Roll neck requirements

 In most rolling mill applications fourrow taper roller bearings are mounted

with a loose fit on the roll neck. The roll neck journal and the axial abutment
for the inner rings must have a certain minimum hardness. The recommended
hardness is • 45 Shore (≈ 34 HRC) for the roll neck surface and • 60 Shore (≈ 45 HRC) for the axial abutments for the inner rings
