The gearbox manufacturing market is experiencing robust growth, driven by significant government investments in India’s railway sector and the introduction of advanced train systems like Vande Bharat, marking a shift from traditional locomotives. Manufacturers with longstanding partnerships in the industry hold strong positions in this evolving landscape, particularly in the traction systems that transmit power from motors to locomotive axle wheels. Beyond railways, the industrial gearbox market has rebounded post-pandemic, with increased demand in sectors like cement, steel, and power, which rely heavily on robust gearbox solutions for applications such as conveying and rotary motion. In addition, the renewable energy sector, supported by government initiatives toward green energy, is accelerating demand for hydro and wind turbine gearboxes.
While many manufacturers produce gearboxes as mass-market items for smaller power transmissions, typically around five, ten, or twenty horsepower, the demands escalate dramatically when moving into larger, more critical applications like steam turbines, where gearboxes start at the megawatt scale. The complexity increases significantly, especially for gearboxes designed to handle power transmission in the range of 50 megawatts, a feat that requires an entirely different level of precision and engineering expertise. Unlike standard gearbox production, which may see hundreds of units produced monthly, these high-capacity units are a different ball game altogether. As the interface between the driving and driven sides, they must be exceptionally robust, precise, and noise-free, ensuring they meet the high-performance expectations of clients.
In addition, another key consideration for clients is the cost-performance ratio. European companies often supply gearboxes to the Indian market at a premium price, placing project managers in a difficult position from the outset, as they weigh the high costs against performance expectations. Balancing cost efficiency with performance is critical, and the ability to deliver high-quality, competitively priced products becomes a distinct advantage. Furthermore, on-time delivery and transparent dealings are essential in large-scale projects, particularly when each gearbox may be worth several crores. Ensuring a reliable partnership throughout the procurement and delivery process is crucial, as clients depend on consistency, transparency, and professionalism when dealing with high-stakes products such as 50-megawatt transmission gearboxes. “This is where a brand like Kirloskar’s reputation, ethics, and dedication to excellence make a significant impact”, says Prafulla Deoskar, General Manager, Sales and Marketing (Transmission Division), Kirloskar Pneumatic Company Limited.
Precision Meets Tradition
Kirloskar Pneumatic Company has long stood as a cornerstone in the industrial sector of India, with a legacy that is storied and forward-looking. In a world increasingly focused on precision engineering and efficiency, the company has managed to strike a balance between tradition and innovation, making it a name synonymous with excellence in gearbox manufacturing. The journey is as much about industrial innovation as it is about adaptability and staying ahead of the curve in an evolving global market. Today, the company’s diverse range of gearboxes and transmission solutions is an integral part of multiple industries, from oil and gas to power generation, sugar, cement, steel, and mining.
Founded in 1958 as part of the larger Kirloskar Group, Kirloskar Pneumatic Company was initially set up to manufacture air compressors and pneumatic tools. Over time, the company expanded its portfolio, recognizing the growing demand for mechanical power transmission solutions. In particular, its gearboxes have become a vital part of the industrial machinery landscape, embodying the high standards of durability and efficiency that customers have come to expect from the Kirloskar name.
Integrated Excellence
The company ensures that all of its products undergo a 100 percent quality inspection in-house, foregoing batch inspections in favor of a comprehensive process inspection. By maintaining a high level of vertical integration, it controls nearly every aspect of production. Even the forgings for gears and pinions, essential components in the manufacturing process, are produced in-house at its dedicated plant in Nashik. This backward integration allows the company to maintain stringent quality control over the raw materials used, ensuring that the steel, once forged, meets the rigorous demands of duty conditions. In contrast to many competitors who source forgings from third-party suppliers, the company takes pride in handling this crucial step internally. In addition, heat treatment, a critical phase in gearbox production, is also performed entirely in-house, ensuring that every gear, pinion, and shaft is treated to the company’s exacting standards. Kirloskar Pneumatic Company even manufactures its housings, with a dedicated foundry for gearbox cases.
Beyond this deep integration, the company operates under an Integrated Management System (IMS), holding certifications in ISO 9001, ISO 14001, and ISO 45001, all of which were recently recertified by TÜV. The level of supervision is essential, particularly in high-sensitivity areas such as renewable energy, where reliability is paramount. The company’s clientele includes major industry players who operate under stringent procurement standards. In addition to meeting these external requirements, the company enforces its own rigorous internal quality controls. Every gearbox is thoroughly tested and certified by the company’s quality assurance team before being offered for third-party inspections or witness testing by its clients. This relentless focus on quality ensures that the company remains a trusted supplier in highly demanding sectors.
Customization and Refurbishment
Kirloskar Pneumatic Company is renowned for its expertise in delivering highly customized products, with 90 to 95 percent of its output tailored to specific client needs. This reputation is built on the company’s strong engineering capabilities and its ability to provide comprehensive technical support. One key area of service is the refurbishment of import substitute gearboxes, often sourced from countries like Germany, China, or Ukraine, where original equipment history is unavailable. Its process involves conducting joint inspections with clients, dismantling gearboxes, and providing detailed reports on which components can be salvaged, what needs replacement, and the cost and time required for refurbishment. The refurbished gearboxes are supplied with full testing, covering vibrations, noise, temperature, oil leakage, and RPM performance, ensuring they meet stringent quality standards.
In addition, Kirloskar Pneumatic Company excels in custom design for new applications. Its application engineering cell first studies the client’s requirements and the duty conditions for the gearbox, analyzing existing equipment and available space. After a thorough evaluation, the company’s design team develops tailored solutions, providing a preliminary offer before proceeding with technical clearances and final production. “Recently, we supplied one-megawatt gearboxes for a sugar mill and also a 600-kilowatt gearbox for a sugar mill in Uttar Pradesh, and both were completed ahead of schedule”, says Deoskar.
