The AirTAC AirTAC SAI200X55 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 55mm 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 SAI200X55 is a heavy-duty double-acting ISO 15552 profile cylinder engineered for immense thrust, delivering 15708 N of push force and 15080 N of pull force at 0.5 MPa. The 55 mm stroke provides rapid, high-impact linear motion within a compact footprint. Because the barrel is an extruded aluminum profile rather than a tie-rod design, it integrates cleanly into modern machinery.
This specific configuration features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in harsh washdown or chemical environments. It utilizes PT tapered port threads, and because no magnet is specified, it ships without sensor tracks active, though the profile barrel retains its dual-side sensor grooves for future CMSE or DMSE switches if needed.

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.
Generates the 21991 N force at 0.7 MPa required to form thick-gauge steel plates in automated stamping presses.
Uses the SUS304 stainless steel rod to safely eject large plastic molds in humid or chemical-heavy production cells.
Provides rigid, high-tonnage clamping for oversized industrial fabrications and heavy machinery assemblies.
Selecting this 200 mm bore cylinder is appropriate when applications demand maximum thrust, such as 21991 N at 0.7 MPa. If your machinery requires less force, stepping down to the 160 mm bore yields 10053 N at 0.5 MPa, which may suffice and save space.
For this 55 mm stroke, side-load on the rod bearing is minimal, but the mass of the piston is substantial. Note that a standard SAI cylinder relies on adjustable air cushions at both ends to decelerate the piston; it does not hold position when air pressure is removed. If your cycle requires fail-safe load holding or drop prevention, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead of a standard SAI. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement matching the 200 mm bore, 55 mm stroke, G3/4 PT ports, and standard mounting accessories like the CA clevis or TC trunnion.
Quick checklist
At 0.5 MPa, the SAI200X55 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 SAI200X55 is dimensionally interchangeable per ISO 15552. You can match the 200mm bore, 55mm stroke, G3/4 PT ports, and mounting interface to replace other ISO 15552 profile cylinders.
