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 bearing and drive mechanism and is designed to be mounted to a stationary surface. The precision bearings provide low friction contact between the base and top while providing great geometric performance. The drive mechanism used is a worm gear and the table top provides a mounting surface for mounting payloads. The precision worm gear drive mechanism consists of a worm wheel (gear) and worm drive. Controlled rotation of the worm drive shaft creates precise angular rotation of the worm wheel and table top. The worm gear and shaft are matched sets and are preloaded to remove backlash. This type of drive provides high resolution (180:1) and continuous angular positioning over a full 360° range.

The 10000- and 20000-series offer low profile rotary positioning while the 30000-series offers high payload capacity and a large footprint.
