Rotary table RTLA-180-300
RTLA Series motorized rotation stages provide precision angular positioning accuracy combined with
high load capacity. All RTLA stages are constructed of anodized aluminum, with rotation accuracy ensured by
the precision bearings and ground worm gear drive system. The single monolithic design offers improved stiffness
without compromising dynamic performance. RTLA stages are driven by the two phase stepper motors
with programmable micro-stepping resolutions to provide sub arc-sec angular positioning.
- Large center aperture 180 mm
- Worm gear drive
- 360 deg rotation
- Stepper or servo motor driven
