Drawn cup needle roller bearings

NA, NKI bearings are RNA and NK needle bearings without inner ring.

Such a bearing has no inner ring and is suitable for a support structure in which the radial mounting size is limited, and the journal that matches the bearing directly serves as a rolling surface. As the axis of the raceway surface, the hardware must be hardened and ground, and the entire needle roller bearing can only have a high life and running accuracy when it is machined to the appropriate size and shape accuracy. At the same time, since there is no inner ring, the diameter of the shaft can be appropriately increased, thereby also increasing the rigidity.

Solid ferrule needle bearings consist of one or two ferrules and a needle set with a cage. Depending on the application, it can be divided into bearings with or without inner ring. Therefore, the physical ferrule needle roller bearing can meet the requirements of light weight, small space occupation and large transmission power. Solid ferrule needle bearings have a small volume and high load carrying capacity.

Depending on the application, bearings or needle roller and cage assemblies without inner ring can be used. The journal surface and the housing hole surface that match the bearing directly serve as the inner and outer rolling surfaces of the bearing to ensure load capacity and running performance. As with ferrule bearings, the hardness of the raceway surface of the shaft or housing bore, the machining accuracy and surface quality should be similar to the raceway of the bearing ring.

There are many types of drawn cup needle roller bearings in China, among which the most representative are: closed drawn cup needle roller bearings, inner ring needle roller bearings, and inner ring needle roller bearings, without inner ring without cage needle roller bearings. With cages and cages without needles, SKF can also supply various types of needle bearings. It is believed that the type of needle roller bearings for drawn cups will be contributed by many experts and scholars. More bright.
