Needle bearings
|
Needle roller bearings are roller bearings with thin and long cylindrical rollers. Despite their low cross-sectional height, the bearings have a high load capacity and are therefore suitable for bearings where radial space is limited. The outer surface of the needle rollers is slightly curved towards the ends of the rollers. This enables a flexible line contact between the needle rollers and the raceways, which prevents damaging edge loads.

Needle roller bearings come either with an inner ring (NKI/NKIS/NA) or without an inner ring (NK/NKS/RNA). Needle roller bearings are also produced with double rows with internal dimensions of 40 mm and larger (RNA69../NA69..). Needle roller bearings with a seal on one side (RS) or on both sides (2RS) are available in limited quantities. |
