Four row bearing 315513 315257A cylindrical roller bearings BC4-8002/HA6 Rolling mill bearing 315513 BSSD

Four-row cylindrical bearings are almost exclusive to metals industry and carry heavy radial loads in steel, aluminum and other metal rolling mills.

Design offers very high radial load capacity. No thrust capacity.

Straight and tapered bores available.

Inner races are interchangeable with outer assemblies.

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.
