Abstract: An elongated, rectangular, bearing take-up frame has guide rails on the longitudinal frame members for guiding a slidably adjustable bearing block therebetween and an aperture in one end member midway between the guide rails for journalling and retaining a motion transmission screw nut. The frame is divided into two detachably connected portions so as to permit the lateral entry or removal of the bearing block and transmission screw and nut in a direction perpendicular to the axis of the bearing block.

Abstract: A bearing cartridge of integral construction comprising inner and outer races with sets of rollers therebetween and with an outer cylindrical configuration insertable and removable, as an integral unit, in and from a cylindrical opening in a housing or pillow block.

Abstract: Resilient, preferably elastomeric or plastic means of a low modulus of elasticity are located in the lubrication passageway of a bearing housing to seal with the bearing race and to insure passage of lubricant to a lubricant opening in the bearing race and thus into the bearing and to its anti-friction elements.

Abstract: A roller bearing cartridge and a method of making the same is disclosed. The cartridge is constructed with an outer race assembly constructed of two identical parts, centrally joined together, such that openings are provided for a locking or locating pin and for the passage of lubricant regardless of the type of housing in which the cartridge is used, which housings have lubrication fittings and cavities for locking or locating pins in locations which differ from one another.The locking and locating pins restrict relative rotation between the outer race which is constructed with an arcuate outer surface and the housing which has the opening defined by an arcuate surface to receive the cartridge. The restricted relative rotation is between the cartridge and the housing and is such to provide sufficient relative rotation to permit the bearing assembly to be self-aligning to accommodate shaft misalignment relative to the housing support.
