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.
In that locking and locating pins may be sheared off by severe shaft misalignment, there is also disclosed a construction limiting self-alignment relative rotation between the cartridge and the housing to some predetermined amount.
