Heavy-Duty

WHEN SIZE AND PERFORMANCE ARE CRUCIAL

HEAVY-DUTY GEARS FOR LARGE AND HEAVY APPLICATIONS


As the name suggests, our Heavy-Duty products are large gears for demanding tasks. We turn, tooth, harden and surface treat gears up to 5 m in diameter.

These gears are primarily used in the wind turbine industry, but mining, shipbuilding and cement production also benefit from our expertise in this special area. They are used in MAN marine engines and Vestas and Siemens wind turbines.

Thanks to both conventional and state-of-the-art CNC machinery, we can supply large, top quality cylindrical gears. With our own hardening plant, we are also able to offer some of the best quality and delivery times in Europe.

WHEN QUALITY IS CRUCIAL

We believe that the best way to ensure quality, price and delivery reliability is through a well-proven quality structure, process control, continuous training of employees and optimization of both production and measuring equipment.

DURABILITY

Gears that withstand the most demanding situations.

PRECISION

Gears that meet the customer’s specific needs exactly.

QUALITY

Gears with documented quality in each process step.
