4. The bearing bears directly on the concrete substructure. 5. Lateral forces on expansion bearings are restrained by means of friction, keeper angles, or concrete keeper blocks (keys). Lateral forces on fixed bearings are restrained by anchor rods. Some states prefer to attach the bearings to the beam by welding and others prefer bolting.

The lower bearing of the spindle rested on a beam that the miller could raise or lower to adjust the cut of his stones minutely, according to information gathered by his celebrated miller's thumb ("rule of thumb") when he felt the texture of the meal.

This is primarily due to the support bearing design and the mill drive used. The mill is shell-supported, mounted on slide shoe bearings at both ends and made completely as a welded design. The mill with the compact drive version features an INTEGRAL DRIVE, whose planetary gear is mounted to the mill flange.
