💡 What is a pillow block bearing used for? A pillow block bearing supports rotating shafts and keeps alignment in many machines. - It holds radial loads and keeps shafts steady in conveyors, fans, pumps, and linear slide unit setups. - A sealed ball bearing pillow block protects the bearing from contaminants and allows relubrication via a 1/8-27 NPT fitting. - For higher temp or specialty needs consider ceramic ball bearings or alternative inserts for longer life and lower friction.
