The Belt Tensioner Bushing allows smooth pivoting and rotational movement of the tensioner arm while maintaining proper alignment of the drive belt. Guiding controlled motion ensures consistent belt tension during engine operation and load changes. It helps reduce friction between moving components, enabling steady belt tracking across pulleys.Attributes:• Minimizes unwanted noise caused by contact and misalignment.• Helps maintain consistent spacing between connected components.• Reduces impact force during sudden load changes.Applications: The Belt Tensioner Bushing is located inside the belt tensioner assembly, supporting controlled arm movement and maintaining proper belt tension for smooth power transmission and stable drive system operation.
