When properly sizing and selecting a DURATRK™ rodless cylinder for your next cylinder application, the goal is to determine the amount of cylinder force necessary to provide a cost-effective and efficient solution.
DURATRK™ rodless cylinders are available in bore sizes from 18 mm up to 63 mm and are available in stroke lengths from a few inches to 16 feet. Customers report that cylinders such as the Bimba Ultran® UB, UBS Band Cylinder Norgren, and Lintra Plus Rodless Cylinder have lead times as long as eight weeks. DURATRK™ rodless cylinders are available in a fraction of the time–one week. With that flexibility and customization comes the importance of properly calculating and sizing the perfect rodless cylinder for your application:
Calculate the Cylinder Force
The first thing to consider in sizing a DURATRK™ rodless cylinder is the cylinder force required for your application. If your application is horizontal sliding orientation, use the following equation:
Load Weight x Coefficient of Friction (of the sliding mechanism)
Next, compare that result to the following:
Cylinder Bore Size x Pressure
This will help you determine the force output of the cylinder. Make sure it equals your required cylinder force plus an additional 20% to account for system losses.
Consider the Stroke Length of the Cylinder
You can refer to this chart for maximum load vs stroke length requirements. Additional tube supports are optional and available if added cylinder support is necessary.Consider the Internal Cushions for the Cylinder
Cylinders are provided with internal adjustable cushions. We’ll want to refer to the load velocity vs load weight to determine if the cylinder cushions are adequate for your application. If more cushioning is necessary, we can simply install external shock absorbers to the configuration.Take Advantage of DURATRK’s™ Broad Product Line
