The clamping bush has a longitudinal slit (2) and at least one lubricating groove (15) with embedded lip seal rings at the inner surface (13) near the end sides (3,4) in the inner edge grooves (16,17). It has at least one lateral drilling (12) linked to a distribution groove (11) worked into the outer surface (14) on the peripheral side. Recesses (5-8) are near the edge grooves, extending from the longitudinal slit (2) in facing pairs, over the whole thickness (D) of the wall (10) in the peripheral direction. Oversized and elastic seals fit into the recess chambers, across the longitudinal slit (2). The seals are of a polymer, a polyamide or similar plastics material.
