American Roller Bearing ATXW222H Journal Bearing

The American Roller Bearing ATXW222H is a precision journal bearing designed to support rotating shafts in heavy‑duty machinery. It features an inner diameter of 4-7/16 in (112.6 mm) and an outer diameter of 200 mm (7.874 in), sized for applications that call for an ATXW222H‑class journal bearing. As a journal bearing, it relies on a lubricating film to minimize metal-to-metal contact and sustain load while allowing smooth rotation. This model is part of American Roller Bearing’s line of journal bearings and is suitable for retrofit or new installations where exact bore and outer dimensions are required. When replacing, confirm that your shaft fits a 4.4375 in bore and that the housing accommodates a 200 mm outer diameter, and align your lubrication method with your system’s design—whether oil or grease lubrication is specified for your equipment.
