The combined bearings for lift truck mast are made up of two counter-pressure rolls connected to each other by a mild-steel pin.
The rolls (appropriately shaped) have the task of supporting radial and axial loads separately.
This series allows adjusting the axial unit by means of an adjusting screw.
They are manufactured in shielded version, therefore relubricatable, and watertight version.
