Available in four different stages, the UBR-AIR family of high precision air bearing rotation stages features a diameter that range from 100 mm to 270 mm, a profile height of only 55 mm and a load capacity of up to 40 kg. The UBR-AIR bearing stages are driven by a direct-drive torque motor and fitted with a reference class optical direct-metrology scale encoder. In addition, they also achieve angular resolution down to 0.00002 degrees, repeatability of 0.00003 degrees and a maximum velocity of 360 degrees per second.
