Product Description
Payment & Delivery


  • Ultra-high precision encoder for closed-loop precise rotation.

  • Suitable for vertically using or upside down using.

  • Easily adjust the clearance by a spanner.

  • Same center of aperture and platform for easy postioning.

  • Shaft system is precisely made by bearing steel, high precision and load capacity.

  • Matched ground worm and gear structure, comfortable movement, small backlash.

  • Clearance elimination structure design for long time working.

  • Laser marking degree scale for reading and positioning.

  • NEMA 17 stepper motor drive and DB9 interface.

  • Hand wheel for manual drive. 




This closed-loop rotary stage includes an encoder for superior position feedback for rotational accuracy. This product provides microradian precision and continuous 360° rotation.


Our motorized rotation stages adopt matched ground worm and gear structure, and the shaft system is precisely made by bearing steel. The motorized rotary stages featured high precision and big load capacity. Specially, the clearance elimination structure is designed for long time working.


This motorized rotation stage has central aperture and zero position. The aperture diameter is 30mm.


It can be connected with our motion controller via DB9 interface and it can be controlled by our computer software via Ethernet interface on controller.

There's a hall effect sensor (as the zero position) built in the rotation stage, so the rotation stage can't move at negative direction to pass over the zero position.
