Guided motion is an important feature found in automated machinery and equipment. Motion system components can enable the movement of heavy loads, or allow for equipment to be designed for adjustability and allow for a variety of machine functions or operational tasks. Motion products are engineered for specific conditions such as load direction, load capacity, or chemical compatibility. They are typically designed to carry loads in controlled service conditions which are clean, free of debris and well lubricated. After several months of use, these ideal operating conditions are rarely a reality for production machinery.

Guide wheels can routinely achieve travel life of one million cycles or higher when these specified load capacities are observed.
