The AirTAC AirTAC SAI200X70 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 70mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAI200X70 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty linear motion. Delivering a substantial 15708 N push force at 0.5 MPa, this 200 mm bore actuator is built to move massive loads. The 70 mm stroke provides a compact extension for high-force, short-travel operations.
This model features a SUS420J2 stainless steel piston rod for superior corrosion resistance and structural integrity. It utilizes PT tapered port threads for a reliable, high-pressure pneumatic seal. For applications requiring drop-down safety or intermediate load holding, the related SAIL variant with an air-released lock is recommended.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Provides the intense 15708 N push force required to seat heavy metal components in stamping and forming dies.
Short 70 mm stroke delivers rapid, high-torque actuation for opening and closing large industrial process valves.
Generates massive holding pressure to secure large workpieces firmly in place during heavy hydraulic press operations.
Selecting the SAI200X70 is optimal when an application demands extreme thrust within a short stroke envelope, as stepping down to a 160 mm bore reduces the 0.5 MPa push force to 10053 N. Being a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 cylinders by matching the 200 mm bore, 70 mm stroke, G3/4 port, and standard mounting accessories.
Because the 70 mm stroke is relatively short, rod-bearing bending is minimal, but ensure your mounting accessory (such as a TC trunnion or CA clevis) can withstand the high torque generated by this 15708 N force. Note that the standard adjustable air cushions only decelerate the piston at stroke end; they do not hold a load if air pressure is lost.
Quick checklist
The SAI200X70 cylinder provides a push force of 15708 N and a pull force of 15080 N at 0.5 MPa. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X70 is a genuine ISO 15552 profile cylinder. It is dimensionally interchangeable with other ISO 15552 cylinders matching the 200 mm bore, 70 mm stroke, and G3/4 port specifications.
