Mayr

What Mayr does

Mayr power transmission (legal entity: Chr. Mayr GmbH + Co. KG) is a privately held, family-run German manufacturer of mechanical power transmission components, founded in 1897 and headquartered in Mauerstetten in the Allgäu region. The company designs, manufactures, and sells spring-applied electromagnetic safety brakes, torque limiters, and shaft couplings under the ROBA and EAS product families, operating on a fail-safe principle where brakes close via spring force when de-energized. Its portfolio spans elevator and stage brakes (ROBA-stop silenzio, ROBA-duplostop, ROBA-secustop), industrial brakes (ROBA-stop M series, ROBA-topstop, ROBA-linearstop, ROBA-guidestop), torque limiters (EAS-compact, EAS HTL, ROBA-contitorque, ROBA slip hub), and shaft couplings (ROBA DS in servo, steel, aluminum, and heavy-duty variants). The company layers monitoring and supply modules (ROBA brake-checker, ROBA-gateway, ROBA SBCplus) on top of the core hardware, enabling sensorless condition monitoring of brake operating state through current and voltage waveform analysis.

Mayr's customer base spans elevator/escalator OEMs, stage technology builders, industrial machinery manufacturers (machine tools, packaging, printing, extruders), automated guided vehicle producers, wind turbine manufacturers, tunnel boring and mining equipment suppliers, and test stand operators — with named reference customers including VFA-Interlift member companies, Ritter Maschinen, and Power Jacks. The company sells through a quote-based pricing model supported by an online product configurator that outputs CAD files (IGES, STEP, DXF) and price/delivery-time quotes. Go-to-market combines wholly-owned subsidiaries in the USA, France, Great Britain, Italy, Singapore, Japan, Spain, and Switzerland with approximately 40 additional country representatives, alongside centralized manufacturing in Germany, Poland, and China (with an India branch under development).

Revenue mechanics are hardware-sales-driven, with customization as a recurring theme: customer-specific solutions constitute one of five named revenue streams alongside safety brakes, torque limiters, shaft couplings, and supply/monitoring components. Mayr self-describes as the world market leader in safety brakes, torque limiters, and shaft couplings, holds multiple registered trademarks (ROBA, EAS, smartflex, tendo) and a pending patent on elevator-brake damping technology, and maintains functional-safety and industry certifications (EN ISO 13849, ATEX, CSA, UL, FCC, AEO, ISO 8100) that qualify it into safety-critical OEM designs. The company is led by Managing Partner Ferdinand Mayr (M.Sc.) and CFO/Managing Director Christian Illig.
