Cylindrical roller bearings mostly consist of the cage, the rollers and guided by two capped edges on a ring. It is a separable bearing, convenient for it's assembly and disassembly especially it has the advantages in a condition that the interference is required and assorted with inner ring, outer ring and housing. The bearing of this type can normally take the radial load, on the other hand, single row cylindrical roller bearing with ribbed inner ring and ribbed outer ring can take smaller axial load or intermittent axial load, this kind of bearing has a larger carrying capacity of axial load compare with the deep-grooves ball bearing. The structure of the bearing showing that it runs very well under high rotational speed.
Cylindrical Roller Bearing
(RNU, RN, NJ, NF, NUP, N)
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 cylindrical roller bearings listed in this catalogue are single row. We can also provide multi-row cylindrical roller bearings.
The radial clearance of 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.
