Solid Ferrule Needle Roller Bearing
Solid ring needle roller bearings are composed of one or two rings and a needle roller set with a cage. It has a smaller volume and a higher load carrying capacity. Therefore, this bearing can meet the requirements of light weight, small space occupation and large power transmission. Depending on the application, bearings with or without an inner ring can be used.
The outer ring double guard (or double lock ring) with cage needle roller bearing NA, NKI type, can be installed respectively inner ring and outer ring (with lock ring, a full set of needle roller and cage), high speed, divided into single and double row two. Such needle roller bearings with inner rings may be used if the shaft cannot be used as a raceway, i.e. if grinding the shaft to harden it is not possible or economical.

1. Body ring needle roller bearings without inner ring cage needle roller bearings
NA, NKI type bearings without inner ring is RNA, NK type needle roller bearings This bearing has no inner ring, suitable for radial mounting size limited support structure, and the matching bearing journal is directly used as the rolling surface. As the shaft of the raceway surface, the hardware must be quenched and ground, and only when it is machined to the appropriate size and shape accuracy, the whole set of needle roller bearings can have a higher life and operating accuracy. At the same time, because there is no inner ring, the diameter of the shaft can also be appropriately increased, which also increases the rigidity.
2. Solid ring needle roller bearing belt or sealed needle roller bearing without inner ring
Single-sided or double-sided sealing needle roller bearings can effectively prevent the intrusion of dirt, bearing has been filled with an appropriate amount of lithium grease. The inner ring of this type of bearing is wider than the outer ring, which enables the bearing to ensure a good seal and avoid bearing contamination when the shaft has a slight displacement from the bearing box. There is also a lubricating oil hole in the bearing, which can be supplemented by the outer or inner ring according to the needs of the matching. external environment.
