BEARING - MAST ROLLER (Doosan DWNI5911710H11)

DWNI5911710H11: A worn mast roller bearing can cause uneven roller wear and increased friction in the mast assembly. The Doosan catalog reference for this aftermarket replacement part is DWNI5911710H11. This bearing type supports the vertical movement of the mast rollers along the mast channel. A common failure consequence is binding or jerky mast movement during operation. During a routine service check, a technician may notice flat spots or roughness on the roller surface. The bearing's plain mechanical function is to reduce rotational friction between the roller and its mounting shaft. Verify the serial number or application, then call (562) 693-7748.
