The main characteristic of counter-pressure rolls is that they have high-thickness outer races, rotating in direct touch with the grooves.
They can support high loads, impacts and angular misalignments, thanks to a special geometry of the outer surface generator.
The axial guide (non-dismantable) gives this counter-pressure roll the ability to stand axial thrusts.
The entirely-filled design determines very high load capacity.
The versions with labyrinth plate protection or watertight are also available.
