💡 What is a spherical bushing used for in linear slide unit or pillow block bearing applications? A spherical bushing gives you a low-friction pivot that handles misalignment and heavy loads, making it handy on shafts and slides. - Commonly used to accommodate shaft misalignment in linear slide units and pillow block setups for smoother motion and less wear. - Works alongside sealed ball bearing or ceramic bearing systems when you need a sturdy metal-on-metal option. - Helps distribute heavy static and dynamic loads in industrial machinery and automation gear.
