Pillow block roller bearing units consist of a tapered roller bearing mounted in a non-split type E dimensions housing that can be bolted to a support surface. This variant has a two-bolt base and set screw locking, holding the shaft firmly against the inner ring of the bearing. The units are sealed and lubricated and ready to use. This assortment of units covers a wide range of requirements, in inch dimensions.
