The AirTAC AirTAC SAI200X800-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 800mm 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 SAI200X800-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa, making it well-suited for moving massive loads over its 800 mm stroke. The extruded aluminum barrel design omits tie rods, ensuring a clean exterior that resists debris accumulation.
This specific configuration includes a magnetic piston for use with CMSE and DMSE sensor switches, which ride securely in the dual side grooves. It utilizes standard carbon steel for the piston rod and features PT tapered port threads. For environments requiring elevated temperature resistance, the standard TPU seals can be swapped for Viton (H) or NBR (N) alternatives, while the SAIL variant offers an integrated locking mechanism for safety.

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 up to 21991 N at 0.7 MPa to drive large metal forming and heavy-duty stamping presses.
Actuates large robotic welding fixtures and positions heavy chassis components along the 800 mm travel.
Pushes fully loaded industrial pallets between conveyor lines, utilizing the robust 32 mm rod and G3/4 ports.
Selecting this 200 mm bore cylinder is appropriate when applications exceed the 10053 N push force available from the 160 mm bore at 0.5 MPa. Operating speed ranges from 30-500 mm/s, regulated by adjustable air cushions at both ends that absorb kinetic energy at stroke completion. Because this model features an 800 mm stroke, the extended rod is highly susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder module is strongly recommended to prevent premature rod-bearing wear.
This unit provides drop-in dimensional interchangeability with other ISO 15552 cylinders, simplifying machine upgrades and maintenance. It uses a G3/4 port and pairs with heavy-duty mounting accessories like TC trunnion or FA flanges. Note that standard SAI cylinders do not hold position upon loss of air pressure; if fail-safe load holding is required for vertical applications, specify the SAIL or BSAI clamp-lock series instead.
Quick checklist
At 0.5 MPa, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X800-S is dimensionally interchangeable per ISO 15552 standards. It matches standard mounting footprints, G3/4 ports, and M36x2 rod threads, allowing direct replacement of equivalent profile cylinders.
