In the metallurgical industry, rolling mill bearings are essential and important components. Rolling mill bearings mainly include: four-row cylindrical roller bearings, four-row tapered roller bearings, double-row tapered roller bearings, spherical roller bearings, deep groove ball bearings, etc. Today we mainly discuss the four-row cylindrical roller bearing, which is widely used in the metallurgical industry.

First of all, let's understand the characteristics and structure of four-row cylindrical roller bearings:

The main features of four-row cylindrical roller bearings:
The bearing has a large rated dynamic load value in a limited installation space, and can be used for high-speed and high-precision rolling; at the same time, the bearing allows a relatively precise limit tolerance; the inner ring can be combined with the outer components (outer ring, complete set roller) interchangeable assembly, which is conducive to quick roll change.

Structure of four-row cylindrical roller bearings: There are several structures, but the most common are the following three:
FC type: two outer rings with ribs, integral inner ring and comb cage; FCD type: two outer rings with ribs, two inner rings and comb cage; FCDP type: two without outer ring. The outer ring of the rib, two inner rings, two outer retaining rings, one middle retaining ring, hollow rollers, and pin-type cage.

Knowing the structure and characteristics of the bearing will help us to choose a four-row cylindrical roller bearing. If you still have questions about the selection of rolling mill bearings, please consult us FV bearing, ​​a professional rolling mill bearing supplier in China.
