ULTRAN SLIDE RODLESS CYLINDER Size/Application Considerations Fr L H Radial Moment Sketch B Fa L H Axial Moment Sketch C Fc Lc Cross Moment Sketch D Moments About the Carriage: The table below gives the maximum allowable moment an Ultran Slide will support. There are three different directions that the moment can be applied (see Sketch A). Maximum Allowable Moment (in-lb) Mc Mr Ma Sketch A Sketches B, C, and D demonstrate how a force is applied to a moment arm to produce the moments shown in Sketch A. 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 evaluated using the next larger Ultran Slide.) Radial Moment = Mr = Fr x (L+H) Axial Moment = Ma = Fa x (L+H) Cross Moment = Mc = Fc x (Lc) An Ultran Slide 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 evaluated using the next larger Ultran Slide.) M compound% = 100 x ( M r + M a + M c ) 100% M r max M a max M c max Radial Axial Cross Bore H Mr max. Ma max.
