ASRT 机械轴承精密直驱转台 | ASRT Mechanical-Bearing Direct-Drive Rotary Stage | ASRT 防灰尘防水密封转台

ASRT密封转台可在灰尘或液体存在的恶劣环境中提供精确的角度定位。该转台可以在有灰尘或流体射流的环境中运行。该ASRT也可以在存在切削液的地方使用。应用范围从工业加工自动化到在恶劣环境中的高精度传感器定位。该ASRT转台有效用于产品环境试验和一系列跟踪应用，提供精确的旋转运动。


ASRT系列转台现有三种不同的尺寸，可匹配各种负载和电机额定扭矩。所有尺寸的轴孔选项允许电动，气动和流体馈通。提供高精度光学（增量或绝对）非接触式编码器或坚固的磁性非接触式编码器，上述ASRT转台有许多反馈选项，以满足对于许多苛刻应用的具体要求。


ASRT标准工作温度为0至70℃。冰点以下工作需要选配空气吹扫和干燥剂。空气吹扫平台可以在-20℃至70℃温度范围内工作。


外壳和硬涂层台面上的基于聚合物的涂料提供标准的腐蚀防护。该平台可选棕褐色，黑色和白色涂料颜色。


可以提供100至200rpm的转速。该ASRT包括电气接地轴和外壳，以防止电击和消除RF再辐射，并且包括外壳接地点。标准的圆形密封连接器，而选项包括干燥剂筒，空气吹扫选项和安装法兰配件。
