Opened and closed drawn cup needle roller bearings are needle roller bearings with the smallest radial construction height consisting of a thin walled non-cutting outer rings and needle cages. Cage with needles allows rolling placing with high load capacity and also provides excellent function of the bearing even at high speeds and long lubrication intervals thanks to the large spaces for grease.

These drawn cup needle roller bearings, if not placed directly on the hardened shafts, may be combined with inner rings LR or IR. Inner rings belonging to specific bearings are indicated in the dimension tables.

 

Drawn cup needle roller bearings are supplied in these design:

  • HK – opened drawn cup needle roller bearings with a cage
  • BK – drawn cup needle roller bearings with a cage, one-side closed

 

In comparison with opened drawn cup needle roller bearings the closed drawn cup needle roller bearings type do have closed bottoms and are suitable to close the placing at the end of the shaft and to capture the start-up forces.
