Higher engine performance and the continuous increase in the number of auxiliary components have led to a significant development in the design and choice of materials for all rigid components.
Rigid components must conform to manufacturers’ requirements, including:
- Increasingly confined working spaces
- High injection pressures
- High temperatures
- High stress
- Extended component replacement intervals
As a result, both tensioners and pulleys must meet extremely high quality standards.
The main types of rigid components are:
- Automatic tensioners: these are “dynamic” tensioners designed to adapt to and optimize belt tension in response to engine stress, in any operating condition.
- Idlers: these are a type of pulley (with or without bracket) which ensure correct guiding of the belt during operation. They are extremely important as they support part of the system stress.
