Needle Roller Bearings

Needle Roller Bearings (needle bearing) is a roller with a cylindrical roller bearings,

relative to its diameter, both the thin and long rollers. This is called needle roller.
Despite its smaller cross-section, still has a higher load bearing capacity, therefore,
especially suitable for the radial space-constrained occasions.

Needle contour surface in the proximal surface of the slight contraction.
Needle and raceway contact line results can be amended to avoid damaging
the edge of the stress.

 

Needle Roller Bearing characteristics and uses:

Equipped with a thin and long needle bearing roller (roller diameter,
length 3 to 10 times the diameter of generally not more than 5mm),
so the radial structure is compact, its diameter size and payload capacity compared
with other types of bearings the same time, diameter minimum,
especially for the radial bearing installation dimensions restricted results.
