The Difference Between Composite Bearings And Rolling And Needle Rolling Bearings

What is needle roller bearing
Needle bearing  is a roller bearing with cylindrical roller, relative to its diameter, the roller is thin and long.This type of roller is called a needle roller.Despite having a small section, the bearing still has a high load bearing capacity.
Classification of needle roller bearings
Open type stamped outer ring needle roller bearings, closed stamped outer ring needle roller bearings, needle roller bearings with inner ring and without inner ring needle roller bearings/needle roller bearings without inner ring and cage, full needle roller bearings with and without cage.
The role of needle roller bearings
Needle roller bearings are equipped with thin and long rollers (the length of the roller is 3~10 times of the diameter, the diameter is generally not greater than 5mm), so the radial structure is compact, the inside diameter size and load capacity of the same with other types of bearings, the outer diameter is the smallest, especially suitable for the radial installation size of the limited supporting structure.Needle roller bearings according to the use of different occasions, processing accuracy and surface quality should be combined with bearing ring, purpose.

The difference between composite bearings and rolling and needle rolling bearings
There are significant differences between composite bearings and rolling bearings, so they can not be used interchangeably.
1. Rolling bearings, because of their complex multi-component design, precise structure and precise installation, are often much higher than the price of composite bearings.
2. Rolling bearings are more suitable for applications requiring precise shaft position and or very low friction.
3. composite bearings, due to its greater contact area and adaptability, can provide higher load bearing capacity and high impact load and end concentrated load tolerance.
4. Composite bearings make up for the dislocation better than partial rolling bearings to reduce the impact of the concentrated load at the end.
5.composite bearings using ultra-thin single design, can reduce the shell size, to a large extent to save space and reduce weight.
6. Composite bearings have stronger resistance to reciprocating motion and can prolong the life of bearings.
7.composite bearings at high speed and too low load operation will not be damaged by the sliding of the rolling body, and has excellent damping performance.
