💡 Why do serpentine belt tensioners fail on cars?
Ideally they handle rotational stress until the internal bearings wear out from friction.
- It applies steady pressure to the rubber belt preventing slip under load conditions
- High grade bearings reduce heat buildup ensuring smoother rotation throughout drives
- Sealed units lock out dirt keeping internal lubrication fresh for longevity
