Cylindrical Roller Bearing(RNU, RN, NJ, NF, NUP, N) FBX-Rollers of cylindrical roller bearing is guided by the rim on outer or inner ring. Roller and raceway are connected in line, so its radical load rating capacity is quited big, and it is also suitable for high speed rotation. There are many types for cylindrical roller bearing, if divided by structure, there are types of N, NF, NJ, NU, NCL, RN and RNU. If divided by loading capacity, there are standard type and strengthened type cylindrical roller bearings. The external dimension of strengthened cylindrical roller bearing is the same as standard type, diameter, length and number of the roller are increased, so it ahs bigger capacity of load rating. If divided by the rows of the cylindrical rollers, there are single row and multi-row cylindrical roller bearing. All of the FBX cylindrical roller bearings listed in this catalogue are single row. FBX can also provide multi-row cylindrical roller bearings. The radial clearance of FBX cylindrical roller bearings is in accordance with the national standard GB/T4604. Clearance of the cylindrical roller bearing listed in the form is normally the standard clearance, the group C2, C3, and C4 clearance can also be provided.
