Advanced heat treatments for racing gears

Racing gears operate under high contact loads, elevated rotational speeds and frequent torque reversals, making surface durability and resistance to fatigue critical. CIMA performs carburizing, vacuum carburizing and nitriding in-house, with the treatment selected according to the gear material, geometry and required performance characteristics. Control of case depth, hardness and metallurgical structure helps address operating conditions associated with tooth flank wear, pitting and repeated cyclic loading. Integrating heat treatment into the manufacturing process allows CIMA to manage these parameters alongside gear geometry and machining requirements.

Transmission components manufactured for racing

In racing transmissions, gear geometry, material selection and surface condition directly influence power transmission, shifting behaviour and component durability. CIMA  produces timing and auxiliary gears, gearbox gears and shaft, spur and helical gears, splined components and other precision drivetrain parts, manufactured around the requirements of the customer and often improved thanks to its 80 years of experience. 

Racing projects often involve low volumes, specialised geometries and application-specific materials and heat treatments and finishing, rather than standardised components. CIMA’s integrated manufacturing capabilities support these development and production programmes, from prototype components to small series.
 

Specific racing applications

CIMA supports a wide range of racing disciplines, each presenting unique transmission challenges related to performance, packaging, durability and operating conditions:

  • Formula racing places extreme demands on transmission packaging, weight and rotational speed. Compact gearsets and transmission components must deliver precise engagement and reliable operation while fitting within highly constrained architectures. CIMA manufactures precision gears, shafts and splined components according to the specific design and manufacturing requirements of each transmission.
  • Formula E transmissions and reduction systems combine high rotational speeds, high power density and strict requirements on efficiency, weight and packaging. The continuous development of electric powertrains also requires rapid adaptation and short development cycles. CIMA manufactures precision gears, shafts and splined components for high-performance electric racing applications, supporting both development programmes and small-series production.
  • GT and endurance racing combine high power levels with prolonged operating cycles. Transmission components must withstand repeated torque loads while maintaining gear geometry, surface integrity and dimensional stability throughout their service life. CIMA supports these applications with precision-manufactured gears and drivetrain components, from development parts to small series.
  • Rally transmissions are subjected to rapid and highly variable load conditions, with frequent changes in torque and operating speed. Gearsets and shafts must therefore combine strength, accuracy and resistance to repeated loading. CIMA manufactures transmission components to customer drawings, with material and heat-treatment specifications defined according to the application.
  • Motorcycle racing transmissions combine high rotational speeds, frequent gear changes and extremely limited packaging space. These constraints place particular emphasis on component dimensions, gear geometry, weight and surface characteristics. CIMA manufactures precision gears, shafts and splined components for specialised transmission applications.
  • Powerboat racing transmissions operate under high power density and demanding mechanical loads, requiring drivetrain components designed around the specific transmission architecture. CIMA manufactures precision gears, shafts and other transmission components for specialised applications, with component geometry, materials and heat-treatment requirements defined by the customer.

Rapid delivery and development support

Motorsport programmes often require short lead times, particularly during development, testing and racing seasons. CIMA is structured to support these requirements, combining flexible manufacturing capabilities with short response times for prototypes, development parts and small-series production. This allows customers to reduce procurement lead times and react quickly to design changes, testing requirements and racing programmes.
