Cylindrial Roller Bearings NU200 Series

Cylindrial Roller Bearings NU200 Series are characterized by high radial-, and thrust-load capacities. Cylindrial Roller Bearings NU200 Series probably have the simplest construction in the roller bearings category. These bearings are suitable for carrying relatively higher loads, at high-speed applications.RBEC ratings describe the accuracy and tolerance range of different types of bearings. As a rule, the higher the RBEC number, the tighter the bearing tolerances. Typically,Single Row Cylindrial Bearings NU200 Series are lubricated with oil, which also serves as a coolant.

Precision Roller Bearings NU200 Series are made of alloy or low-carbon steels. Some applications require the use of case-hardened or through-hardened, high-carbon, bearing-quality steel. High-carbon grades of steel do not require carburizing and can be case-hardened by induction heating or through-hardened by conventional heating methods. When low-carbon, carburized grades of steel are used, carbon is introduced after the Cylindrical Roller Bearings are machined to a depth sufficient to produce a hardened case that can sustain bearing loads. The addition of carbon and alloys ensures the proper combination of a hard, fatigue-resistant case and a tough, ductile core.
