💡 What is a pillow block bearing used for in industrial and high-temp setups? A handy support for rotating shafts that keeps a sealed ball bearing protected while allowing relubrication when needed. - Supports shafts, linear slide units, and conveyor rollers with sealed ball bearing protection. - Common in conveyors, fans, and gearbox mounts where relubrication and set-screw locking matter. - Choose cast iron housings and C4 clearance inserts for high-temp or slightly misaligned shafts.
