Parker rotary stages are designed to produce precision rotary motion. The basic components in these stages are a base, precision bearing, drive mechanism and top (load platform). The base of all the units house the main bearing and drive mechanism and is designed to be mounted to a stationary surface. The main bearings provide low friction contact between the base and top. The drive mechanism used is a tangent arm and the table top provides a mounting surface for mounting payloads. The tangent arm drive mechanism produces a very fine resolution over a limited rotary travel range. Angular rotation is controlled by three control knobs. The release knob disengages the shaft from the drive, freeing the table to be rotated by hand to a desired location. The release knob is then tightened to re-engage the drive mechanism and transfer control to the adjustment knob which, when rotated, produces precise angular positioning of the shaft and table top. The locking knob can then be used to positively lock the table at the desired setting.

The 2500-series rotary stages offer low friction rotary positioning, precise angular adjustment at any position and position locking.
