MX80S Series Product Manual13 Parker Hannifin CorporationEMN Automation - ParkerIrwin, PennsylvaniaMX80S Series Technical DataThe useful life of a linear table at full catalog specifications is dependent on the forces acting uponit. These forces include both static components resulting from payload weight, and dynamic com-ponents due to acceleration/deceleration of the load. In multi-axes applications, the primary posi-tioner at the bottom of the stack usually establishes the load limits for the combined axes. Whendetermining load/life, it is critical to include the weight of all positioning elements that contribute tothe load supported by the primary axis. The life/load charts are used to establish the table liferelative to the applied loads.Load-Life All TravelsMoment Load – Life CurvesThe effect of moment loading on the bearing life is dependent upon load and lever arm. The leverarm in this case is measured from the center of the surface of the table to the point where the loadis applied. For dynamic loading, use the distance from the center of the table to the center of massof the load. The Life-Load charts show curves for various lever arm lengths (units in [mm]). NotePitch moments and Yaw moments use the same curves.Pitch Moment LoadingRoll Moment LoadingYaw Moment LoadingLife vs Normal or Side load10001000010000010000000 1 2 3 4 5 6 7 8Load (kg)Life (km)T01T02T03T04
