WN03RA200S Motorized Rotation Stages with Steeper Motor
WN03RA200S motorized rotation stage with steeper motor adopts the high precision crossed-roller bearing, keeping the movement at a proper alignment and parallelism. The motorized rotation stage can be used horizontally as well vertically. It can also be combined with other stages to form multi-dimensional stages.
Center load capacity is 250kg; table size is φ200mm; angle range is 360°.

- Equipped with stepper motor.
- High precision, high load capacity crossed-roller bearing ensures the coaxial movement, keeping the movement at a proper alignment and parallelism.
- High precision worm and gear structure makes it easier to move; the precision rotary stage could rotate forward and backward with minimal backlash.
- The special design could enable the extreme low run-out and eccentricity of the stage, making the rotation more stable.
- The scale along the outer edge of precision stage's platform is a laser marking ruler, making it easier to return to the initial position and read the values.
- Stepper motor and worm gear are combined through high quality elastic coupling, helping eliminate eccentricity disturbance and lower the noise.
- labyrinth structure between rotary table and base could prevent the damage caused by foreign materials falling into crossed-roller bearing or worm gear. Such structure guarantees the long lifespan of rotary table and its accuracy.
- Lubrication structure inside the rotary table allows less abrasion and a longer lifespan.
