out of five gearboxes leave the plant in a customer-specific version — adapted flanges, shafts, lubrication or sealing.
Articulated axes and linear units running high cycle rates with minimal return error.
Format adjustment and indexing drives in continuous, often three-shift, operation.
Imaging systems and patient positioning — quiet running, maintenance-free.
Swivel and rotary axes with high tilting rigidity under cutting forces.
Cleanroom wafer handling, built low-particle and vacuum-compatible.
Test rigs and actuators with complete batch traceability.
Every gearbox leaves the plant with a serial number under which material batch, hardening record and test bench data stay retrievable for ten years.
From the heat number of the steel to the signature of the fitter.
No sampling. Every single gearbox runs on the test bench.
Gear measurement is climate-controlled — otherwise you measure room temperature too.
A southern German builder of cartoning machines arrived with what looked like a motor problem: format adjustment wasn't settling cleanly on target, and at higher cycle rates the axis kept oscillating.
Measurement on our test bench showed it wasn't the drive but the backlash in the existing gearbox that was limiting the control loop. With the HGX range and an adapted output shaft, the controller could be tuned far more aggressively.
“We spent three months blaming the controller. In the end it was two arcminutes of backlash.”
Torque curve, cycle rate and required accuracy are enough for a first sizing. You get a proposal with service life calculation within two working days.
