![]() Fortunately, most linear guides and actuators can be modeled as beams, and their deflection can be calculated using common beam deflection equations. It’s important to check the application and ensure that this maximum deflection is not exceeded. Products that may be mounted with only end supports, such as linear shafts or actuator assemblies, or in a cantilevered orientation, such as telescoping bearings, will typically have a specification for maximum allowable deflection. In these cases, deflection (due to the component’s own weight and due to applied loads and forces) can affect the running properties of the bearings and cause poor operation, in the form of premature wear and binding. There are many situations in motion applications where a linear guide or actuator isn’t fully supported along its entire length. ![]()
