HK Series drawn cup needle roller bearing with open ends
The basic structure consists of a drawn cup, a set of needle rollers or needle rollers and cage assembly. This structure occupies less radial space and has a larger radial load capacity, making it suitable for situations where radial installation space is limited and housing bore is not suitable as raceway. The bearing does not need further axial positioning after being pressed into the housing bore, saving installation and adjustment time and workload. This type of needle roller bearing usually does not require an inner ring. If an inner ring is needed, it can be selected from the product lis

AXK/NTA/AX/AXW Series thrust needle roller and cage assembly
Thrust needle roller bearings are separable bearings (except in special cases), occupying little axial space and easy to install and disassemble. They are suitable for locations where axial position is restricted but must withstand axial loads. This type of thrust needle roller bearing includes structures with two washers and needle roller and cage assembly, a single washer and needle roller and cage assembly, needle roller and cage assembly without washers. Different structures are selected for different applications, and the washers should be fully supported during installation and use.

AS/LS/TRA Series thrust bearing washer
Thrust bearing washers mainly include AS, WS, GS, and LS types. AS thrust washers are typically stamped from high-quality spring steel strip (plate), with thicknesses of 0.8mm and 1mm. They are mainly used in applications where adjacent parts cannot be hardened but require sufficient rigidity and geometric accuracy. The shaft washer (WS), seat washer (GS), and bearing washer (LS) are solid washers made from hardened bearing steel and are typically used in conjunction with thrust cylindrical roller and cage assemblies.

NA/NAV Series machined needle roller bearing with inner ring
Machined needle roller bearings are particularly suitable for applications where radial installation space is limited due to their small radial cross-sectional size, good bearing rigidity, and high radial load carrying capacity. Needle roller bearings can only withstand pure radial loads and cannot limit the axial displacement between the shaft and the housing. During bearing installation, the outer ring axis and the inner ring axis must not be tilted.

K Series radial needle roller and cage assembly
This assembly is suitable for applications where the shaft and housing bore can serve as raceways. The raceways of the shaft and housing bore are machined to the specified dimensional accuracy, geometric accuracy and hardness, ensuring high rotational accuracy. The radial needle roller and cage assembly is a special rolling element assembly in which the needle roller is guided by the cage. This assembly occupies minimal radial space and carries high radial loads, making it the optimal choice for applications where radial space is limited.
