Katsa

What Katsa does

Katsa Oy is a Finnish industrial manufacturer founded in 1955 and headquartered in Tampere, specializing in custom-designed special gearboxes, precision gear components, and gearbox refurbishment services for heavy-industry B2B customers. The company operates three Finnish facilities — headquarters in Tampere covering sales and gearwheel manufacturing, a Tampere site for design and gearbox assembly, and a manufacturing plant in Ikaalinen for gear blanks and gearbox housing machining. Its core technology is mechanical power transmission, with a vertically integrated in-house production chain spanning gear cutting up to Ø2400mm, case-hardening and heat treatment (up to Ø1500mm / 5 tonnes), DIN 3 class gear grinding (Gleason-Pfauter P1600G), G2.5 high-speed balancing and 5-axis machining, supported by ISO 9001 (since 1993), ISO 14001, ISO 45001, and Six Sigma (since 2012).

The company serves six verticals — marine & offshore, steel & metals, mining & construction, pulp & paper, energy & wind, and vehicles & rail (the last flagged as primary) — supplying components such as main propulsion gearboxes, dredging gearboxes, crusher clutch drives, conveyor drives, paper-machine servo gearboxes, wind turbine gearbox components, and PTO clutches for commercial and defense vehicles. Anchor customers include Metso Outotec (Lokotrack mobile crushing plants since the 1980s), Outokumpu (steel grinding lines at Tornio), Protolab (PMPV6x6 armored vehicles), and Dutch driveline specialist ADS van STIGT, which distributes Katsa products across Benelux, France, Poland and Italy. Since 2024 the company has operated as a wholly-owned subsidiary of US-based Twin Disc, Inc. under the 'Katsa by TwinDisc' brand, using Twin Disc's global distribution network.

Katsa sells via direct enterprise field sales through regional managers covering Nordics, DACH, Benelux/France/Poland and EMEA marine, plus channel partners, generating revenue primarily from custom gearbox and component hardware sales and professional refurbishment/services revenue. Pricing is project-specific, quote-based and structured around multi-year contracts; no public price list is published. No financial figures are publicly disclosed.
