💡 What is a crossed roller bearing used for in precision rotary tables and linear slide units? A crossed roller bearing is a compact solution that supports combined radial and axial loads with high stiffness for precise rotation. - Ideal for rotary tables, turntables, and indexing heads where accuracy matters - Works well in linear slide units and goniometers as a precise shaft support - Preferred over sealed ball bearing when rigidity and preload accuracy are required - Compatible with ceramic rollers or sealed ball bearing setups for specialized low-friction needs
