Upper rollers and Lower rollers also named Top Rollers, Bottom Rollers which support the weight of the shovel and spread weight effectively. 
We offer one piece forged upper and lower rollers,which are instrumental in maintaining a smooth path for the track shoes, allowing them to move with ease and distribute the weight of the machine evenly across the track structure  resulting in low ground pressure and excellent stability.
