When implementing a linear guide or actuator into a system, you will likely have high expectations for how well the linear components will perform and how long they will last. Meeting those expectations, however, requires careful product selection and preventative measures against various threats such as wear, contamination, misalignment, impacts or shock. Neglecting these threats can result in crashes or premature failures that cost production time and money. When it comes to ensuring a long reliable lifetime and optimal performance, some best practices can go a long way. This article will describe the common threats linear motion devices can face and present tips to help you get the most from your guide.
