Product Description Details of XM Series Aluminum Alloy Three-Position Pneumatic Actuators:Structural DesignAdopts a double-piston rack-and-pinion structure, which can achieve a large torque output while maintaining a relatively small volume. The three-position type realizes the control of the intermediate position through a specific mechanical device, such as mechanical braking generated by the movement of two auxiliary pistons. It can provide operating modes like 0°-45°-90° or 0°-90°-180°, and has a stroke fine-tuning capability within ±5° at the 90° position, with the ability to lock at any position. Material SelectionCylinder Block: Made of high-quality aluminum alloy through extrusion forming, with the surface undergoing hard anodizing treatment or Teflon coating, featuring light weight and corrosion resistance.End Covers: Aluminum alloy die-cast, with the surface treated by anodic hardening or metal polyester coating.Pistons: Made of cast aluminum with hard anodizing treatment.Output Shaft: Integrally forged output shaft made of nickel-plated alloy steel, conforming to NAMUR, ISO5211, and DIN3337 standards.Fasteners: All fasteners are made of stainless steel.Basic ParametersAir Supply Pressure: The maximum rated air supply pressure is 8bar, the minimum air supply pressure is 2.5bar. Both double-acting and single-acting pneumatic actuators can work within the pressure range of 2.5-8bar.Operating Temperature: The standard type uses nitrile rubber seals, suitable for temperatures ranging from -20oC to +80oC; the low-temperature type can adopt special seals, applicable to temperatures from -40oC to +80oC; the high-temperature type uses special seals according to customer requirements, with an applicable temperature range up to -15oC to +120oC.Torque Range: The torque range varies with different models. For example, the torque of XM-AT40 is 140 Nm, and the overall series torque range may be between 5 Nm and 12,992 Nm.Connection StandardsThe size of the top mounting hole conforms to VDI/VDE3845 NAMUR standards, facilitating the installation of accessories such as solenoid valves; the size of the bottom mounting hole complies with ISO5211 and DIN3337 standards, making it easy to install with valves. Performance FeaturesLow Friction Coefficient: The inner surface of the cylinder is precision-ground and finished, with advanced anti-corrosion technology applied both internally and externally, resulting in a low friction coefficient of the cylinder and a long service life.Stable and Reliable Operation: Due to the precision rack-and-pinion structure, the actuator operates with small clearance, high efficiency, low noise, stable and reliable action, and is safe and explosion-proof.High Protection Level: The aluminum alloy shell is phosphated, with O-rings at static fit positions and skeleton oil seals at dynamic fit positions, enabling the actuator to reach an IP68 protection level.
