Introduction:
Needle roller bearings ( needle bearing ) is a cylindrical roller bearing, roller relative to its diameter, thin and long. Needle roller as such. Despite having a smaller cross-section, still has a higher load bearing capacity, therefore, especially suitable for the radial space-constrained occasions.
Characteristics and uses:
Needle roller bearing with thin and long roller ( roller length to diameter of 3 ~ 10 times, the diameter of generally not more than 5mm ), thus radially compact structure, its diameter size and load capacity compared with other types of bearings at the same time, the outer diameter of the smallest, especially suitable for the radial dimension restricted support results.
According to different use occasions, can choose the inner ring bearings or needle roller and cage assemblies, this time with the bearing surface and match the shaft neck housing bore surface directly as a bearing inner, outer rolling surface, to ensure that the load capacity and operating performance and bearing the same with rings, the shaft or housing holes groove surface hardness, processing the precision and surface quality of bearing ring raceway and similar. These bearings can only bear radial load.
Needle bearings have a large surface area that is in contact with the bearing outer surfaces compared to ball bearings. Additionally there is less added clearance (difference between the diameter of the shaft and the diameter of the bearing) so they are much more compact. The typical structure consists of an a needle cage which orients and contains the needle rollers, the needle rollers themselves, and an outer race(sometimes housing itself).
