BEARING - MAST ROLLER (Doosan DWD860244)

A worn mast roller bearing can cause rough carriage movement and uneven load handling. This aftermarket replacement part references the Doosan catalog and carries the part number DWD860244. The bearing type supports the roller assembly that guides vertical travel along the mast channel. A plain mechanical function of this bearing is to reduce friction between the roller and its mounting surface. A concrete generic failure consequence is that a seized bearing can produce metal debris, contaminating adjacent components. Keeping the bearing in sound condition helps maintain consistent roller alignment during operation. Verify the serial number or application, then call (562) 693-7748.
