Mast Roller BearingMast roller bearing used in the forklift upright assembly to carry side and load thrust as the carriage and inner channels travel vertically under load through the lift cycle. Supplied as an aftermarket replacement under part number AC1901-55069. Bearing geometry, race hardness, crown profile, and seal style match original specifications so the mast tracks cleanly through full lift height without binding, channel marking, or premature track wear. Routine inspection during mast service is recommended, since worn rollers accelerate channel wear and contribute to lift drift.
