ULTRAN RODLESS CYLINDER Size/Application Considerations Each bore size for the Bimba Ultran rodless cylinder has specific load carrying capabilities. These capabilities can be enhanced by externally supporting the load or by ordering the internal cushion option or external shock absorbers. The load should always be guided and supported for optimum life. Cushions or shock absorbers will also increase cylinder life when used properly. Use the following procedures to determine the requirements for specific applications. NOTE: Exceeding the load can cause the carriage and piston to decouple. RADIAL LOAD AXIAL LOAD MOMENT ARM (DIST ANCE FROM THE CENTER) 9/16" 1-1/4" 2" 1-1/2" 1-1/16" 7/8" 3/4" 7/16" 5/16" RADIAL LOAD vs STROKE LENGTH* GRAPH C *Stud mount only. Consult factory if pivot mounted. 9/16" 1-1/4" 2" 1-1/2" 1-1/16" 7/8" 3/4" 7/16" 5/16" AXIAL LOAD vs MOMENT ARM GRAPH D 1. Check radial load requirements. Graph C, Radial Load vs. Stroke Length, shows the maximum radial load the cylinder will support for a specific bore size and stroke length. If your radial load requirements fall above the curve, the load must be externally supported. 2. Check axial load requirements. Graph D, Axial Load vs. Moment Arm, shows the maximum axial load the cylinder will support for a specific bore size and moment arm length. If your axial load requirements fall above the curve for the specific bore size, the load must be externally supported. 3. Check End-of-Stroke Velocity and Load Requirements . From Graphs E through H, Velocity vs. Load, choose the graph for your Ultran model and mounting position. If your velocity and load requirements fall above the curve for the specific bore size, you will need internal cushions or external shock absorbers to decelerate the load without causing the carriage and piston to decouple. 4. Maximum Velocity. If cylinder speed will exceed 20 in/sec or cycle rate will exceed 15 per minute, special application considerations may be required. Please consult your local distributor. Internal Cushions . From Graphs I through L, Velocity vs. Load for Cushions, choose the graph for your Ultran model and mounting position. If your velocity and load requirements fall above the curve for the specific bore size, you will need external shock absorbers to decelerate the load. External Shock Absorbers. Choose from Graphs EE through RR, Velocity vs. Load for Shock Absorbers , for your bore size. Choose model LS, SS or HS based on your velocity and load.
