BEARING - MAST ROLLER (Doosan DWMB910946)

DWMB910946: A worn mast roller bearing can cause uneven roller movement and accelerated wear on mast channels. This aftermarket replacement part references the Doosan catalog number DWMB910946. The bearing type supports the roller assembly that guides vertical travel along the mast structure. 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 that contaminates other mast 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.
