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 automation. Delivering a substantial 15708 N push force at 0.5 MPa, this 200 mm bore unit is built to move massive loads reliably. The 70 mm stroke provides a short, powerful extension for high-impact operations.
This specific configuration features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in harsh environments. It utilizes PT tapered port threads and lacks a standard magnet. For applications requiring position holding without live air pressure, consider the SAIL variant with an air-released lock.

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 robust 15708 N push force needed for short-stroke stamping and metal bending operations.
Ideal for high-tonnage pressing and riveting tasks where a compact 70 mm stroke delivers massive impact.
Secures large fabricated components securely during machining or welding using immense holding thrust.
Select this 200 mm bore cylinder when 160 mm (10053 N at 0.5 MPa) cannot generate the required thrust. The 70 mm stroke is optimal for short, high-force clamping or pressing tasks. Because the standard SAI lacks a position lock, loads will drift if air pressure is lost.
This model ensures true ISO 15552 mounting interchangeability. To match this replacement exactly, confirm the 200 mm bore, 70 mm stroke, G3/4 PT ports, and your required mounting accessory like the TC trunnion. Note that a magnet (-S) is not included on this unit.
Quick checklist
At 0.5 MPa operating pressure, the SAI200X70 generates a push force of 15708 N and a pull force of 15080 N. It can achieve up to 21991 N push force at 0.7 MPa.
Yes, the SAI200X70 is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders by matching the 200 mm bore, 70 mm stroke, and mounting dimensions.
