The URS50BPPV6 Vacuum Compatible Rotation Stage provides precision 360° continuous motion in a low profile package. This version can be controlled with the motor mounted encoder and also in open loop. The stepper motor is directly attached to the worm screw using a proprietary bellows coupling that has a high torsional stiffness and is capable of rotation speeds up to 4°/s. All URS rotation stages feature a proprietary 4-point contact ball bearing. The unique, 2-piece design of the URS provides a low-profile compact stage with exceptional stiffness, high reliability and outstanding wobble and eccentricity. The tilted worm screw arrangement allows for 4 symmetric mounting holes, compared to other designs that only feature 2 or 3 mounting holes. This enables the URS stages to provide better support of higher or off-centered loads. Additionally, the flexible preloading system for the worm gear guarantees a backlash-free operation with an MTBF of 20,000 hours.

Note that the cable supplied with the stage is not vacuum compatible.
Can be ordered with a vacuum compatible 25pin SubD connector.

URS50BPPV6真空兼容阶段提供精密360°旋转连续动作在低调包中。这个版本可以控制与电机安装编码器，也在开环。步进电机直接连接到蜗杆螺钉使用专有的波纹管联轴器扭转刚度高,能够加速旋转4°/ s。所有URS旋转阶段均采用专有的4点接触滚珠轴承。独特的，2件式的URS设计提供了一个低轮廓紧凑的阶段，具有卓越的刚度，高可靠性和突出的摆动和偏心。倾斜的蜗杆结构允许有4个对称的安装孔，而其他设计只有2或3个安装孔。这使URS阶段更好地支持较高或偏心载荷。另外，蜗轮蜗杆的柔性预压系统保证了在20,000小时的MTBF下无返料运行。

注意，与舞台一起提供的电缆不是真空兼容的。

可以订购与真空兼容的25pin SubD连接器。
