Xubi Engranajes

What Xubi Engranajes does

Xubi Engranajes, S.L. is a Spanish precision gear manufacturer and the core operating subsidiary of the family-owned Xubi Group, founded in 1956 in Azkoitia, Gipuzkoa, Spain. The company designs and manufactures high-precision, custom-engineered gear components — including helical/spur, spiral bevel, double helical, internal/annulus, worm, pinion shafts, girth gears (up to 14,000 mm diameter) and gear racks — serving B2B industrial customers across wind energy, mining, construction, steel, marine, aerospace, railways, telecommunications/satellite communications, machine tools, refineries, and cement.

The technical backbone is HPG-S (Hinterer Profil Geblase - Spiral) gear cutting executed across Klingelnberg, Oerlikon, and Gleason systems, combined with large-scale profile and gear grinding (up to 14,000 mm diameter), coordinate-measuring-machine-based verification, and 100% climatized finishing zones. Tolerances reach DIN 3962 grade 4 on precision components, with grade 5–8 across the broader product portfolio. The group's 32,000 m² of facilities and ~252 employees support a custom, quote-based B2B revenue model with an 80% export mix, executed via direct enterprise sales and dedicated international sales offices. Complementary service revenue comes from gear design engineering, reverse engineering of replacement parts, and on-site technical/maintenance support. Commercial demand generation is event-driven, anchored on a dense calendar of European trade shows (BAUMA, Hannover Messe, Wind Europe, Innotrans, SMM, Europort, EMO, Minexpo).

Within Xubi Group, Xubi Engranajes is the centerpiece of a four-company precision mechanical transmission platform that also includes Renogear (slewing bearings, founded 2008), BSG Zuazo (high-precision ball screws and spiral bevel gears, founded 1980), and Osatu (cylindrical part machining services, founded 1998). The group has recently expanded capacity for large girth gears and entered the aerospace sector as a new vertical, while maintaining the certifications (ISO 9001 and ISO 14001), multi-generation manufacturing know-how, and customer relationships that underpin its incumbency with European industrial OEMs.

Core offering

Xubi Engranajes designs, engineers and manufactures custom high-precision industrial gears (helical/spur, spiral bevel, internal, double helical, girth, pinion shafts, worm gear sets, straight bevels, and racks) up to 14,000 mm in diameter. The company provides complementary engineering, reverse engineering, and on-site maintenance services to industrial OEMs and operators across wind energy, mining, construction, steel, marine, aerospace, railway, telecommunications, machine tool, refinery, and cement sectors.

Product overview

Xubi Engranajes is a precision gear manufacturing company and part of Xubi Group, offering a comprehensive portfolio of high-precision transmission components. The core product portfolio consists of nine distinct gear types: Helical/Spur Gears, Spiral Bevel Gears, Internal/Annulus Gears, Girth Gears, Double Helical Gears, Pinion Shafts, Worm Gear Sets, Spur/Straight Bevels, and Gear Racks. These products are used across gear trains in wind gearboxes, mining, cone crushers, propulsion thrusters, and turbo and compressor applications. Complementing the gear products are three service offerings: Engineering and Gear Design, Technological Support and Maintenance, and New Product Development. The company positions itself as a European leader in precision gears, with manufacturing capabilities spanning from standard modules to very large gears up to 14,000 mm in diameter.

Direct peers

• David Brown Santasalo: Specialist industrial gearbox manufacturer serving mining, steel, marine, power, and cement — the same heavy-industrial verticals Xubi targets. Closely comparable on custom engineered gearing and large-format capability.
• Klingelnberg: German gear technology specialist (now part of the broader drive technology group) and the originator of the HPG-S gear cutting process that Xubi explicitly uses. Direct technical comparable in spiral bevel gear cutting, bevel gear blanks, and gear metrology.
• Gleason Corporation: Rochester, NY-based global leader in gear technology, supplying both gear manufacturing equipment (including Klingelnberg-line HPG-S class systems) and finished high-precision gears. Highly comparable to Xubi on spiral bevel and large-format precision gear capability, though Gleason is materially larger and more diversified.
• Cotta: US-based specialty manufacturer of custom precision gears and gearboxes for aerospace, defense, mining, and industrial markets. Highly comparable in size and in custom-precision positioning, particularly for aerospace gear applications.

Emerging players

• Spinea: Slovak precision gear manufacturer specializing in cycloidal reduction gears and slewing bearings for robotics, machine tools, and aerospace. Comparable on precision custom-gear manufacturing and overlap with Xubi's BSG Zuazo ball-screw / spiral-bevel line.

Broad incumbents

• Flender (a Siemens business): Siemens-owned mechanical drives business producing gearboxes for wind, mining, cement, and marine. Competes with Xubi for wind gearbox components but as part of a far broader Siemens industrial portfolio.
• SEW-Eurodrive: Large German drive-technology group producing gear motors, gear units, and mechatronic drive systems. Competes with Xubi in industrial gear segments but is far larger and more focused on standardized modular products.
• Nidec: Japanese global leader in motors and precision gear components, serving industrial, automotive, and appliance end markets. Adjacent comparable in precision gear manufacturing scale and quality positioning.
• Bonfiglioli: Italian manufacturer of gearmotors, gearboxes, and drive systems serving wind, construction, marine, and industrial markets globally. Competes with Xubi for industrial gearbox content in wind and heavy industrial applications but offers a much broader packaged-product portfolio.
• ZF Friedrichshafen: Global technology group supplying industrial drives, marine and wind drivetrains, and chassis technology. Overlaps with Xubi on wind and marine gearing but operates at vastly greater scale.
