Four row cylindrical roller bearings
<p>Four row cylindrical roller bearings can carry much heavier radial load and shock load. They have higher precision and can be applied in the equipment which runs with high rotational speed. Grinding the surface of raceway and roller at same time after the inner ring is pressed on roller neck, it favors the improvement of rolling precision and the free adjustment of mounting clearance of bearings. These bearings are mostly applied to the working roller and backup roller of rolling mills and some other cases.</p> <p>FC: double outer rings, single inner ring, and inner without flange.</p> <p>FCD: double outer rings, double inner rings, and inner ring without flange.</p> <p>FCDP: double outer rings, only have center flange, but with loose rib, double inner ring, inner without flange.</p>

Double row cylindrical roller bearings
<p>Cylindrical roller bearings without ribs on the inner or outer ring, the inner and outer rings can move relative to the axial direction, so they can be used as free end bearings. Cylindrical roller bearings with double ribs on one side of the inner ring and outer ring and a single rib on the other side of the ring can withstand a certain degree of axial load in one direction. Generally, a steel stamping cage is used, or a copper alloy turning solid cage is used. However, there are also part of the use of polyamide forming cage.</p>

Single row cylindrical roller bearings
<p>Single row cylindrical roller bearings, as free supporting, are usually matched with angular contact ball bearings which serve as fixed supporting. The most commonly used cylindrical roller bearings in the machine tool are double cylindrical roller bearing with tapered bore. This kind of bearing can bear greater radial load with detachable inner and outer rings, and can not bear the axial load , so they are often used with double-direction angular contact thrust ball bearings which bear axial load.</p>

Rolling mill bearings
<p>Cylindrical rollers and raceways are linear contact bearings. Load capacity, mainly bear radial load. The friction between the rolling element and the rib of the ring is small, which is suitable for high-speed rotation. According to whether the ring has ribs or not, it can be divided into single row cylindrical roller bearings such as NU, NJ, NUP, N, NF, and double row cylindrical roller bearings such as NNU and NN. The bearing is a structure in which the inner ring and the outer ring can be separated.</p>
