Four-row cylindrical roller bearing for mill


Code	Model	d	D	B	r	L	kg	Cr	Cor	rpm

As one of main roll bearings,four-row cylindrical roller bearing has compact structure,high stiffness and high radial load capacity .But it can not hold axial load.Because inner ring has no rib,inner ring and outer ring can be mounted separately(with all rollers and cages).It is convient to clean ,check and dismount the bearings.

Four-row cylindrical roller bearings are suitable for high speed and high precision roll,such as wire rod mill,section mill,cold/hot strip mill and blooming mill,etc.

Four-row cylindrical roller bearings often adopt brass cage or pin-type cage.
