The 6304ZZNR is a deep groove ball bearing supplied by DALUO under our own designation. It is dimensioned to the 20x52x15 mm envelope (bore 20.000 mm, outer 52.000 mm, width 15.000 mm). Each unit is produced to the original mounting and load envelope, so it drops straight into the applications the 6304ZZNR was designed for.

Applications
The 6304ZZNR is commonly fitted where a deep groove ball bearing has to carry combined radial and 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.
