The Difference Between Composite Bearings And Needle Roller Bearings

What is Needle roller bearings

Needle roller bearings are roller bearings with cylindrical roller, relative to its diameter, the roller is thin and long. This type of roller is called a needle roller. Although has the small section, the bearing still has the high load bearing capacity, the needle roller bearing is equipped with the thin and the long roller, therefore the radial structure is compact, its inside diameter size and the load capacity is the same as other types of bearings, the outer diameter is the smallest, especially suitable for the radial installation size is limited the supporting structure.

Characteristics of Needle roller bearings

Needle roller bearings are equipped with thin and long rollers, so the radial structure is compact, the inside diameter size and load capacity are the same as other types of bearings, the outer diameter is the smallest, especially suitable for the radial installation size of the limited supporting structure.

Application of Needle roller bearings

Roller needle roller bearing is suitable for printing machinery, forage machinery, agricultural machinery, CNC equipment guide rail roller, conveyor line, etc.

The difference between composite bearings and needle roller bearings

There are significant differences between composite bearings and needle roller bearings, so they can not be used interchangeably.

1. Because of their complex multi-component design, precise structure and precise installation, are often much higher than the price of composite bearings.

2. Needle roller 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.

Compared with rolling bearings, composite bearings do not contain moving parts inside, so the operation is more quiet, and the speed is almost unlimited in a properly lubricated system.

9. Composite bearing installation is simple, only need to be machined shell, compared with the rolling bearing will almost not cause damage to the accessories.

10.Compared with standard rolling bearings, non-metallic composite bearings have stronger corrosion resistance.

11. Composite bearings can be dry operation, without additional lubricant system, lubricant and maintenance equipment downtime and other costs.

12.Composite bearings can be dried at high temperature and in the presence of pollutants.
