Extended version of the 7003 allowing for use with smaller hub diameters due to the reduced shaft and hub pressures. 7004 ECOLOC Is the extended design of series 7003 ECOLOC. Here, due to the low pressure the hub can be designed very cost-effective (small outer diameter). Explanations L = Overall width L 1 = Overall width (without screws) L 3 = Clamping length d = Inner ring diameter D = Outer diameter
