BEARING - MAST ROLLER (Doosan DWYT5200453-70)

DWYT5200453-70: A worn mast roller bearing can cause uneven roller movement and premature wear on the mast channel surfaces. This aftermarket replacement part references the Doosan catalog and carries the part number DWYT5200453-70. The bearing type supports the roller assembly that guides vertical motion of the mast sections. A plain mechanical function of this bearing is to reduce friction between the roller and its mounting shaft. A common generic failure consequence is that a seized bearing can lead to roller flat-spotting and jerky mast travel. During routine service, a technician may notice increased rolling resistance or audible grinding from the bearing area. Verify the serial number or application, then call (562) 693-7748.
