Size/Application Considerations (MCHL) Radial Moment Load (Mr) SKETCH B Radial Moment Axial Moment Cross Moment SKETCH C SKETCH D SKETCH E Fr L H Fa L H Fc Lc Ma Mr Mc An unbalanced radial or side load applied to the system. The center of the radial load must be outside the span of the guide shafts, or the center of the side load must be at some point other than the center of the guide shafts to cause a radial moment loading condition. Axial Moment Load (Ma) An axial (same as the direction of actuation) load applied to the system, where the center of the load is at some point other than the center of the guide shafts. The load must also be between the span of the guide shafts to be a pure axial moment loading condition. Cross Moment Load (Mc) An axial load applied to the system, where the center of the load is at some point outside of the span of the guide shafts. Sketches C, D, and E demonstrate how a force is applied to a moment arm to produce the moments shown in Sketch B. Use the equations below to determine the actual moments created by your application. The results of each calculated moment should be compared to the maximums listed in the table. (If the actual moments are greater than the listed maximums, then the load and moments should be re-evaluated.) Radial Moment = Mr = Fr x (L+H) Axial Moment = Ma = Fa x (L+H) Cross Moment = Mc = Fc x (Lc) A magnetically coupled rodless high load guided cylinder can withstand compound moments but the maximum allowable will be determined by the total percentage of the axial, radial and cross moments. The equation below will determine the compound moment percent based on the total moments. The compound moment percent must not be greater than 100. (If the compound moment percent is greater than 100, then the load and moments should be re-evaluated.) M compound % = 100 x ( Mr + Ma + Mc ) < 100% Mr max Mc max Ma max
