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.
The fixed design does not allow axial screw-down.
They are manufactured in shielded version, therefore relubricatable, and watertight version.
