💡 What is a pillow block bearing used for in conveyor, gearbox, and linear slide unit applications? A handy support bearing that locates shafts, takes radial loads, and lets you service bearings without moving the whole machine. - Supports rotating shafts and absorbs radial loads using a sealed ball bearing design for long life and low maintenance. - Common in conveyor systems, gearboxes, roller drives, and linear slide unit assemblies where set-screw locking is preferred. - Allows on-shaft locking with set screws and easy relubrication via a 1/8-27 NPT fitting, and handles heavy-duty temps to 212 F.
