This needle roller bearing carries a drawn cup design with open ends, manufactured to DIN 618/ISO 3245. Outside diameter is 28.0 mm, width 12.0 mm, and net mass 14.784 g. The limiting speed is rated at 11700 1/min, with a reference speed of 8900 1/min. The bearing is supplied without sealing, so the raceway remains exposed and relies on external protection from the surrounding housing. The open-end drawn cup construction allows a compact radial section for applications where axial space is limited. As no shielding is fitted, lubrication and contamination control must be provided by the housing design or separate sealing arrangement. The HK2212-B accommodates radial loads within its compact envelope while requiring precise shaft and housing fits to maintain the drawn cup's thin-wall geometry.
