💡 What is a spherical bushing used for in linear slide units and pillow block mounts? A spherical bushing provides self-aligning support for rotating shafts and absorbs radial loads in setups where a sealed ball bearing or ceramic insert might not be the best fit. Quick summary: - Offers self-aligning support for shafts in pillow block and linear slide unit assemblies - Handles shock and high radial loads where steel-on-steel contact is acceptable - Useful in high-temp or exposed environments up to 180 °C and as an alternative to sealed ball bearing or ceramic solutions
