Four-row cylindrical roller bearing BC4B 457628 (200x285x200mm) is a very popular bearing for high-speed long rolling mill. Its outer ring assembly RBC4B 457628 and inner sleeve LBC4B 457628 (Bushing) are interchangeable parts. FV is a well-known manufacturer of rolling mill bearings.


Longest possible service life.  For really long products. 

Contamination, extremely high loads, varying speeds and reversing torques push equipment in rod, bar, wire and section mills to the limit and sometimes beyond, with unplanned maintenance downtime cutting into the mill's profits.


If a bearing fails, all production must be stopped causing costly, unplanned downtime. At the same time, there is constant pressure to optimize production and cut costs.

The FV four-row cylindrical roller bearing is a new reliable bearing design, replacing the previous old designs. All needed advanced technical features have been maximized and put in place to achieve the longest possible service life by performance and robustness.

The bearing also has features for more reliable mounting, resulting in lower TCO due to less maintenance needed.


Brass or steel cage.

The new bearing comes with brass cages - optimized for the application - as the standard offer. It can also be offered alternatively with a steel cage


The complete solution or as separate parts.

The FV four-row cylindrical roller bearing range covers all necessary sizes. The whole range can be ordered as complete bearings, but you can also order them as separate parts: inner rings or outer rings together with rollers and cages.

Tolerances and clearances: ISO standard, Perfect interchange
