Needle bearing has high transmission efficiency, less heat generation, convenient lubrication and maintenance, and lubricant saving; However, due to the outstanding advantages of needle roller bearings, at present, needle roller bearings have developed into the main support type of machinery, and their applications are becoming more and more extensive.

The friction coefficient of the needle roller bearing is small, so the friction resistance and starting friction torque are small, and the power consumption is low;  the external dimensions have been internationally standardized, serialized and generalized, suitable for mass production, good interchangeability, easy installation, disassembly and maintenance;

Let's take a look at the advantages of needle roller bearings! The advantages of needle roller bearings:  Needle roller bearings are mainly used for large cranes and material lifting equipment such as shelves, forklifts, stackers, metallurgical industry, container front forks, cranes, etc.

The rigidity of the bearing can be improved by applying preload, which is very important for precision machinery; The bearing capacity of the radial and axial direction of the bearing is relatively large, and the accessories are highly replaceable. The internal clearance of the needle roller bearing is very small and the machining accuracy is high.Introduction to the advantages of needle roller bearings 　　
Needle roller bearings are composed of two main rollers, side rollers and shaft heads installed in two different directions to reduce space and reduce manufacturing costs. Among them, the adjustable combined roller bearing can adjust the position of the core shaft by adjusting the eccentric outer hexagon or the eccentric valve to achieve the purpose of adjusting the axial size of the side roller. Therefore, the two cannot be completely replaced.

The load, speed and working temperature have a wide range of adaptation, and a small amount of changes in working conditions have little tensioner bearing kit effect on the performance of the bearing; Generally, most types of bearings can bear radial and axial loads at the same time, which can simplify the structure. Compared with sliding bearings, needle roller bearings have their own advantages and disadvantages, and each occupies certain applicable occasions
