What RSB does

RSB Transmissions (I) Ltd. (RSB Group) is an India-headquartered, Bain Capital-backed Tier-1 automotive components manufacturer founded in 1973 by R. K. Behera and S. K. Behera in Jamshedpur. The company designs, develops and manufactures drivetrain aggregates and systems - propeller shafts (largest India M&HCV market share), rear and front axles, gearboxes, transmission gears/shafts/hubs, fifth wheel couplings, bevel gear boxes and suspension systems - as well as construction and mining equipment structural parts (main frames, booms, arms, buckets) and agricultural and industrial gear components. Primary customers are OEMs including Tata Motors, Ashok Leyland, Mahindra, Daimler, Volvo, JCB, Caterpillar, John Deere, Tata Hitachi, TAFE and Isuzu. The company operates 15+ plants across India plus wholly-owned facilities in Homer, Michigan (USA) and Silao, Guanajuato (Mexico), with a captive R&D arm, I-Design Engineering Solutions Ltd., based in Pune.

The business model is B2B hardware sales - approximately 75% of revenue from OEM automotive components and 25% from construction/mining equipment, supplemented by a dedicated aftermarket channel for replacement parts. Pricing is quote-based, negotiated under multi-year OEM supply contracts; aftermarket pricing is handled through dedicated sales contacts. RSB monetizes its technology stack partly through long-standing technical collaborations - Eugen Klein GmbH (Germany) for propeller shafts since 2004, Reyco Granning (USA) for suspensions since 2021 and EVR Motors (Israel) for EV motors since 2023. Recent moves include a 2026 multi-stage acquisition of Setco Auto Systems (clutch systems, up to ₹580 crore) and a stated 2030 revenue target of ₹10,000 crore versus ~₹3,000 crore today. Quality is anchored by the 2013 Deming Prize, multiple TPM Excellence Awards, IATF 16949:2016 and ISO 9001:2015 certifications across all plants.
