Parker: Manual Rotary Positioning Stages 2500/M2500 Series

Daedal precision rotary stages are utilized whenever manually controlled rotation or precise angular positioning are needed. The primary components include: a stationary base; a pre-loaded angular contact main bearing; drive mechanism. and rotating top.

Rotary Positioner Principles

Parker Daedal rotary stages and tables produce controlled rotation and angular positioning

Tangent Arm Drive

With some stages (models 2520, 2525, 4575), the drive mechanism is a tangent arm drive. Angular rotation, with this system, 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.

Precision Worm Gear Drive

A precision worm gear drive is employed as the drive mechanism for the other Parker Daedal stages. A worm wheel (gear), which is attached to the table shaft, meshes with the worm drive, whose shaft extends out of the housing. Controlled rotation of the worm shaft creates precise angular rotation of the worm wheel and table shaft. 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.

Standard Features

Parker Daedal has engineered all of its rotary positioners with emphasis on construction and detail. The resulting stages exhibit outstanding quality and proven, reliable performance. All models are manufactured on the very best automated equipment, skilfully assembled, and thoroughly inspected and tested. This enables units manufactured in production quantities to satisfy critical performance specifications. All Parker Daedal rotary positioning devices feature:

• Aluminium/steel construction

• Protective black anodize finish

• Low-friction rotary adjustment

• Precise/accurate movement

• Trouble-free operation

Series 2500 rotary positioners offer low-friction rotary positioning, quick manual table top rotation, precise angular adjustment at any selected position, and positive locking. These miniature units have a preloaded angular contact ball bearing system which provides smooth, continuous rotary movement.

Models 2525/M2525 and 2535/M2535 include a dial and vernier for direct position readout (readable to six arcminutes). These stages can be mounted in a horizontal or vertical position, and can be combined with compatible linear stages for linear-rotary applications.

Ordering Code: 10000, 20000, 2520, 2525, 2530, 2535, 30000, 4575, M10000, M20000, M2520, M2525, M2530, M2535, M30000, M4575
