摘要

The hydraulic unit (10) has a hydraulic block (12) and a drive motor (14) for driving a pump element (36) that is externally arranged on the hydraulic block. A motor shaft (20) is mounted on the hydraulic block by a motor shaft bearing (24). The motor shaft bearing is fixed to an element made of synthetic rubber on the hydraulic block. The element made of synthetic rubber is set radially outside on the motor shaft bearing. The element made of synthetic rubber comprises nitrile rubber. The element made of synthetic rubber is used in a groove formed at hydraulic block.
