💡 What is a pillow block bearing used for? A pillow block bearing supports and locates rotating shafts on mounted equipment, keeping shafts aligned and protected. - Ideal for conveyors, fans, pumps, and linear slide units where sealed ball bearing protection is needed. - Eccentric collar types let you lock the inner ring quickly without set screws for fast shaft installation. - Handy features like 1/8-27 NPT relubrication fittings and double-lip contact seals reduce downtime.
