What Tandler does

TANDLER Zahnrad- und Getriebefabrik GmbH & Co. KG is a Bremen, Germany-based precision mechanical-engineering manufacturer founded in 1949 and controlled by the Tandler Stiftung (foundation). The company designs and manufactures custom and standard gearboxes, servo gearboxes (marketed under the ServoFoxx® brand), speed overlay transmissions, and precision toothed components such as bevel gears, spur gears, and spline connections. Its core technical differentiator is 100% Fertigungstiefe — fully in-house production from raw material through heat treatment (operated via wholly-owned subsidiary Härterei TANDLER), gear cutting on Klingelnberg cyclopalloid machines, profile grinding on Reishauer/Refom/Niles equipment, and assembly at a single Bremen facility. Quality control occurs after every manufacturing step, with traceability, gear measurement centers, and materials testing.

The company serves industrial machine builders as its primary segment, with secondary verticals including the food industry (stainless-steel variants), ATEX-certified explosive-environment equipment, and motorsport (including Formula Student and classic-car restoration). The go-to-market is engineering-driven B2B direct sales: customers consult directly with engineers to specify custom small-series or one-off gearboxes, supported by worldwide representation in 25 countries across all six continents. Revenue streams include one-time product sales (custom and standard gearboxes), replacement parts and overhaul services, and contract manufacturing (Lohnfertigung). Pricing is quote-based per specification, with no public price list. The company holds ISO 9001 certification and operates with over 200 specialists. Recent corporate activity is limited to leadership renewal — Walter Haug was appointed Managing Director in May 2025 — and ongoing ServoFoxx® product-line extension into robotics and automation applications.

Core offering

TANDLER designs and manufactures precision gearboxes and gear components at its Bremen facility with 100% in-house manufacturing depth. The portfolio includes bevel gearboxes, servo gearboxes (ServoFoxx® line), speed overlay transmissions, custom special gearboxes, and individual gearing components (bevel, spur, worm, splines, racks). Customers across 25 countries specify custom and small-series solutions in direct consultation with TANDLER engineers, supported by an integrated in-house heat treatment subsidiary (Härterei Tandler).

Product overview

TANDLER is a precision gearbox and gear manufacturer based in Bremen, Germany, established in 1949. The company offers a comprehensive portfolio of mechanical transmission products organized around three core categories: (1) Standard Getriebe — bevel gearboxes, servo gearboxes under the ServoFoxx® brand, and speed overlay transmissions; (2) Sondergetriebe — custom-designed gearboxes and variations of standard products for specialized applications; and (3) Verzahnung — precision toothed components including bevel gears, spur gears, and spline connections. The ServoFoxx® servo gearbox line includes planetary gearboxes (PL2), servo bevel gearboxes (FS2), planetary-bevel combinations (PSK2), bevel-planetary gearboxes (SKP2), and hypoid gearboxes in various configurations with flanges, hollow shafts, and robot flanges. TANDLER maintains 100% manufacturing depth with in-house heat treatment, gear cutting, grinding, and quality control, supplemented by engineering services and racing technology solutions.
