The Difference And Application Of Cylindrical Roller Bearing And Needle Roller Bearing

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 and application of cylindrical roller bearing and needle roller bearing

The differences between cylindrical roller bearings and needle roller bearings are as follows:

1. The rolling body of cylindrical roller bearings is a tapered roller shaft; The rolling body of needle roller bearing is needle-like roller;

2. The structure of cylindrical roller bearings is larger than that of needle roller bearings.

3. In addition to the radial force, the cylindrical roller can also bear axial force, while the needle roller bearing can only bear radial force;

4. Cylindrical roller bearings are divided into single row, double row and multiple row, which are applied to different environments and occasions respectively;

5. The working speed of cylindrical roller bearing is higher than that of needle roller bearing;

6. Cylindrical roller bearings are generally made of high quality bearing steel and special steel; Thin-wall needle roller bearings are made of steel plates. 

Applicable occasions

In mechanical design, the size of the shaft is generally determined first, and then the rolling bearing is selected according to the size of the shaft. However, when the bearing is limited in the diameter direction of the machine, needle roller bearings, extra-light and ultra-light series of ball or roller bearings are selected; When the bearing is limited in the axial position of the machine, narrow or extra-narrow series of ball or roller bearings can be selected.

Centripetal needle roller and cage assembly, punch outer ring needle roller bearings, solid ring needle roller bearings, thrust needle roller bearings are widely used in automobile related information and engineering machinery variable speed transmission system, steering system, motorcycle engine connecting rod and other places, suitable for small space, large bearing capacity. 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 support results.

The price of Needle roller bearings

The price of Needle roller bearings is affected by many factors such as market, material and quotation. If you want to know the specific price of Needle roller bearings,please contact us to make enquiries.
