The Introduction Of Needle Roller Bearing

- Jun 11, 2018 -

The introduction of needle roller bearing

Folding needle bearing with fine needle bearing with long roller (roller length is 3 ~ 10 times the diameter, diameter is generally not more than 5 mm), so the radial structure is compact, its diameter and load capacity at the same time, with other types of bearing outside diameter to a minimum, especially suitable for the limited size of the radial installation support structure. 

Needle roller bearing according to the use of different occasions, can be used without inner ring of the bearing or needle roller and cage components, at this time to suit the bearing surface of the shaft neck and the shell hole directly as a bearing surfaceOutside the rolling surface, in order to ensure the load capacity and operating performance and you have the same ring bearing, axis or shell hole hardness on the surface of the raceway, the machining accuracy and surface quality and bearing ring.

needle roller bearing

Use combination of needle roller bearing is a centripetal needle bearing and thrust bearing components of bearing unit, the compact structure small volume, rotation of high precision, high in can bear radial load at the same time absorb a certain amount of axial load forms wide adaptability is easy to install and product structure combined needle roller bearing is widely used in machine tools, metallurgy machinery textile machinery, printing machinery and other machinery and equipment, and can make the mechanical system design is very compact and nimble.
