💡 What is a crossed roller bearing used for in rotary stages and linear slide units? Crossed roller bearings provide compact, rigid rotation and are handy in precision motion systems. - Ideal for rotary stages, indexing tables, turntables, and compact linear slide unit applications needing high rigidity and accuracy. - Sealed construction helps keep out dust and debris, similar to sealed ball bearing options for protected environments. - Preload and separator design reduce play and improve repeatability for machine tools, inspection gear, and optical positioning systems.
