220x310x225mm 313894 Fast delivery Four row bearing 514461 Cylindrical Roller bearing 313894 BSSD

Four-row cylindrical roller bearings mainly bear the combined radial and axial loads mainly in the radial direction. The bearing capacity depends on the raceway angle of the outer ring, and the larger the angle, the greater the bearing capacity. This type of bearing is a separable bearing, which is divided into single-row, double-row and four-row tapered roller bearings according to the number of rows of rolling elements in the bearing.

Cylindrical Roller Bearings Features:

1.High radial loads

2.low friction

3.high strength

4.high speed rotation. 

Four-row cylindrical roller bearings are used almost exclusively in the roll necks of rolling mill stands, calenders and roller presses. Since these bearings are usually mounted on the roll neck with an interference fit, four row cylindrical roller bearings are particularly suitable for rolling mill applications with high rolling speeds.

The cylindrical roller bearings provided by our company have three types: single row (NU, N, NF, NJ, NUP), double row (NN, NNU type), four row (FC, FCD, FCDP, SFC)
