Only the best German manufacturers
Tooley Imports only buy new parts direct from the German manufacturers and worldwide distributors. This gives us access to the most popular and well established German brands in the motor vehicle industry.
Vehicle applications have become increasingly complex and demanding, and LuK continues to live up to its reputation for designing and manufacturing clutches and clutch system components that meet those demands. LuK has earned its place as the leading original-equipment clutch supplier by setting the standard for clutch performance.
LuK clutches and discs undergo rigorous testing at each step in the production process, from component parts through final assembly testing. As vehicle applications become more complex and demanding, LuK’s reputation for producing proven, high-quality products continue to lead the way.
The flywheel is an integral part of your clutch replacement. It can make the difference between a satisfied customer and a comeback. Whether you choose a conventional direct replacement or upgrade to an aluminum performance flywheel, LuK has you covered. All new, never resurfaced, a LuK flywheel is the smart choice for your application.
The clutch disc is the clutch’s central connection element.
In combination with the clutch pressure plate, it both separates and links engine and powertrain. It also reduces the speed fluctuations in the gearbox caused by the combustion motor. LuK offers the best solutions for every application, from clutch discs with simple torsion damper through to variants with multi-stage dampers, from rigid clutch discs for use in the dual mass flywheel right through to the displacement correction clutch disc.
Together with flywheel and friction disc, the clutch pressure plate forms a friction system and is mounted to the flywheel by bolts in the housing. The pressure plate ensures that the engine torque is transferred via the friction disc to the transmission intake shaft. In the 70’s, the diaphragm spring clutch has consistently eliminated bolt springs from the passenger car.
LuK was the first manufacturer in Europe to develop and sell a dual-mass flywheel in large-scale standard production that was able to realize this physical principle. The name says it all: The mass of the conventional flywheel was simply split in two. One part continues to belong to the engine’s mass moment of inertia, while the other part now increases the mass moment of inertia of the transmission. The two decoupled masses are linked by a spring/damping system. One clutch disc, without a torsion damper, between the secondary mass and the transmission handles the engaging and disengaging functions. A favorable side effect is that the transmission is easier to shift because of the low mass to be synchronized, and there is less synchronization wear.

Rolling bearings generally comprise two bearing rings with integral raceways. Rolling elements are arranged between the rings and roll on the raceways. Rolling elements can be balls, cylindrical rollers, needle rollers, tapered rollers or barrel rollers. The rolling elements are generally guided by a cage that keeps them at a uniform distance from each other and prevents them coming into contact with each other. In needle roller bearings and ribless spherical roller bearings, the cage also ensures that the rolling element axis is positioned correctly. Where bearings can be dismantled, the cage holds the rolling elements together and gives easier fitting of the bearings. For particular applications, rolling bearings with a full complement of balls, cylindrical rollers or needle rollers may be used.
The standard material for sheet metal cages is steel, while brass is also used for some applications. Solid cages are made from brass, steel, laminated fabric and other materials. Cages made from thermoplastic materials are also widely used, especially those made from polyamide reinforced by glass fibre.
Rings and rolling elements are predominantly made from through hardened chromium steel, although case hardening steel is also used. Special bearings for extreme operating conditions – load, speed, temperature, corrosion – are made from temperature-resistant and/or corrosion-resistant steels, plastic, ceramics or other materials.
Rolling bearings are available in open versions or with seals on one or both sides. The most common types of seals are gap seals and lip seals.
Plain bearings are available as radial bearings, axial bearings, strips, cups and in many other designs. They run quietly and are particularly suitable where high loads must be supported under relatively slow rotary and swivel motion and at low and high temperatures. Due to their versatile specific characteristics, they are therefore used in almost all areas of industry and especially where the space available for the bearing arrangement is very limited.
