    [VIDEO] Actuator Sizing: Magnetically Coupled Cylinder

    Posted by Troy Branham on May 30 ,2018

    When searching for the perfect magnetically-coupled cylinder for your next rodless cylinder application, there are certain observations you must make.

    In our new video, Chad Randleman, VP of Engineering & General Manager of W.C. Branham, explains how to do just that:

     

    Calculate Required Cylinder Force

    The first thing to consider is the required cylinder force. The cylinder force can be determined by multiplying the bore area of the cylinder size times the pressure applied to the cylinder.

    For Horizontal Sliding Applications

    To determine your required application force for a horizontal sliding application, take the load weight times the coefficient of friction of the guiding mechanism.

    For Vertical Applications

    The required application force for vertical applications is simply the weight of the load.

    Calculate the Stroke Length

    The next thing to consider is the stroke length. Magnetically-coupled cylinders are available with a stroke length anywhere from a few inches up to approximately 26 feet.

    Our MAGTEC cylinders, for example, are designed to only provide the moving force and do not offer any guiding or load support. External guiding mechanisms would be required.

    Consider the Cylinder’s Internal Adjustable Cushions

    Internal adjustable cushions, like the ones available with our MAGTEC-magnetically-coupled cylinders, cushion and decelerate the load at the end of stroke.

    Refer to the load vs. velocity chart, and determine if your application is within the guidelines. If not, external shock absorbers can be added to your applications.
