The Schaeffler brothers jointly founded LuK Lamellen und Kupplungsbau GmbH in Bühl in 1965. The company became the market’s technological leader with its very first innovative product, the diaphragm spring clutch. LuK is one of the world’s biggest clutch manufacturers and a drive train specialist, and has been part of Schaeffler since 1999. Undisputed Competence in the Drive Train
In vehicles with manual transmission, the clutch is the heart of the powertrain. It enables starting and changing gears, as it can separate or dose the power transfer from engine and gearbox. In the non-actuated state, it establishes a frictional connection and thus allows the transfer of the engine torque to the gearbox. If the clutch is actuated, this connection is disconnected. In vehicles with manual transmissions, clutches make a significant contribution to comfort behavior – whether it be through soft starting, fast shifting or smooth running.
In addition to the classic manual transmission, the decoupling of engine and gearbox also takes place in modern vehicles with double clutch transmissions – but in these cases automatically and with the help of two clutches.

A comfortable and efficient power transmission, combined with a long service life, is the basic requirement for the powertrain. Reducing sustainably fuel consumption and the associated emissions without sacrificing comfort, requires an in-depth and detailed knowledge of the overall drive system and its individual components. These include clutch, vibration damping, release systems and gearbox. With its LuK brand products, Schaeffler offers everything that is required for efficient, dynamic and energy-saving power transmission, both for the original equipment and the spare parts market.
| LuK DMF: for the easy change of a dual mass flywheel. If the dual mass flywheel is defective, it is recommended to replace it. The LuK DMF is the repair solution for a fast, professional replacement. This requires either the matching LuK RepSet or LuK RepSet Pro. By the way: whether the DMF is worn can be easily tested with the LuK DMF testing tool in the installed condition.

Intelligent hydraulic components from Schaeffler – for a professional repair
As an important component of modern clutch systems, the release system, the connection between pedal and clutch, has a decisive influence on the driving experience. To ensure that the clutch is easy to operate and that the power flow can be safely metered, all components of the release system must work perfectly together.
Today’s vehicles are usually equipped with a hydraulic clutch actuation. This technology includes slave cylinders, master cylinders, release bearings and hydraulic pressure pipes. In fully hydraulic systems, a concentric slave cylinder (CSC) is used, which combines slave cylinder and release bearing in one component.
Comprehensive Schaeffler expertise – also in the independent aftermarket
Under its LuK brand, Schaeffler has played a decisive role in the development of hydraulic clutch actuation technology. Today, the company also offers all components of the release system as spare parts for the independent market in case of a defect, certainly in the usual OE quality.
As one of the main modules in the powertrain, the gearbox enables the torque of the engine to be transmitted. It provides different ratios so that the engine speed can be flexibly adapted to different driving situations
Thanks to more than 50 years of experience in the areas of clutches, release systems, dampers and gearbox components, Schaeffler with its LuK product brand offers a profound understanding of all four technologies. Schaeffler engineers develop new, innovative solutions on a daily basis, based on their knowledge of cause-and-effect relationships, power transmission and wear – both for original equipment and for the spare parts market.
- Manual transmissions
- Automated manual transmissions (such as double clutch)
- Automatic transmissions
- Continuously variable automatic transmissions (CVT)
| The LuK GearBOX is individually matched to the respective gearbox and contains exactly these wear parts. Due to detailed repair instruction, the LuK GearBOX enables a reliable repair of the gearbox in the independent garages.

Plate-link chain from Schaeffler enables high torque and efficiency
Early on, Schaeffler developed an innovative type of chain that sets standards in the market today. The patented plate-link chain enables a high torque to be transmitted and achieves a better efficiency than conventional push-belts. Thanks to its modular design, this innovation from Schaeffler also covers the entire torque range from small cars to the upper middle class.Thanks to the continuous conversion of engine speed and torque, modern CVT transmissions are highly efficient and impress by a high level of driving comfort, as the engine can always be operated in the optimum range. A further advantage: the elimination of the tractive power interruption during gear changes increases the driving pleasure.However, these continuously variable transmissions are also subject to natural wear, especially since the slide rail and the loop element (belt, chain or strap) in particular are exposed to high loads.
