NT Series
Features
|
|
|
The NT is a precision reducer specifically designed for rotary table applications to provide High Precision with High output speed.
The NT provides significant advantages over traditional rotary table worm gear designs:
- Efficiency = 80%
- Indexing Accuracy = ±2.5 arc-sec. (with external encoder)
- Repeatability = ±1.0 arc-sec. (with external encoder)
- Reduced assembly time:
· No Backlash Adjustment
· No pre-loading
· No Run-out Adjustment
- Low wear due to rolling contact of teeth increases reliability
- High number of teeth continuously engaged provides large shock load capacity
