Needle bearing
Needle bearing is a cylindrical roller bearing, relative to its
diameter, the roller is both thin and long this roller called
needle although has a smaller section, bearing still has a higher
load bearing capacity, needle bearing is equipped with thin and
long roller (roller diameter D 5mm,L/D 2.5,L is the length of
roller), so the radial structure is compact, and its inner diameter
size and load capacity are the same as other types of bearings,
while the outer diameter is the smallest, especially suitable for
the radial installation size of the support structure is limited .
