The 4120 is a thrust ball bearing supplied by DALUO under our own designation. It is dimensioned to the 100x150x41 mm envelope (bore 100 mm, outer 150 mm, width 41 mm). Each unit is produced to the original mounting and load envelope, so it drops straight into the applications the 4120 was designed for.

- Consistent re-orders. The same designation arrives with the same tolerances, order after order.
Applications
The 4120 is commonly fitted where a thrust ball bearing has to carry axial load in a compact space: gearboxes, pumps, motors, conveyors, agricultural machinery and general industrial drives. If you are replacing an existing unit, confirm the shaft and housing fits from the table above.
