8” Rotary Positioning Tables
Key Features
- Precision manufacturing in USA
- High accuracy and repeatability
- Lightweight, cost effective, aluminum construction
- 8” outside diameter for high rigidity
- The use of one single thin section, large diameter, preloaded roller bearing creates:
- Significant increase in rigidity, stability and stiffness
- Super low profile -- a striking 0.713’’ (VR-3153 model) -- considering the 8” diameter
- Reduced weight, inertia and cost
- Large open frame - 5.50” aperture
- Large penetrating angle - 172° (VR-3153 model)
- Worm gear drive
- Two preloaded ball bearings eliminates play on the worm shaft
- NEMA 17 flange
- Automatic and manual operation
- Motors and single axis intelligent servo controllers are available options
