ABSTRACT:
This invention relates to an improved pillow block characterized by a cast body containing a main bore for housing an antifriction bearing and cast bolt-receiving slots for mounting same and for attaching endplates thereto that do away with the need for drilled and tapped holes. The endplates are cut from common sheet materials and gang-drilled to provide the apertures that accept the bolts used to assemble same onto the opposite faces of the body with an O-ring therebetween to establish a fluid-tight seal. In like manner, a hole cutter is used to cut rather than drill a central hole for passing the rotating element to be journalled in the bearing.
