Product details：

Since the rolling elements in cylindrical roller bearings make line contact with raceways,these bearings can accommodate heavy radial loads . The rollers are guided by ribs on either the inner or outer ring ,therefore these bearings aer also suitablefor high speed applications.Furthermore, cylindrical roller bearings are separable ,and relatively easy to install and disassemble even when interference fits are required.
Double and multiple row bearing arrangments are also available.
Single row cylindrical roller bearings can accommodate heavy radial loads and high speeds. They are manufactured in several different designs,the main difference being in the configuration of the flanges .The most popular are the NU,N,NJ and NUP designs.
