💡 What is a pillow block bearing used for in industrial shaft support and conveyor systems? Pillow block bearings support rotating shafts and make maintenance and shaft swaps easier. - Support and align shafts in conveyors, rollers and linear slide units using sealed ball bearing inserts for contamination resistance. - Secure shafts with eccentric collars or set-screw options for quick replacement and accurate locking. - Enable scheduled relubrication via 1/8-27 NPT fittings to extend service life in heavy-duty, high-temp or dusty conditions.
