“Linear actuators are designed to handle loads axially,” said Chad Carlberg, Product Line Specialist for Linear Actuators at Thomson. “One of the most common failure modes of linear actuators is side loading.” This occurs when a force exists that is perpendicular to the axis of rotation.
In the video, Carlberg describes how stroke length can affect design: “The longer the stroke length, the more susceptible an actuator is to binding or bending of the screw.” He goes on to explain how to increase the rigidity in an actuator: “A nut guide can be added for additional load support, and a design engineer could increase the ball screw diameter to add rigidity to the linear actuator.”
Thomson strives to continually innovate and lead the marketplace in linear motion solutions and share their application engineering and technical expertise. To that end, Thomson has authored a wide range of educational videos, webinars and technical white papers available now online to inform and guide design engineers, explain technology alternatives and simplify the linear motion component selection process.
