Gearwheels and Power Transmission Equipment for the Rail Industry

Blue Gearboxes

Katsa Oy provides power transmission components and systems, high-accuracy gearwheels and tailor-made gearboxes for specific rail applications.

Gearboxes for industrial applications

Katsa gears and gearboxes are used worldwide for a variety of purposes, including wind turbines, marine engines and propulsion systems, railway applications, mobile mining machines, and army vehicles.

We are able to provide clients with R&D services, from full gearbox design to re-engineering components for refurbishment. Gear calculations, finite element (FE) analysis and gearbox simulations are all performed by our experienced designers.

We have seven Pfauter & Reishauer gear-grinding machines and more than ten Pfauter gear-cutting machines. We are fully independent regarding heat treatment, with four Ipsen furnaces weighing between 1,000 and 5,000kg.

Katsa gearboxes are tailor-made to meet customer requirements in the railway industry.
Our gearwheels feature ground tooth flanks up to 1,600mm deep.
Gear flanks are inspected with CNC-controlled, special gear-measuring machines.
As well as railway applications, our gears are also used in army vehicles and mobile mining machines.
Gearboxes can be adjusted to have an output torque up to 300kNm.
Katsa collects data during the manafacturing process for R&D purposes.
The Katsa PTO gearbox is a modular construction meeting your demands.

Gearwheels for the railway industry

Our gearwheels are capable of grinding to a depth of 1,600mm, and cutting up to 2,500mm. They also feature worms with a size of up to 350mm, and worm wheels up to 2,500mm.

Tailor-made gearboxes

Gearboxes can be tailor-made according to the client’s specifications. They come with a wide range of features, including:

  • Output torque up to 300kNm
  • Speed reduction ratio area from 1,800:1-2:1
  • Speed-up ratio area from 1:2-1:10
  • Maximum axial shaft distance: approximately 800mm
  • Input power: approximately 2MW

All gear types and combinations are available.

About Katsa

Katsa’s skilled, experienced workers use ISO-certified QHSE systems to develop our products. Our intranet comes with high-quality instructions to allow for quick, easy accessibility across the board.

Katsa collects data during the manafacturing process, which allow us to constantly improve our services. For example, air-conditioning is now included at the end of the process to mantain a constant grinding temperature, and thereby achieve the highest possible accuracy.

Gear flanks for all Katsa products are inspected using CNC-controlled special gear-measuring machines (geometrical measurements are also possible).

All products endure a separate final inspection and classification. They also feature an individual serial number, the base of quality control and 100% traceability.
