Abstract
A high performance rotary axis. An upper and lower unit are coupled together by a pair of bearings to permit relative rotation between the units. The bearings are biased relative to others along a link to reduce play between the bearings. A processor and sensor provide for detection of relative positions between the units. A floating stop may be provided to permit rotation about the axis in greater than 360°.
