Metal Challenge #7: Premature roll neck bearing failures

When you mount traditional roll neck bearings with spacers, there is a risk of mixing components. That might result in the wrong bearing clearance and subsequent failure.

Less risk of faulty assembly with a more straightforward design

Roll neck bearings are commonly large, heavy and rather complex units. Traditionally, they come with spacers, but that introduces a higher risk of mix-ups of components that can result in the wrong bearing clearance.

Clever engineering reduces the risk of failure

The wrong bearing clearance for roll neck bearings can result in premature bearing failure. SKF four-row tapered roller bearings are designed without spacers, reducing the mix-up risk. This enables easier mounting, less chance of mixing components and reduced maintenance cost.

More benefits without spacers

Having no spacers simplifies assembly, but it also gives other benefits. Without spacers, the inner ring width tolerance is reduced, facilitating the axial location of the bearing on the roll neck in a simple way. It is also possible to achieve a more favourable load distribution in the bearing, which extends the bearing service life.
