Type of needle roller bearing

SINO BEARINGSAug 24, 2022
combination
Combined needle roller bearing is a bearing unit composed of centripetal needle roller bearing and thrust bearing parts. It has compact structure, small volume, high rotation accuracy, and can bear a certain axial load while bearing a high radial load. And the product structure of various forms, wide adaptability, 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 is very compact and dexterous.

Thrust type
A thrust bearing consists of a thrust cage assembly with a needle or cylindrical roller or ball bearing and a thrust washer. The needle and cylindrical roller are held and guided by a thrust cage. When used with different series of DF thrust bearing washers, many different combinations of bearing configurations are available. Because THE HIGH PRECISION CYLINDRICAL roller (needle roller) is used to increase the contact length, the bearing can obtain high load capacity and high stiffness in a small space. Another advantage is that if the adjacent parts surface is suitable for raceway surface can be omitted gasket, can make the design compact, DF thrust needle roller bearings and thrust cylindrical roller bearings used needle and cylindrical roller cylindrical surface for the modified surface, can reduce the edge stress, improve the service life.
