The AirTAC AirTAC SAI200X45 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 45mm 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 SAI200X45 is a formidable double-acting ISO 15552 profile cylinder engineered for immense thrust, generating 15708 N of push force at just 0.5 MPa. Its short 45 mm stroke is optimized for high-impact pressing, clamping, and heavy-duty ejection tasks where absolute power matters more than travel distance. The extruded aluminum barrel design omits tie rods, presenting a clean exterior that aligns perfectly with standardized ISO 15552 mounting dimensions.
Reflecting the specific configuration of this unit, it features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in harsh or washdown environments. Fluid routing utilizes PT tapered port threads. Because a -S magnet code was not specified, this version does not accommodate reed switch sensors; if position feedback is required, a model with the -S suffix and CMSE or DMSE switches would be necessary.

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 push force at 0.5 MPa needed for short-stroke metal forming, stamping, and riveting operations.
Ideal for securing large molds or heavy workpieces during machining, utilizing its 45 mm stroke to lock components firmly in place.
Delivers rapid, high-force ejection of finished pallets or heavy billets from production lines, benefiting from the robust 200 mm bore architecture.
Selecting this 200 mm bore cylinder is appropriate when a 160 mm bore (providing 10053 N push at 0.5 MPa) is insufficient for your load. The 45 mm stroke keeps the retracted length compact, which is advantageous in tight heavy-machinery layouts. Because the stroke is well under 300 mm, rod-bearing bending from side loads is minimal, though loads should still be kept axial to maximize seal life.
This model is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 profile cylinders. To match this specific configuration, ensure your setup accommodates a 200 mm bore, 45 mm stroke, PT G3/4 ports, and standard mounting accessories such as LB foot brackets or TC trunnion joints. Note that a standard SAI does not hold its load upon air loss; for fail-safe gripping, consider the BSAI clamp-lock variant or an external pilot-operated check valve.
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. If operating at 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X45 is a genuine ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other ISO 15552 cylinders. It uses PT G3/4 ports and operates at speeds between 30-500 mm/s.
