💡 What is a linear bushing used for in CNC linear slide units and automation? It provides low-friction, precise shaft guidance for linear slide unit setups and motion systems. - Helps guide shafts and reduce wear in linear slide unit applications, improving repeatability and accuracy - Often preferred over sealed ball bearing cartridges when space is tight or when side access is required - Works alongside sealed ball bearing or ceramic options in mixed systems for tailored load and corrosion needs - Handy for light automation, CNC tables, robotics, and pick-and-place mechanisms where a compact linear guide is needed
