It provides a linear pneumatic stroke while maintaining precise, anti-rotation guidance for the moving carriage. This makes it suitable where side loads or torque could cause a standard cylinder rod to bind or twist.
The stroke range for this guided cylinder family is 20 mm to 400 mm, depending on the specific variant selected.
The piston diameter is 25 mm. Bore size influences achievable force at a given pressure, air consumption, and overall actuator sizing.
It is a double-acting pneumatic actuator, meaning air pressure is used for both extending and retracting motion.
The operating pressure range is 0.15 MPa to 1 MPa (1.5 bar to 10 bar).
The pneumatic connection is G1/8. This helps when selecting fittings, tubing, and valve manifolds.
The guided cylinder family includes versions with plain (sliding) guidance and versions with ball bearing recirculation guidance. The choice typically depends on load, smoothness requirements, and expected duty.
The family supports elastic end stops/plates on both sides, adjustable pneumatic cushioning on both sides, and a shock absorber option with a soft characteristic curve, depending on configuration.
Yes. The mounting position is specified as indifferent, so it can be installed in any orientation as required by the machine design.
Yes. It is designed for position detection using proximity sensors (for end position or intermediate detection, depending on the sensor arrangement and stroke).
The specified working medium is compressed air to ISO 8573-1:2010 class [7:4:4]. Matching air quality helps maintain consistent performance and service life.
Yes, lubricated operation is permitted. If lubricated air is used, it should be continued consistently thereafter to avoid changes in sealing conditions.
The ambient temperature range is -20 °C to +120 °C. For Ex-marked use, the specified ambient range is -20 °C to +70 °C.
The series includes Ex-marking information: ATEX gas category II 2G with protection type Ex h IIC T4 Gb, suitable for Zone 1 and Zone 2 applications when installed and used according to the relevant requirements.
At 6 bar, the theoretical force is 295 N on advance and 247 N on return (values stated for this 25 mm bore guided cylinder family).
Key materials include a wrought aluminium alloy housing and cover, NBR seals, and a high-alloy stainless steel piston rod.
Yes. The material note states RoHS conformity, and PWIS conformity is listed as VDMA24364-B1/B2-L.
The specified impact energy at end positions is 0.15 J to 0.3 J, which can help guide selection of cushioning and any external deceleration measures.
