Radial support for shafts is provided through a drawn cup needle roller bearing with an open end design, outside diameter 22.0 mm and width 16.0 mm, manufactured to DIN 618/ISO 3245. The bearing has a net mass of 15.3 g, a limiting speed of 15600 1/min and a reference speed of 11600 1/min. The open end construction leaves both sides accessible, which allows the shaft to pass through the bearing without axial obstruction. As the bearing is supplied without sealing, lubricant must be applied and retained through the surrounding housing design, and protection against contamination has to be provided externally. The thin-walled drawn cup construction keeps radial space requirements low while sustaining the stated speed ratings.
