This series of needle roller bearings consist of a thin walled drawn cup outer ring and a needle roller and cage assembly which together form the bearing unit.
Drawn cup needle roller bearings are available with open ends (HK) or closed one end (BK). These bearings are also available in sealed one side (HK and BK) or sealed both sides (HK only).These bearings must be fully supported to ensure proper load carrying capacity and the bearings running surfaces must be hardened and ground, otherwise, a suitable inner ring must be used.The needle rollers of this series have a high load carrying capacity and a small sectional height. The hardened outer ring has ribs and together with the needle roller and cage assembly the complete bearing unit is formed.
