Needle roller bearing is a kind of roller with cylindrical roller bearing

Needle roller bearing is a kind of roller with cylindrical roller bearing. Relative to its diameter, the roller is thin and long. This is the so-called needle roller. Although the bearing capacity of a smaller section still has a higher bearing capacity, the needle roller bearing has a thin and long roller. Therefore, the radial structure is compact.

For the needle roller bearing, the bearing capacity of the bearing is limited by the size of the device in the supporting structure. The surface of the journal is quenched into a rolling surface, and the bearing is pressed into the valve seat hole without axial positioning. In the device bearing to an appropriate amount of smooth grease, under normal conditions. After assembly, it is no longer necessary to smooth the end cover of the supporting end of the BK journal bearing, which has a sealing effect and can accept small axial movement.

Equipped with a thin and long bearing roller, so the radial structure is compact, the diameter size and load capacity are the same as other types of bearings, the smallest diameter, especially the support structure that limits the size of the radial device. According to the application conditions in different places, the machining accuracy and appearance quality of the bearing ring, the combination is used.

The needle roller bearing is a very important mechanical part. It is commonly used in many mechanical equipment, so its application is very common. Because its use and maintenance are very convenient, it has absorbed the love of many merchants and is used in industrial consumption. In general, they are consumed in large quantities.
