Thrust rollers, sometimes also called thrust idlers, are positioned on the uphill and downhill edges of the tire (riding ring), preventing the drum from drifting too far one way.

Sizes ranging from 7-¾” to 48” diameters are available.

Indications That a Thrust Roller may Need Replacement

Thrust roller damage is apparent if the roller has become too small, or the shaft is broken. Similarly, rollers may also exhibit a flat spot, where the drum has been allowed to ride for an extended period of time.
