TBG series motorized goniometers
Zolix’s TBG series motorized goniometers are designed for the applications in which small size and high operation rate are needed.
Hard black anodic-oxidation aluminum-alloy are employed as main body materials to present good wear-resistance and excellent appearance.
It is arc V-shaped ball guides that provide higher strength, higher load capability and longer-term durability.
Worm, tin-bronze-made worm gear and standard two-phase stepping motors are used in driving mechanism to offer higher resolution and positioning accuracy.
This series of rotation stages are suitable for being integrated in automation equipment and instruments in which there are strict requirements of space, dimension and weight.
Another suitable application scenario is industrial production lines on which limited motion space and high repetition rate are present.
Features
- Fine grinding worm/worm gear is used in driving mechanism. Tin-bronze-made worm gears present longer-term durability
- Smooth running is benefit from employed arc V-shaped ball guide
