德国KSB凯士比ACTAIR C4 F05-F07 DD11双作用执行器安装、连接尺寸根据国际标准ISO5211、DIN3337和VDI/VDE3845进行设计。铝制缸体、活塞及端盖，与同规格结构的执行器相比重量*轻。缸体为挤压铝合金，并经硬质阳极氧化处理，内表面质地坚硬，强度，硬度高。采用低摩擦材料制成的滑动轴承，避免了金属间的相互直接接触，摩擦系数低，转动灵活，使用寿命长。

Germany KSB KSAIR ACTAIR C4 F05-F07 DD11 double acting actuator installation, connection size according to international standards ISO5211, DIN3337 and VDI/VDE3845 design. Aluminum cylinders, pistons and end caps are the lightest weights compared to actuators of the same size. The cylinder is extruded aluminum alloy and hard anodized. The inner surface is hard, strong and hard. The sliding bearing made of low-friction material avoids direct contact between the ls, has low friction coefficient, flexible rotation and long service life.
