Needle bearing (needle with cylindrical roller according) is the roller bearings, relative to its diameter, roller is fine and long. This roller called needle.
Although it has a small section, bearing still had high load to bear ability, therefore, especially suitable for radial the place with limited space.
Needle contour surface near end place slightly contraction. Needle and groove line contact modified results can avoid to produce destructive effect-edge stress.
