Description

This needle roller bearing has a closed end drawn cup design, giving it a compact axial length while providing a fixed shoulder that seals off one side of the assembly. The outside diameter is 13.0 mm and the net mass is 4.56 g, making it suitable for lightweight, space-limited installations. It permits a limiting speed of 26500 1/min and a reference speed of 20200 1/min, allowing operation at high rotational speeds within these bounds. The closed end eliminates the need for a separate end cover on one side, simplifying installation where axial space is restricted. As the bearing is supplied without sealing, external protection or a housing arrangement must provide contamination control, and lubrication needs to be maintained through the open side. The drawn cup construction keeps radial section height low while still accommodating the full complement of needle rollers for load-carrying capacity within the stated speed limits.
