The increase in engine performance and the continuous increase in accessory components have been considered during the design development and choice of materials used for all rigid components.

The control components for accessory devices, with both fixed and automatic tensioning, must meet the growing needs of the manufacturers:

  • Increasingly reduced workspaces
  • High temperatures
  • Continuous stress
  • Increase in the component replacement interval

It follows that both tensioners and pulleys/belts of the system must meet extremely high quality standards.

The fundamental types of rigid components are:

FIXED TENSIONERS: the final tension on the belt is applied through the correct setting of the tensioner and remains constant over time. The belt tension is therefore determined during installation, in which case we recommend using the Dayco DTM Tensiometer to ensure that everything functions correctly.

AUTOMATIC TENSIONERS: they can be spring or hydraulic. They are dynamic tensioners because once properly installed, they will adapt to the operating conditions of the engine and optimize the belt tension according to the stresses received from the engine, in all operating conditions.

IDLER PULLEYS: they are pulleys with or without support that help the belt circuit, effectively contributing to the restraint of misalignment and noise reduction.

Dayco supplies the components necessary to accommodate the range of heavy-duty vehicles.

Dayco is present worldwide as an original equipment supplier for heavy duty vehicles.
