💡 What is a linear bushing used for in a precision linear slide unit? A linear bushing supports and guides shafts to deliver smooth, accurate linear motion with minimal play. Here’s why it matters: - Provides low-friction shaft guidance for repeatable positioning in precision linear slide units and linear slide applications. - For dusty or high-speed setups, sealed ball bearing or ceramic options offer better contamination control and higher RPM performance. - Commonly used in small robotics, pick-and-place modules, CNC axes, and optical equipment where compact, accurate shaft support is needed.
