Needle roller bearing
1. High precision and low noise
2. High quality and good price
3. Common models are large in stock
A needle roller bearing is a bearing which uses small
cylindrical rollers. They are used to reduce friction of a rotating
surface.
Needle bearings have a large surface area that is in contact with
the bearing outer surface compared to ball bearings. Additionally
there is less added clearance(difference between the diameter of
the shaft and the diameter of the bearing) so they are much more
compact. The typical structure consists of an inner race(or
sometimes merely a shaft), a needle cage which orients and contains
the needle rollers, the needle rollers themselves, and an outer
race.
Radial needle bearings are cylindrical and use rollers parallel to
the axis of the shaft. Thrust needle bearings are flat and use a
radial pattern of needles.
Needle bearings are heavily used in engine components such as
rocker arm pivots, pumps, compressors, and transmissions. The drive
shaft of a rear-wheel drive vehicle typically has at least 8 needle
bearings(4 in each U joint) and often more if it is particularly
long, or opearates on steep slopes.
Additional clarification of Needle Roller. According to "Marks
Standard Handbook for Mechanical Engineers", a needle bearing is a
roller bearing with rollers whose length are at least four times
their diameter.
