💡 What is a pillow block bearing used for in high-temperature machinery? Pillow block bearings provide supported rotation for shafts under heat stress. - They keep shafts aligned and reduce friction in hot environments, acting like a sealed ball bearing support. - Good for conveyor systems, linear slide unit guides, and driven shafts in ovens or dryers. - Choosing units with silicone contact seals and C4 clearance helps longevity and maintenance ease.
