[RimstarOrg] has brought us an oldie but goodie this week. He’s built a ball bearing motor, a design which has been causing engineers and scientists to squabble for decades. [RimstarOrg] used a ...

ABTech overcame numerous challenges in designing a highspeed rail inspection spindle, using cutting-edge air bearing tech to ...

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 ...

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 UPR-270 Air features best value for wobble and flatness and one can reach high accuracy because of high-precision air bearing. All rotation stages UPR-270 AIR are directly driven by a torque motor ...
