Four Row Taper Roller Bearings

1. Due to tapered design, the bearing is able to carry a combination of significant radial & axial loads in particular in Cold Rolling Mills.

2. Depending upon the anticipated application loads, a higher radial capacity series or a higher axial capacity series is chosen. In almost all cases of 4 high or 6 high cold rolling mills, there is no need for an additional axial bearing in the assembly. This will contribute to a cost reduction in the overall assembly of back up rolls.

3. The most important advantage which a 4 Row Taper Roller Bearing has over Spherical roller bearing is that 4 Row taper roller assemblies are used mostly on roll neck application where high radial loads are carried and limited radial space is available.

Four Row Cylindrical Roller Bearings

This Type Of Bearing Is The Most Widely Used Bearings Amongst The Various Rolling Mill Bearings, In Cold Rolling Industry, The Main Characteristics Are:

1. The maximum dynamic load rating can be achieved with a limited mounting space.

2. They are applicable for high speed mills.

3. They permit more accurate limiting tolerances.

4. They can only accommodate radial load and as such for roll neck bearing application in cold rolling mills a thrust bearing is fitted on non driving side of roll neck, to accommodate for thrust loads.

Ball Bearings

The bearings used in multi-roll cold strip rolling mill have a thinner wall
thickness and they are mounted on back roll.
They permit high radial load capacity & dimensional accuracy, however these bearings do not accommodate axial loads.

Sendzimir Mill Bearings

The bearings used in multi-roll cold strip rolling mill have a thinner wall thickness and they are mounted on back roll. They permit high radial load capacity & dimensional accuracy, however these bearings do not accommodate axial loads.

 

Spherical Roller Bearings

These bearings are mainly used in machine assembly, where radial & axial loads are accommodated. However its use is limited to nominal loads & low speeds.
