Gears

Precision spur, bevel and worm gears for industrial power transmissions.

Overview

Engineering and manufacturing of gears to technical drawings.

Our gear program covers spur, bevel, worm and special gears produced to the customer's technical documentation or developed in-house through our engineering preparation. We work in small and medium batches with full geometry and material verification at every stage of machining — from basic gearing to special industrial assemblies.

Production program

What we manufacture.

A full gearing assortment — from standard gears to bespoke industrial components built to technical drawings.

01 / 11

Spur gears

Spur gears with straight and helical teeth, diameter up to Ø 1500 mm. A core component of industrial power transmission.

02 / 11

Bevel gears

Bevel gears with straight teeth, manufactured to the customer's technical drawings and specification.

03 / 11

Internal gearing

Internal gearing up to Ø 800 mm — for gear transmissions and special mechanical assemblies.

04 / 11

Worm wheels

Worm wheels with single or multiple starts, to dimension and to specific system parameters.

05 / 11

Worm shafts

Worm shafts with single or multiple starts, matched to the corresponding worm wheels.

06 / 11

Gear racks

Gear racks of module M10, length up to L-3000 mm, for linear transmissions and special applications.

07 / 11

Gear couplings

Gear couplings for torque transmission with compensation of minor shaft misalignment.

08 / 11

Sprockets

Industrial sprockets, diameter up to Ø 1500 mm, for heavy and medium-duty regimes.

09 / 11

Toothed shafts

Toothed shafts up to L-3000 mm in length, manufactured to the customer's technical documentation.

10 / 11

Rollers for paper industry

Toothed rollers for paper-industry applications, per specification and technical drawing.

11 / 11

Special gearing

Custom gearing manufactured to the customer's technical drawings and specific requirements.

Production approach

Industrial precision, made to drawing.

Every gear is built from concrete technical documentation — no templates, with inspection at every stage.

01 — To drawing

Manufactured to technical documentation

Every product starts from the customer's technical documentation or from engineering preparation done in our workshop.

02 — Precision

Technical accuracy and inspection

Accuracy classes per DIN 3962 (grade 7 or tighter), with geometry and material verification at each machining stage.

03 — Batches

Small and medium-batch production

We work in batches sized to industrial needs — from single pieces to repeat series on demand.

04 — Applications

Wide industrial applications

Power transmissions, paper industry, stone-processing equipment, mechanical engineering and bespoke OEM assemblies.
