💡 What is a linear bushing used for in CNC tables and automation? It provides smooth, guided linear motion on shafts and keeps setups accurate and reliable. This short answer explains why a bushing is a handy choice for many motion systems: - Improves linear slide unit alignment and repeatability for CNC machines and robotic axes - Reduces friction and wear on shafts compared with plain sliding surfaces, extending component life - Works well in automation where compact, high-carbon steel open bushings are preferred over sealed ball bearing or ceramic options
