DAYCO brand Belt Tensioner, v-ribbed belt rollers are mechanisms involved in the drive system of motor elements, located in a mounted state. The parts create sufficient tension on the rubber-technical components of the engine and participate in the organization of the stability of the position of the moving components. The operation of the power steering pump (if any), the generator and the water pump, the compressor of the air conditioner depends on their quality. Roller design and tensioner specifications vary by vehicle model and manufacturer.

The functionality of the v-ribbed belt tensioner

In every modern car, the power unit has a belt drive. Through this product, torque is transmitted from the engine crankshaft to the camshaft of the gas distribution system and other auxiliary devices. The main condition for the effective operation of the drive belt is to adjust the required tension so that, due to the frictional force, it drives the pulleys of the system, and does not slide over their surface. Therefore, the design provides for a drive belt tensioner roller, which creates the tension necessary for the correct operation of the mechanism.
