An advanced version of rolling mill bearing — six-row cylindrical roller bearing

Aug 02, 2021

Four-row cylindrical roller bearings are one of the most commonly used bearings in rolling mill equipment. Today, FV Bearings introduces a new type of six-row cylindrical roller bearings.

The six row cylindrical roller bearing ‘s outer ring is changed from two outer rings to one outer ring, removing the fixed ribs and changing to a movable intermediate ring, so that the six rows of rolling elements use the same raceway, and the outer ring does not need to be grouped in the bearing assembly, and the six rows of raceways  can bear the load at the same time, which improves the service life of the bearing. It also has the following characteristics.

1) The fixed rib is removed, and the outer ring becomes a simple cylindrical shape, so it is easy to forged,

2) The outer groove is changed from plunge grinding to reciprocating grinding, which improves groove roughness, improves the production efficiency, reduces the cost of the bearing, and improves the life of the bearing.

3) All the outer ring adopts live retaining ring, which avoids the inevitable oil groove of the fixed rib, the quenching stress concentration caused by the oil groove, and the ribs are prone to grinding cracks and other quality problems, which improves the effective bearing load. Excellent and reliability
