A linear bearing, also known as a linear ball bush or bushing, is a bearing that runs on a hardened linear shaft to help guide or support the movement of a component in a linear fashion. A cost effective method of achieving linear motion where the loads are light enough to not need conventional linear guides or where the guide can only be supported at the ends and not over the entire length.
