    [VIDEO] Actuator Sizing: PNEUSA®

    Posted by Troy Branham on Sep 5 ,2018

    The PNEUSA® is a unique cylinder design using an internally enclosed cable cylinder based on our original cable cylinder sealing technology. This provides complete protection of the internal sealing components from harsh environments, which means you can use the PNEUSA® in all types of applications!

    But finding the perfect fit for your application isn’t always the easiest job. Our VP of Engineering and General Manager, Chad Randleman, breaks down how to size a PNEUSA® rodless cylinder for your rodless cylinder application:

     

    Step 1: Calculate Cylinder Force Required

    For horizontal sliding applications, use the following equation:

    Load weight x Coefficient of friction of the sliding mechanism

    Step 2: Determine Adequate Cylinder Size

    To accomplish this, we use the following equation:

    Cylinder bore size area x Pressure applied to the cylinder

    You’ll want that force to equal your load weight plus an additional 20% to account for losses.

    Step 3: Consider the Stroke Length of Your Application

    If the cylinder will be designed to support and guide the load with the provided guiding carriage, then you’ll want to refer to the maximum load versus stroke curve of the cylinder to make sure it can handle the weight. Additional tube supports are available if necessary.

    Step 4: Consider the Internal Cushioning of the Cylinder

    Cylinders are provided with internal adjustable pneumatic cushions to decelerate and dampen the stroke at the end of travel. We’ll want to refer to the maximum load versus velocity chart to see if it falls within the acceptable limits of the cylinder cushions.

    Now that you know how to size your PNEUSA® rodless cylinder, your application should work as smoothly as possible! But, as always, make sure you contact us if you have any questions.
