Quel est le synonyme de galet en mécanique d’undercarriage ?

Expert Answer

In the mechanical sense, the closest English synonym for galet is roller; on tracked machines it can also mean idler or track roller depending on the exact part. For excavator and dozer undercarriages, the correct term depends on the component’s location and function.

A track roller supports the chain and carries machine weight along the bottom of the undercarriage. An idler is usually the front guide wheel that helps steer and tension the track. If the part is a small guide wheel, support wheel, or running surface component, roller is often the safest translation, but it is not always interchangeable with idler.
