Thrust rollers are hydraulic 3dimension movable rolls. Thrust rollers
limit the lateral movement of the rotating debarking drum and help
maintain equipment balance. They provide load compensation and are used
to accommodate uneven loads. There are several types of thrust rollers. They can be single and double acting, combination roller and cross rollers.
Inspection of the load bearing surface or the thrust rollers should be done at regular intervals to avoid slow and faulty operations. Thrust rollers can be refurbished and problems like timing marks taper wear and irregular face profiles can be eliminated.
