LuK 510022810 CONCENTRIC SLAVE CYLINDERCSC – the slave cylinder and release bearing in a single component In a modern clutch system it is now more common for pedal force to be transferred by hydraulics rather than a cable. The clutch is actuated by a concentric slave cylinder (CSC), which performs the combined functions of slave cylinder and release bearing. In systems using a CSC, there is no need for release fork or release shaft components. The CSC is positioned directly on the transmission input shaft in the transmission housing. This reduces the number of moving parts in the release system, minimising wear and error influences. Benefits: Weight optimised Heat resistant Long service life Compact system Requires little space, delivers maximum performance Self-adjusting
