BEARING - MAST ROLLER (Doosan DWMB314046)

DWMB314046: A worn mast roller bearing can cause uneven roller wear and increased friction in the mast assembly. Doosan originally cataloged this part under number DWMB314046. This aftermarket replacement bearing supports the vertical movement of the mast roller within the channel. The bearing's plain mechanical function is to reduce rotational resistance as the roller travels along the mast surface. A common failure consequence is that a seized bearing can lead to roller flat-spotting and eventual mast binding. The bearing is a standard roller-type component without seals or flanges. Verify the serial number or application, then call (562) 693-7748.
