结构特征

structure  character

双活塞推动，齿条齿轮传动，结构紧凑，装配位置对称，动作迅速，通过简单的活塞颠倒可以改变输出轴转向。角行程输出：0°-90°。

Dual-piston driven.toothed bar and gear driven,structure is compact，position of assembly is symmetrical. Motion is swift.turning of output axis can be changed through simple reversal of piston.Output of angle travel:0°-90°.

气缸体body

挤压铝合金缸体或铸钢。表面进行阳极氧化处理，大大提高了硬度和耐腐蚀性。气缸内表面经精细珩磨加工，摩擦系数低，使用寿命长。

Extruded aluminum alloy cylinder body or cast steel,The surface is treated by anticathode oxidation which greatly improves the rigidity and anti-corrosion.The intenal surface of cylinder is honed and processed so that the friction coefficient is low and  the service life is long.
