Dryer Idler Pulley Assembly
The idler pulley maintains tension on the drive belt; when its internal bearing or bushing fails due to heat-induced lubricant breakdown, it produces a high-pitched screeching noise. If left unaddressed, the pulley can seize completely, leading to belt breakage.

Dryer Drive Belt
A screeching idler pulley often creates excessive friction and heat on the drive belt. Replacing the belt is necessary if the pulley has caused flat spots or glazing on the belt surface, which would otherwise lead to slipping or snapping.

Drum Support Roller
Drum rollers use similar bearing technology to the idler pulley and operate under the same thermal conditions. If one bearing in the drive system has reached its end-of-life cycle, the rollers are statistically likely to fail shortly thereafter.
