- Self lubricated bushes instead of bearings
- Shafts in stainless steel, this is also useful for strength and avoid stretching
- All the shafts are independently assembled and easy replacement individually.
- Gears are connected individually as well.
- ITF standard friction independent for each rollers and easy to define the individual force load
- Friction adjustable by tool
- Each friction /roller group is independently assembled, with the easy plug/unplug concept in order to reassembly in the correct position each group
