This needle roller bearing guides a yoke-type track roller with a particularly thick-walled outer ring, a full complement needle roller set and an inner ring. Bore diameter is 20.0 mm, outside diameter 47.0 mm, and net mass is 250.0 g. Axial guidance of the outer ring is provided by plastic axial plain washers together with contact washers, giving a three-stage sealing arrangement with plastic axial plain washers fitted on both sides (PP). The thick-walled outer ring and full complement needle roller set allow the bearing to carry high radial loads in a compact envelope, making it suitable for direct rolling contact on a track or cam surface. The three-stage plastic washer sealing keeps contaminants out of the roller set while retaining lubricant, so the bearing can operate without an additional cage-related grease loss path. Axial guidance built into the outer ring eliminates the need for separate axial location elements, simplifying installation on the mating shaft or pin.
