Introduction Of Needle Roller Bearings

wallpapers Environment 2020-12-22

Needle roller bearings are equipped with thin and long rollers (the roller length is 3-10 times the diameter, and the diameter is generally not greater than 5mm), so the radial structure is compact, and its inner diameter and load capacity are the same as other types of bearings. The smallest diameter, especially suitable for supporting structures with limited radial installation dimensions.


Needle roller bearings can choose bearings without inner ring or needle roller and cage components according to different applications. At this time, the journal surface and the surface of the housing hole that match the bearing directly serve as the inner and outer rolling surfaces of the bearing to ensure the load capacity The running performance is the same as that of a bearing with a ring. The hardness, machining accuracy and surface quality of the raceway surface of the shaft or housing hole should be the same as that of the bearing ring.


Purpose The combined needle roller bearing is a bearing unit composed of radial needle roller bearings and thrust bearing components. It has a compact structure and small volume, high rotation accuracy, and can bear a certain axial load while bearing a high radial load. And the product structure is diverse, wide adaptable and easy to install.


Combined needle roller bearings are widely used in machine tools, metallurgical machinery, textile machinery and printing machinery and other mechanical equipment, and can make the mechanical system design very compact and smart.
