Standard Series KAAAAAAA^ The specific purpose of series MAV 6903 is the axial locking of other elements adjacent to hub (e.g. bearings) during tightening of locking assembly. The movement of outer ring of locking assembly generates an axial force which is transmitted to hub and, by means of flanges and spacers, to adjacent elements. Code: Ma: screws tightening torque Mt: transmissible torque with Fax=O kN Fax: transmissible axial load with Mt=O Nm Ps: contact pressure on shaft Ph: contact pressure in hub bore
