The MCR 72 has a ball-bearing motor, providing measurements typically in a rotational mode. It also provides measurements in the oscillatory mode for special applications. The MCR 92 is equipped with ...

The difference here is that rather than low-friction sapphire bearings ... be the drag caused by air in the bell jar. [lasersaber]’s current measurements of the motor running at slow speed ...

It was designed to provide ultra smooth motion, the air bearing slideways utilize linear motor technology with ultramarine pitch linear glass scales for position feedback. The air bearing slides ...
