Timken 48290-48220 Tapered Roller Bearing

Timken 48290-48220 Tapered Roller Bearing — 140mm Bore Heavy Industrial Bearing for Saudi Applications

The Timken 48290-48220 is a large-bore (139.7mm) tapered roller bearing set designed for heavy industrial shaft applications requiring high radial and axial load capacity. The 48290-48220 is specified in large industrial equipment — mining machinery, heavy gearboxes, steel mill equipment, and large rotating equipment in Saudi Arabia's extractive and heavy manufacturing industries.

Saudi Arabia's mining and quarrying sector — operating across the Northern Border, Al-Madina, and Al-Qunfudhah regions — uses 48290-48220 in primary crushing equipment, heavy conveyor drives, and large electric motor bearing replacement applications where shaft diameters exceed 130mm.

SABIC's steel and cement subsidiaries in Jubail and Yanbu also specify 48290-48220 for rolling mill work roll bearings and large pump shaft bearing arrangements in water treatment and steam generation facilities.

Applications

Mining Crushers: Primary gyratory and jaw crusher main shaft bearings in Saudi Arabian quarrying operations use 48290-48220 for extreme radial loads from rock crushing.

Steel Mill Rolling Equipment: Work roll and back-up roll bearing positions in Saudi steel hot rolling mills use 48290-48220 for combined radial and axial loads from strip threading.

Large Pump Shafts: Large diameter pump shafts in Saudi water utility and petrochemical facilities with shaft diameters around 130–150mm.
