GWB

What GWB does

GWB, legally Off-Highway Germany GmbH, is a German manufacturer of heavy-duty industrial cardan (drive) shafts headquartered in Essen, operating since 1946 as part of the Allison Off-Highway Drive & Motion Systems division within Allison Transmission. The company designs and produces two core product families — closed bearing eye shafts (Series 587, 687/688) for mobile and general mechanical engineering use, and split bearing eye shafts (Series 390, 392, 393, 492, 498, 598) for heavy and super-heavy-duty applications — covering a torque range from 2,400 Nm to 16,300,000 Nm, complemented by customized solutions such as the Tripod high-speed rail shaft, quick-release couplings (Series 230-330), companion flanges, and journal cross assemblies.

The technology stack is anchored in proprietary IP (patented self-centering journal cross design, patented lightweight heavy-duty spline sets, carbon fiber center sections), advanced manufacturing (submerged-arc welding, specialized balancing up to G16 at 3,600 rpm for shafts over 200 kg, surface treatments including chrome, nickel, gas-nitration, phosphate, and plastic coating), and application-specific engineering software used by in-house engineers to size shafts and evaluate whole-driveline system dynamics including roll geometry, motor/gearbox shaft stiffness, and bearing stiffness.

GWB serves OEMs and aftermarket customers in five verticals — steel, construction, railway, marine, and paper — through a direct enterprise field-sales model with engineering-led custom solutions and feasibility-study support. Revenue streams comprise (i) industrial drive shaft hardware sales, (ii) aftermarket genuine spare parts (journal cross assemblies, companion flanges, quick-release couplings, replacement components), and (iii) service and repair including balancing, X-ray/ultrasonic inspection, refurbishment of flange plates up to 1,500 mm diameter, and on-site maintenance. Pricing is quote-based and undisclosed, consistent with custom-engineered B2B industrial sales. The company holds ISO 9001, ISO 14001, ISO 50001, DIN EN 15285-2 CL1 Werk 2, Deutsche Bahn Q1 (through July 2025), and Spicer/Dana Q1 certifications, and its marine products are approved by all major international classification authorities.

Core offering

GWB designs, manufactures, and services heavy-duty industrial cardan (drive) shafts covering a torque range from 2,400 Nm to 16,300,000 Nm across two main design families — closed bearing eye (mobile/general mechanical engineering) and split bearing eye (heavy and super-heavy-duty). The portfolio is delivered to OEMs and aftermarket customers in steel, construction, railway, marine, and paper industries, alongside genuine spare parts (journal cross assemblies, companion flanges, quick release couplings) and full service/repair including balancing, X-ray/ultrasonic inspection, and on-site refurbishment.

Product overview

GWB offers a comprehensive portfolio of heavy-duty industrial cardan shafts for mobile and industrial applications. The product range is divided into two main types: closed bearing eye shafts (Series 587, 687/688) for general mechanical engineering and mobile applications, and split bearing eye shafts (Series 390, 392, 393, 492, 498, 598) designed for heavy and super-heavy-duty applications. The portfolio also includes customized solutions such as the Tripod shaft for high-speed rail, quick release couplings (Series 230-330), companion flanges with Hirth or Klingelnberg serration connections, and journal cross assemblies as spare parts. These products cover a torque range from 2,400 Nm to 16,300,000 Nm, serving the steel, construction, railway, marine, and paper industries. GWB provides full service and repair capabilities including balancing, disassembly, inspection, and on-site maintenance.

• Flender (Siemens): Manufacturer of mechanical drives (gearboxes, couplings, generators) for industrial and marine applications. Comparable to GWB as a heavy-duty power transmission supplier serving steel, marine and similar heavy industries.
• GKN Automotive: Major global manufacturer of driveline systems, including CV and propeller shafts, serving automotive and industrial customers. Comparable to GWB in cardan shaft technology but with a broader automotive-centric product portfolio.
• American Axle & Manufacturing: Tier 1 driveline and powertrain supplier with global manufacturing footprint, including propshafts and forged driveline components. Comparable to GWB in driveline component manufacturing and OEM-focused business model.
• Bonfiglioli: Italian manufacturer of gearmotors, drive systems and inverters serving industrial, marine and renewable applications. Comparable to GWB in heavy industrial power transmission and project-driven OEM sales.
• Getriebebau Nord: German manufacturer of drive technology (gear units, motors, electronic drives) for industrial applications. Comparable to GWB as a German industrial drive specialist serving similar heavy-industry and OEM customers.
• Rexnord: Manufacturer of power transmission and motion control products including bearings, gears, chains and couplings. Comparable to GWB in industrial power transmission components serving heavy process industries.

Direct peers
