The radial roller bearings with pin for lift truck mast are made up of a radial counter-pressure roll (appropriately shaped) fitted flush to a mild-steel pin.
Any axial load that may develop within the system must be supported separately from other elements.
They are manufactured in shielded version, therefore relubricatable, and watertight version.
