Needle bearing

Needle roller bearings are equipped with thin and long rollers (the length of the rollers is 3 to 10 times the diameter, and the diameter is generally not more than 5mm), so the radial structure is compact. When the inner diameter size and load capacity are the same as other types of bearings, the outer The smallest diameter is especially suitable for the support structure with limited radial installation size. Needle roller bearings can choose bearings without inner rings or needle roller and cage assemblies according to different application occasions. At this time, the journal surface and shell matching the bearing The surface of the hole is directly used as the inner and outer rolling surfaces of the bearing. In order to ensure the same load capacity and running performance as the 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. The needle bearing is a bearing unit composed of a radial needle roller bearing and a thrust bearing. It has a compact structure, small size, high rotation accuracy, and can bear 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 smart.
