💡 What is a 2-bolt flange ball bearing used for in industrial mounts and linear slide units? A 2-bolt flange ball bearing provides compact, secure shaft support with a sealed, set-screw locked mount for rotating parts. Handy for quick mounts and replacements in machines: - Supports shafts in tight spots while protecting components with a contact seal and sealed ball bearing design. - Fits linear slide units, acts as a pillow block alternative, and works where set-screw locking is preferred. - Permits relubrication and standard-temperature operation up to 212°F (100°C), good for general industrial use.
