The AirTAC AirTAC SAI200X85 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 85mm 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 SAI200X85 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty positioning tasks. Operating at 0.5 MPa, it generates 15708 N of push force and 15080 N of pull force, making it well-suited for high-mass automation. The 85 mm stroke provides compact actuation where full travel is not required.
This unit features a SUS304 stainless steel rod for superior corrosion resistance in harsh or washdown environments. It uses PT tapered port threads and incorporates an extruded aluminum barrel with sensor grooves on both sides for flexible switch mounting.

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 15708 N push force at 0.5 MPa required to actuate large stamping presses and heavy-gauge metal forming dies.
Handles large chassis components and heavy powertrain modules during automated robotic welding and fixturing.
Shifts substantial injection molding tooling and heavy industrial molds safely within a compact 85 mm travel distance.
Select this 200 mm bore when the 160 mm class (10053 N push at 0.5 MPa) cannot provide enough thrust. Because the stroke is under 300 mm, rod-bearing bending risks are minimal, but the substantial weight of the 200 mm piston still requires rigid mounting. The cylinder uses a G3/4 port and an M36x2 rod thread. For applications requiring position holding without air pressure, use the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock, as the standard adjustable air cushions only decelerate the piston near stroke end and will not hold a load.
Quick checklist
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can reach up to 21991 N push at 0.7 MPa.
No, the standard SAI200X85 is double-acting and will drift if air pressure is lost. The adjustable cushions only decelerate the piston at stroke end. For holding loads, use the SAIL or BSAI lock variants.
