Nki Style Standard Needle Roller Bearing With Inner Ring Factory

The NKI series needle roller bearings consist of machined bearing rings and needle roller and cage assemblies with cages made from either plastic or deep drawn steel strip. They have an inner ring while series NK is supplied without an inner ring. The bearings without an inner ring are most suitable if the shaft can be hardened and ground, which depends on the application.

In contrast to the outer cups of drawn cup needle roller bearings, which are produced by forming methods, the bearing rings are machined. Due to their non-locating bearing function, the bearings cannot guide the shaft axially in any direction.

Since the inner ring has no flange, it can be installed in the inner ring, outer ring, full set of needle and cage respectively, without limiting the axial displacement of the shaft or the shell. Because of the use of cage to separate the needle roller and reduce friction, it can be used in components with high speed.

In addition, the standard cages for NKI series needle roller bearing are made from sheet steel or plastic (polyamide PA66). Bearings with a plastic cage have the suffix TV.

Application

The needle roller bearings are widely used in the steering transmissions, drivetrain components, sport vehicles, mechanical pumps, industrial machinery etc.
