💡 What is a linear bushing used for in linear slide units and automation? A linear bushing supplies guided, low-friction linear motion support for shafts and rails in motion systems. Here's why they are handy on machines and motion assemblies: - Smooth, accurate linear slide unit motion for CNC, robotics, 3D printers and automation - Sealed ball bearing-style protection reduces contamination and maintenance needs - High carbon steel options provide solid load capacity; resin retainers lower noise and friction - Can pair with ceramic rolling elements or linear rails for high-performance applications
