Parallelism of the air bearing face and its mating surface is optimal when using these stainless steel ball stems. The fine pitch threaded shaft assembled to the stage or system assembly allows for minute adjustments to the preload of the bearing. For convenience, adjustments can be made from either the hex socket at the end of stem or through the cross hole near air bearing.
