NAV4920 Needle Roller Bearing

 Needle roller bearing

1.  They accommodate both radial and axial loads in both directions and are suitable for high rotational speeds.

2.  Our needle roller bearing has many types. They can meet all needs.

4. Needle roller bearings: Low-notice, high speed, suitable for the motor bearing and automotive bearings.

 
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 surfaces 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 a needle cage which orients and contains the needle rollers, the needle rollers themselves, and an outer race(sometimes housing itself).

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.

Full complement bearings have solid inner and outer rings and rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have extremely high radial load carrying capacity and are suitable for particularly compact designs.

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 operates 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.
