Alignment & Slewing Gearboxes
Achieve precise, repeatable motion — even with large masses.
When precise alignment, high loads, and maximum repeatability are critical, alignment & slewing gearboxes are the right choice
The alignment & slewing gearboxes are designed for high-precision positioning and slewing tasks where large masses must be moved safely, repeatably and with minimal backlash — even under high torque and demanding operating conditions.
Technical highlights of the alignment & slewing gearboxes
- Torque: up to 100,000+ Nm (application-specific)
- Design: single-stage or multi-stage, depending on required reduction
- Backlash: low-backlash or adjustable down to < 0.02°
- Ratios: defined individually, multi-stage possible
Additional sizes, torque ranges, and gear ratios available on request.
Sizes in detail
The slewing gearbox series comprises 6 sizes with the following nominal output torques:
| Size | Type | Nominal Output Torque |
|---|---|---|
| Smallest | GP-22 | 220 Nm |
| GP-50 | 500 Nm | |
| GP-160 | 1'600 Nm | |
| GP-500 | 5'000 Nm | |
| Largest | GP-3000 | 30'000 Nm |
Important:
Our solutions are typically based on modified standard gearboxes that we adapt to your space, torque or interface requirements — saving time and budget.
If your project requires more, we develop a special gearbox design in close collaboration with you.

Frequently asked questions about AKIM Gearboxes
When do I need an alignment or slewing gearbox?
Whenever you need to move large masses precisely, repeatably and safely - and standard gearboxes are no longer sufficient.
Typical applications:
- Alignment & tracking drives: precise alignment that stays in position
- Antenna & radar systems: positioning with high safety requirements
- Slew drives in heavy machinery: large masses that must move precisely
- Positioning drives: where the highest safety is required
How does the custom design process work?
Each alignment & slewing gearbox is engineered in close collaboration with you. Together we analyze load cases, duty cycles and operating conditions. We size the gearbox stages and bearings specifically for your application and define all interfaces: flanges, shafts, motor mounts; to match your design. The result: a solution that truly fits your application, not one that “almost fits.”
Are spare parts available for old AKIM gearboxes?
Yes! We supply spare parts even for gearboxes from the 1920s. Our documentation is complete.
