💡 What is a pillow block bearing used for in conveyor and shaft support applications? Pillow block bearings are a handy way to support and align rotating shafts using a sealed ball bearing insert and easy relubrication access. - Provides stable shaft support and alignment for conveyors, fans, pumps and motor shafts, reducing wobble and wear. - Sealed ball bearing inserts and contact seals keep grease in and contaminants out for longer service life. - Cast iron PA204 housings with tapped bases simplify mounting; set-screw locking and 1/4-28 UNF grease fittings make maintenance quick. - Ideal for general-purpose industrial use, linear slide unit setups and retrofit shaft support where a single 20mm bearing is required.
