💡 What is a linear motion bearing used for? Linear bearings keep shafts moving straight and smooth in many machines. - They cut down drag so motors use less power during long prints or cuts. - The open style lets rails support the shaft from below in tight frames. - A four pack gives you enough units to finish a full axis setup right away.
