💡 What is a spherical bushing used for in pillow block bearings and linear slide units? A spherical bushing lets shafts self-align while keeping seals and smooth motion under heavy radial loads. Quick intro: Handy in installs that need alignment and dependable sealing. - Accommodates shaft misalignment and reduces wear, acting like a sealed ball bearing replacement when needed. - Fits pillow block housings and linear slide units for radial load support and easier maintenance. - Works well in harsh environments where sealed, steel-on-steel durability and clearance control matter.
