A central lubrication system for lubricating a telescopic shaft (1, 101, 201) has a lubrication device (10, 110, 210) and an inner profiled tube (2, 102, 202) of the telescopic shaft (1, 101, 201). The lubrication device (10, 110, 210) is insertable into the inner profiled tube. At least one feed duct (11, 111, 211) feeds lubricant to the portions of the telescopic shaft (1, 101, 201) to be lubricated.
