Four-row tapered roller Bearing M268749DW-710-710CD for Rolling Mill Stand

Jul 27, 2021

On April 20, 2021, a batch of four-row tapered roller bearings M268749DW-710-710CD was sent to the UK by sea.

This four-row tapered roller bearing is used on vertical roll. When rolling a slab, the horizontal roll controls the thickness of the slab, and the vertical roll controls the width of the slab. To control the width, a vertical roll is required on the left and right of the roll. Two sets of bearings are used on one vertical roll, so one set of vertical rolls requires 4 sets of the four-row tapered roller bearing.

Below are the basic dimension of the bearing:
