Drawn Cup Needle Roller Bearings of the HK series are needle roller bearings with chipless manufactured thin-walled outer rings. Drawn Cup Needle Roller Bearings are open on both sides. Essential features of the HK series are the extremely low section height and the high load carrying capacity. They are primarily used if the housing bores cannot be designed as raceways for needle roller and cage assemblies and in case of aiming at particularly space-saving and efficient storage. HK-Drawn Cup Needle Roller Bearings are easy to assemble, since they are simply pressed into the housing bore and do not require any further axial fixation.
