Belt drives have the task of transmitting and driving the rotary motion of the crankshaft to the engine control system or to the auxiliary units. Belt drive components are therefore required to deliver maximum performance in every vehicle. The central component of the belt drive is the pulley. It transmits the torque generated by the engine to the belt. febi offers a comprehensive range of pulleys in OE matching quality. The two most common designs are vibration-damping pulleys and decoupled pulleys. It is important that the internal structure of the pulley is designed in accordance with the vibrations generated by the motor - this is the only way to compensate these and prevent the transmission of vibrations to the belt drive. febi only supplies pulleys with the same technology of the vehicle manufacturer and the correct internal structure. Our quality management tests the pulleys offered for various requirements and loads, e.g. fitting accuracy, dimensional accuracy, material quality, and tensile strength. In everyday workshop life, it is not uncommon for a worn part to have to be replaced as well as any fixings. However, these additional parts - usually bolts or nuts - are often not included with the individually available replacement part. For certain vehicle types, febi offers pulleys with the necessary fastening material for professional replacement. This is intended for repairs at fair value without delay.
