NK12/16 Needle Bearing Without The Inner Ring With Good Load Capacity
1. Product Description
NK12/16 Needle Bearing Without The Inner Ring With Good Load Capacity is a cylindrical roller bearing, relative to its diameter, the roller is thin and long.This kind of roller is called a needle roller.Although it has a small section, the bearing still has a high load bearing capacity, so the radial structure is compact, its inner diameter size and load capacity are the same as other types of bearings at the same time, the outer diameter is the smallest, especially suitable for the radial installation size is limited by the support structure.According to the use of different occasions, can be used without inner ring of the bearing or needle roller and cage components & the bearing can only bear radial load. More details pls contact us.

3. Application
NK12/16 Needle Bearing Without The Inner Ring With Good Load Capacity are widely used in textile machine,machine tool ,gearbox etc.
4. Advantages
The needle bearing is a needle roller bearing with thin stamping outer ring.Its main characteristic is the section height is very low and the load bearing capacity is high.It is mainly used for bearings with compact structure, cheap price and the inner hole of bearing box can not be used as raceway of needle cage assembly.Bearings shall be installed in an interference fit manner.If the box shoulder, stop ring and other axial positioning function can be eliminated, then the bearing box hole can be done very simple and economically applicable to the radial installation size is limited by the supporting structure, and the bearing matching journal directly as the rolling surface.As the raceway surface axis, the hardware must be hardened and ground, and only when it is machined to the appropriate size and shape accuracy, the whole set of needle bearings can have a higher life and operating accuracy.At the same time, since there is no inner ring, the diameter of the shaft can also be appropriately increased, thereby increasing the rigidity.
