● 采用国际规范尺寸:输出轴槽、螺孔;顶部安装孔尺寸符合NAMUR标准;气源接口尺寸符合NAMUR标准;底部安装孔尺寸符合IS05211、DIN3337标准，方便安装电磁阀限位开关等附件。
 Design & Constructin of BAILEFU Pneumatic Actuators

气动执行器结构
Construction of Pneumatic Actuator

● Extruded aluminum ASTM6005 body with bath internal and external corrosion protection having honed cylinder surface for longer life and low coefficient of friction.
● Dual piston rack and pinion design for compact construction, symmetric mounting position, high-cycle fife and fast operation, reverse rotation can be accomplished in the field by simply inverting the pistons.
● Multiple bearings and guides on racks and pistons, low friction, high cycle life and prevent shaft blowout.
● Modular preloaded spring cartridge design, with coatedspring for simple versatile range, greater safely and corrosion resistance, longer cycle life.
● Fully machined teeth on piston and pinion for accurate low backlash rack and pinion 　　engagement, maximum efficlency. Stalnless steel fasteners for long term corroslon resistance
● Full conformance to the latest specifications: IS05211,DIN 3337 and Namur or product inter changeahility and easy mounting of solenoids, limit switches and other aocessodes.
