Today I would like to introduce you to a practical bearing - RNA type needle roller bearing without inner ring.
Needle roller bearings without inner rings RNA4906, NA type bearings without inner rings are RNA type needle roller bearings. This type of bearing has great limitations in terms of radial mounting dimensions, but it has an extremely high load carrying capacity and a long service life. Since the journal that matches the bearing directly serves as a rolling surface, the shaft must be hardened and ground to the appropriate dimensional and shape accuracy for the complete set of needle roller bearings to have a high life and running accuracy.
Needle roller bearings without inner ring not only have the characteristics of high precision and high rigidity, but also have a long service life and can withstand large loads. It has a very wide range of applications and can be used in machine tools, automobiles, railway vehicles, aerospace and other fields. Compared with other types of bearings, needle roller bearings without inner ring have a higher load capacity and longer service life, so they are widely used in many high-precision and high-load machinery.
In general, the needle roller bearing RNA4906 without inner ring is a very excellent bearing, and its high precision, high rigidity and long life make it have a wide range of application prospects in many fields.
