BEARING - MAST ROLLER (Doosan DWYT5200453-69)

DWYT5200453-69: A worn mast roller bearing can cause uneven roller movement and accelerated wear on the mast channel surfaces. This aftermarket replacement part references the Doosan catalog number DWYT5200453-69. The bearing type supports the roller as it travels along the mast channel, reducing friction during vertical movement. A failed bearing may produce a grinding noise or cause the roller to seize, leading to mast binding. Keeping the bearing in sound condition helps maintain smooth roller travel and consistent mast alignment. Verify the serial number or application, then call (562) 693-7748.
