The AirTAC AirTAC SAI200X115 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 115mm 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 SAI200X115 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. The 115 mm stroke is optimal for high-thrust pressing, heavy clamping, and large-mold actuation where massive kinetic energy transfer is required over a short, controlled distance.
This specific configuration features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in humid or chemically exposed settings. The extruded aluminum barrel includes sensor grooves on both sides, and the adjustable air cushions at both ends absorb high-impact masses. Note that this variant does not include a magnet; position sensing requires external limit switches.

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 thrust needed to seat large bearings or form thick gauge sheet metal in automated press lines.
Drives heavy industrial molds and platens over short 115 mm strokes with reliable kinetic energy and adjustable end-cushioning.
Secures large fabricated structures or heavy castings during machining operations where absolute rigidity is paramount.
Select this 200 mm bore when 160 mm (10053 N push at 0.5 MPa) cannot generate enough force for your largest actuators. Because the stroke is 115 mm, side-load bending is less severe than in long-stroke units, but the massive moving mass still dictates rigid mounting. Use FA or FB flanges to handle the high direct loads. For applications needing secure position holding without air pressure, the SAIL pneumatic lock or BSAI bidirectional clamp-lock variants are required, as a standard cylinder will drift.
To replace an ISO 15552 unit, match the 200 mm bore, 115 mm stroke, PT G3/4 port, and appropriate mounting accessory. This model lacks the -S magnet option, so if your control system relies on internal cylinder reed switches, you must specify the -S suffix on your order.
Quick checklist
At a 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X115 is dimensionally interchangeable with other ISO 15552 profile cylinders. You must match the 200 mm bore, 115 mm stroke, and G3/4 port size for a seamless drop-in installation.
