The skew of the rollers determines their effect on the kiln’s axial migration. They do nothing when we locate the rollers parallel to the tyre. We call this situation neutral and use it primarily for the middle pier, while using the remaining rollers as thrust to push the kiln up together with the real thrust roller.

A system and method for reducing roller skew, which involve ascertaining first and second thrust load properties applied to a roller while a rotary body rotates in opposing rotational directions, and adjusting an orientation of at least one bearing assembly for the roller until an amplitude difference between the first and second thrust load properties is below a predetermined threshold.
