The AirTAC Airtac SAI100 Standard Air Cylinder SAI100BX850 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 850mm stroke, G1/2 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 SAI100X850 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a robust push force of 3927 N at 0.5 MPa, extending an 850 mm stroke to drive substantial loads across long distances. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration incorporates a SUS304 stainless steel rod for superior corrosion resistance in harsh environments. It uses PT tapered port threads and lacks a piston magnet, meaning it is built purely for pneumatic actuation without external position sensing. Adjustable air cushions at both ends absorb kinetic energy at stroke extremes, protecting the mechanism from impact.

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.
Drives large pallet handling systems over 850mm strokes, utilizing the 3927N push force to move heavy goods smoothly along material flow lines.
Ejects formed metal or plastic parts from heavy machinery, where the SUS304 rod withstands potential coolant splashes and harsh factory conditions.
Actuates large lifting or pushing arms in automated storage and retrieval systems, relying on adjustable cushions to stop 850mm movements safely.
Selecting this 100 mm bore over the smaller 80 mm variant upgrades your push force from 2513 N to 3927 N at 0.5 MPa, while stepping up to a 125 mm bore would yield 6136 N. The 850 mm stroke requires careful attention to mechanics; long unsupported rods are prone to bending under side loads. To prevent premature wear on the rod bearing and seals, implement an external guide rail or use a guided cylinder design for heavy off-center loads.
As a drop-in replacement per ISO 15552 mounting dimensions, it matches standard FA, FB, and TC accessory footprints. If your application requires intermediate stopping or fail-safe load holding without constant air pressure, note that the standard SAI cylinder will drift; you should specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead.
Quick checklist
At a 0.5 MPa operating pressure, the SAI100X850 generates a push force of 3927 N and a pull force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X850 is a true ISO 15552 profile cylinder. Its standardized mounting interface and PT G1/2 port make it dimensionally interchangeable with other ISO 15552 cylinders of the same bore size.
