The AirTAC AirTAC SAI200X25 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 25mm 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 SAI200X25 is a double-acting ISO 15552 profile cylinder engineered for immense thrust in tight linear movements. It generates 15708 N of push force at 0.5 MPa, scaling up to 21991 N at 0.7 MPa. The short 25mm stroke is tailored for heavy-duty clamping or pressing tasks where absolute minimal travel is required. A standard carbon steel piston rod provides robust durability for high-impact industrial environments.
This extruded aluminum barrel design includes integrated sensor grooves on both sides for straightforward position feedback. Because no magnet is specified, adding reed or solid-state switches later requires a custom -S suffix configuration. For operations demanding flame resistance or chemical stability, the standard TPU seals can be swapped for Viton H or NBR N alternatives.

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 massive 15708 N force needed to hold thick steel sheets firmly in place during a stamping press cycle.
Ideal for short-stroke pressing operations, delivering concentrated power to seat bearings or form dense materials.
Secures heavy injection molding tooling halves with a brief 25mm stroke, ensuring zero movement during high-pressure resin injection.
Selecting this 200mm bore model is appropriate when 160mm bore falls short, as the 160mm variant only yields 10053 N at 0.5 MPa compared to the 15708 N available here. The PT tapered port thread ensures a tight, reliable pneumatic connection under high flow demands. Mounting accessories like TC trunnion or LB foot brackets follow the standardized ISO 15552 interface, guaranteeing dimensional interchangeability with other profile cylinders.
Keep in mind that a standard SAI cylinder cannot sustain a load if air pressure drops completely; the piston will drift. If your 25mm stroke application involves suspending heavy masses during an emergency stop, integrate the SAIL locking variant or an external pilot-operated check valve to prevent dangerous drops.
Quick checklist
At a 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X25 is built to the ISO 15552 standard, making its mounting interface and envelope dimensions fully interchangeable with other ISO 15552 profile cylinders like those from Festo or SMC.
