Selection and ordering data
J hubs or jumbo hubs are used where the shaft diameter is greater than the maximum bore diameter of the N hub. Because of the
larger hub core diameter "ØND1", the J hub cannot be used as a B hub, i.e. the hub core diameter is greater than the inside diameter
of the spacer tube and cannot project into the spacer. The J hub can be combined with any spacer.
