Invest in quality CV Tensioners

Dayco, a leading engine products and drive systems supplier for the automotive, industrial and aftermarket industries, has considerable experience and significant original equipment (OE) pedigree in the design and manufacture of commercial vehicle (CV) auxiliary belt tensioners.

Although there are several tensioner design types, each one is designed for a specific application, it’s main body/spring case design, arm offset and length, as well as the pulley size, are all designed to ensure maximum performance of the drive belt system. The tensioner is often an overlooked component, however, it is key to ensure the reliable operation of the vehicle.

The most common tensioner is the low pulley offset design, which Dayco introduced in conjunction with Cummins for its hugely popular B series engine in 1984. In addition to the pulley assembly, this design consists of five main elements: the spring case and spring assembly, the pivot bush, the spring bush, the arm and the arm bush.

Depending on the requirements of a given application, Dayco offers both flat and round wire solutions for the spring material used in the spring assembly. However, as a general rule, a flat wire spring provides the tensioner with the most stable performance across a wider range of movement and therefore is the most favoured by the OE.
