The AirTAC AirTAC SAI200X135 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 135mm 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 SAI200X135 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa. This 200 mm bore and 135 mm stroke configuration is tailored for moving massive loads in demanding industrial environments.
This specific unit incorporates a SUS304 stainless steel piston rod for superior corrosion resistance and includes PT tapered port threads. While the standard extruded aluminum barrel lacks a magnet for proximity sensing, the design retains dual-sided sensor grooves ready for CMSE or DMSE switches if a future upgrade to a -S variant is required.

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 high tonnage needed for metal forming and heavy stamping presses up to 28274 N at 0.9 MPa.
Shifts and positions large industrial molds or injection tooling securely within the 135 mm travel distance.
Actuates heavy-duty diverter gates on high-capacity bulk material conveyor lines handling aggregates.
Selecting this 200 mm bore is appropriate when the 160 mm class (providing 10053 N push at 0.5 MPa) is insufficient for your load requirements, as the SAI200X135 yields a massive 15708 N at the same pressure. Because the 135 mm stroke is relatively short, rod-bearing bending is not a primary concern here.
This model serves as a direct dimensional drop-in replacement for other ISO 15552 profile cylinders. For your build, confirm the 200 mm bore, 135 mm stroke, PT G3/4 port, and desired mounting accessory (such as a TC trunnion). Note that if air pressure is lost, this standard cylinder cannot hold a load; use the SAIL or BSAI variant for pneumatic locking requirements.
Quick checklist
At 0.5 MPa, this 200 mm 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 SAI200X200 is dimensionally interchangeable per the ISO 15552 standard, allowing it to serve as a drop-in replacement for equivalent ISO 15552 profile cylinders from other brands.
