Pillow Block and Flange Block Supports

They are sometimes needed to support long shafts or the ends of rotating screws.Joyce Ductile iron pillow blocks and flange blocks include self-aligning replaceable bearings that are pre-lubricated with lithium grease. They include steel retainers, and nitrile rubber seals with steel guards. They are suitable for use under normal duty operation.
