Abstract

Non-rotating tubular wellbore cleaning devices are described which include a central tool mandrel with radially surrounding stabilizers and a cleaning member subassembly. A rotational bearing is provided that is partially radially recessed, thereby improving the overall strength of the cleaning device.
