💡 What is a spherical bushing used for in industrial bearing housings and linear slide units? Spherical bushings are handy plain bearings that accept shaft misalignment and heavy radial loads while keeping things running smooth. - They let shafts pivot inside housings and pillow blocks to reduce wear and handle misalignment. - Great for heavy-load steel-on-steel setups, high-temp service to 180 °C, and as an alternative to sealed ball bearing or ceramic options. - Commonly used with linear slide units, bearing housings, and industrial machinery where rugged reliability matters.
