Needle bearings are roller bearings with cylindrical rollers that are thin and long relative to their diameter. Such rollers are called needle rollers. Despite having a small cross-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 length of the roller), so The radial structure is compact, and its inner diameter size and load capacity are the same as other types of bearings, and its outer diameter is the smallest, especially suitable for support structures with limited radial installation dimensions.Depending on the application occasion, a bearing without an inner ring or a needle roller and cage assembly can be selected. At this time, the journal surface and the housing hole surface matched with the bearing are directly used as the inner and outer rolling surfaces of the bearing. In order to ensure the load capacity and running performance As with bearings with rings, 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 kind of bearing can only bear radial loadIn addition to those listed in the catalog, bearings that can be used for general engineering, such as open-type drawn cup needle roller bearings (1), closed-type drawn cup needle roller bearings(2), needle roller bearing with inner ring(3) and needle roller bearings without inner ring/needle roller bearings without inner ring and without a cage(4), with cage and without cage filled with needle roller bearingsA combined needle roller bearing is a bearing unit composed of radial needle roller bearing and thrust bearing components. It has a compact structure, small size, high rotation accuracy, and can withstand a certain axial load while bearing a high radial load. And the product structure is diverse, widely adaptable, and easy to install. Combined needle roller bearings are widely used in various mechanical equipment such as machine tools, metallurgical machinery, textile machinery, and printing machinery, and can make the mechanical system design very compact and smartThrust bearings consist of thrust cage assemblies with needle rollers or cylindrical rollers or balls and thrust washers. Needle rollers and cylindrical rollers are held and guided by thrust cages. When used with different series of DF thrust bearing washers, many different combinations are available for bearing configurations. Due to the selection of high-precision cylindrical rollers (needle rollers) to increase the contact length, this bearing can obtain high load capacity and high rigidity in a small space. Another advantage is that if the surface of the adjacent part is suitable for the raceway surface, the gasket can be omitted, which can make the design compact. The cylindrical surfaces of the needle rollers and cylindrical rollers used in DF thrust needle roller bearings and thrust cylindrical roller bearings are Modified face to reduce edge stress and increase service life
