Cleaner Rollers with spiral on cage
The steel cleaner rollers are composed of two stout bearing heads, joined together using three shafts at 120°, welded on which are two steel spirals with a right-hand and a left-hand screw.
They are used in conveyors of sticky materials as their form also allows the material to drop through the roller."
