Hcsz HK1412 NTN THK NSK Needle Roller Bearing Correction Equipment Bearing

Needle roller bearing is a roller bearing with cylindrical rollers. The rollers are thin and long relative to their diameters. This kind of roller is called needle roller. Although it has a small section, the bearing still has a high load bearing capacity. Needle roller bearings are equipped with thin and long rollers (roller diameter D ≤ 5mm, L/D ≥ 2.5, L is the roller length). Therefore, the radial structure is compact. When its inner diameter and load capacity are the same as those of other types of bearings, the outer diameter is the smallest. It is especially suitable for supporting structures with limited radial installation size.

Bearing without inner ring or needle roller and cage assembly can be selected according to different applications. At this time, the journal surface and housing hole surface matched with the bearing are directly used as the inner and outer rolling surfaces of the bearing. To ensure the same load capacity and running performance as the bearing with ring, the hardness, machining accuracy and surface quality of the raceway surface of the shaft or housing hole should be similar to the raceway of the bearing ring. This type of bearing can only bear radial load.

The friction coefficient of rolling bearing is smaller than that of sliding bearing, and the transmission efficiency is high. Generally, the friction coefficient of sliding bearing is 0.08-0.12, while that of rolling bearing is only 0.001-0.005; Rolling bearings have been standardized, serialized and generalized, which are suitable for mass production and supply, and are very convenient for use and maintenance; Rolling bearings are made of bearing steel and heat treated.

Therefore, rolling bearings not only have higher mechanical properties and longer service life, but also can save the expensive non-ferrous metals used to manufacture sliding bearings; The internal clearance of rolling bearing is very small, and the machining accuracy of each part is high, so the running accuracy is high. At the same time, the rigidity of the bearing can be increased by preloading. This is very important for precision machinery; Some rolling bearings can bear radial load and axial load at the same time, so the structure of bearing support can be simplified; As the rolling bearing has high transmission efficiency and less heat, it can reduce the consumption of lubricating oil and save lubrication maintenance; Rolling bearings can be conveniently applied to any axis in space.
