Cylindrial Roller Bearings NU2200 Series

Features include thrust collars, parallel or tapered bore and lubrication holes and grooves. This type of bearings feature high radial load capacity as the rollers and raceway are in linear contact. Our cylindrical bearings are equally suitable for heavy radial and impact loading.

Cylindrial Roller Bearings NU2200 Series are characterized by high radial-, and moderate thrust-load capacities.  They contain cylindrically-shaped roller, which are nevertheless not true cylinders. Instead, they are crowned or end-relieved to reduce stress concentrations. This particular geometry results in low friction and allows high-speed applications. Single Row Cylindrial Roller Bearings NU2200 are commonly available in precision grades such as RBEC-5, a classification from the Roller Bearing Engineers Committee (RBEC). 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, Cylindrical Roller Bearings are lubricated with oil, which also serves as a coolant.

Precision Roller Bearings NU2200 Series are used in a variety of applications. Examples include mining, petroleum production, power generation, power transmission, cement processing, aggregate crushing, and metal recycling. Some cylindrical roller bearings are used in briquetting machines, rubber mixing equipment, rolling mills, rotary dryers, or pulp and paper machinery. Others are used in construction equipment, crushers, electric motors, blowers and fans, gears and drives, plastics machinery, machine tools and traction motors and pumps.
