Needle roller bearings are a type of roller bearings, although sometimes the size of the rollers slightly exceeds the needle roller size range defined by JIS, but they are still generally called needle roller bearings. Needle roller bearings can be divided into radial bearings and thrust bearings according to the direction of the load. Among them, radial bearings include: various series of stamped outer ring type, solid type, and special-purpose bolt type and ring type roller needle roller bearings. NSK needle roller and cage assembly NSK needle roller and cage assembly is easy to install and use, and the needle rollers will not fall off if they are combined. Although the design space occupied is small, it has a large carrying capacity. Due to the unique structure of the cage, it can accurately guide the needle roller and achieve ideal lubrication, so it can be used at high speed. The needle roller generatrix has convexity, which can alleviate the stress concentration at the end of the needle roller caused by the small installation error and the deformation of the shaft, and prolong the service life of the bearing. NSK drawn cup needle roller bearings NSK drawn cup needle roller bearings (with cage type and full complement needle roller type) have a unique outer ring structure, which is a type of bearing with many special features in rolling bearings. These special features include: outer ring The wall thickness is the thinnest, and the load capacity is large; it is made of strictly selected special alloy steel plate, which has a high ultimate load; the cage has undergone surface hardening treatment, and has strong wear resistance; the limit speed is high, and it is easy to install. NSK Solid Needle Roller Bearings Solid needle roller bearings have high precision, take up little design space, and have strong bearing capacity. Its application is very extensive. The ferrule is made of strictly selected vacuum degassed bearing steel or carburized steel, and after heat treatment, it is finely ground. Inside the outer ring with strong double ribs, there are many high-precision needle rollers with a certain convexity. The cage is lightweight and extremely tough, guiding large diameter needle rollers precisely and smoothly. NSK Thrust Needle Roller Bearings Thrust Needle Roller Bearings are available in Metric and Inch. The cage in the thrust needle roller and cage assembly is interlocked by two and a half pieces of cages, which are precision stamped from steel plates and surface hardened. High-precision needle rollers are assembled into the cage, making it high-strength and wear-resistant. The needle rollers are fully held by the cage, which can withstand large axial loads while rotating smoothly. Moreover, the assembly space is small, and it is easy to replace the original thrust washer (the general name of the shaft ring and the seat ring, the same below). The needle roller and cage assembly is equipped with several thrust washers of different thicknesses, so the thrust washer with the optimum thickness can be selected according to the assembly conditions around the bearing. NSK Bolt Type Roller Needle Roller Bearings Bolt Type Roller Needle Roller Bearings have a thicker outer ring and a convex needle busbar. The raceway surface of the stud bolts has been hardened and has a certain degree of toughness, which can withstand impact loads. NSK retaining ring roller needle roller bearings retaining ring roller needle roller bearings have a thick outer ring, convex needle roller busbars, high load capacity, and can withstand impact loads. This type of bearing is non-separable and easy to use, and is widely used in rollers, cams, rocker arms, etc. NSK drawn cup needle roller clutch bearing has a unique drawn cup structure and is a very compact one-way clutch bearing. It has the characteristics of light weight, small cross-sectional size and large moment capacity. This type of bearing has precise action, small frictional moment when overrunning, and easy installation. In addition, there are FCP/FCU series products applied to plastic bearing housings.
