Drawn cup needle roller bearings HK2018 20x27x18mm DIN618 ISO 3245

Drawn cup needle roller bearings Drawn cup needle roller bearings are needle roller bearings without an inner ring which are placed directly on the shaft, which is why it is necessary for the running surface of the shaft to be polished and hardened. If this surface quality is given, drawn cup needle roller bearings are ideal for supporting high radial forces in a very confined space. The bearings can be pressed directly into the housing bore without further axial location, which makes mounting easy. The needle roller bearings are available in various dimensions and designs.
