This needle roller bearing uses a drawn cup design with an open end, providing a compact radial section for applications where installation space is limited. Outside diameter is 11.0 mm and width is 9.0 mm, with a net mass of 2.49 g. The limiting speed reaches 33000 1/min, while the reference speed is 26500 1/min, allowing operation at higher rotational speeds within a small envelope. The bearing is supplied without sealing, so lubrication and contamination protection must be provided externally, and the open-end construction allows shaft insertion from one side during assembly. The thin-walled drawn cup keeps radial dimensions minimal while the needle rollers give a high load-carrying capacity relative to the bearing size, making it suitable where a slim, high-speed radial bearing is required and where housing bore tolerances match the standard HK series.
