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

Date:2016-07-27 Author: Click:

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 needle roller bearings, the bearing capacity is limited to the installation size on the supporting structure. The journal surface is quenched into a rolling surface, and the bearing is pressed into the valve seat hole without axial positioning. Install the bearing to an appropriate amount of grease, usually. After assembly, there is no need to lubricate the end cover at the supporting end of the BK journal bearing, which has a sealing effect and can withstand 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 restricts the radial installation size. According to the use of different occasions, the machining accuracy and surface quality of the bearing ring, use the combination.


       Needle roller bearing is a very important mechanical part. Generally, it is used in many mechanical equipment. Therefore, it is widely used. Because it is easy to use and maintain, it has attracted the favor of many merchants. It is used in industrial production. In general, mass production is used.
