Simple and Cost-Effective Architecture

Unlike our higher-end models, Heliks uses a conventional planet carrier (not a cage-type design), enabling a simpler construction and an excellent price-to-performance ratio.

The output shaft is supported by two front-mounted ball bearings (cantilever configuration), which simplifies the design while still providing excellent shaft guidance for applications with moderate performance requirements.

Low-backlash and helical toothing

Heliks delivers 5 arc-minutes of backlash thanks to its highly precise, carburized and quenched helical gearing, ensuring:

quiet operation,
smooth torque transmission,
and a long gear service life.

Especially suitable for:

applications with moderate radial and axial loads,
cost-efficient axes with standard duty cycles,
systems requiring low backlash without the need for extreme rigidity,
projects where competitiveness is a key factor without compromising reliability

Fast, Secure and Hassle-Free Connection

The motor-shaft interface uses a precision-balanced coupling, engineered to minimize bearing loads on the motor and ensure smooth, vibration-free operation.
Installation is quick and intuitive thanks to a single-bolt clamping system on the motor shaft, guaranteeing a firm and dependable assembly
Each gearbox is supplied with a motor-specific adapter flange, ready for immediate integration.

Performance Highlights

Precise positioning
Backlash stability over time
Reduced wear and long service life
Smooth and accurate motion in standard applications
