The 1004 is a thrust ball bearing supplied by DALUO under our own designation. It is dimensioned to the 20x45x23 mm envelope (bore 20 mm, outer 45 mm, width 23 mm). Each unit is produced to the original mounting and load envelope, so it drops straight into the applications the 1004 was designed for.

Applications
The 1004 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.
