The AirTAC AirTAC SAI200X275 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 275mm 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 SAI200X275 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. Delivering a substantial 15708 N of push force at 0.5 MPa, this 200 mm bore unit is built to manage massive payloads. Its 275 mm stroke provides the travel length required for large-scale positioning. The extruded aluminum barrel design omits tie-rods, yielding a cleaner profile while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
To suit demanding environments, the piston rod comes in standard carbon steel, with SUS304 stainless steel available for superior corrosion resistance. The standard seal configuration is TPU, but a high-temperature Viton (H) option is offered for applications operating near the cylinder's 70 C limit. Note that for position feedback, adding the -S magnet option enables use with CMSE or DMSE sensors along the dual barrel grooves.

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 15708 N push force required to actuate large forming presses and heavy stamping equipment.
Handles large structural components and chassis frames along the 275 mm stroke during automated welding.
Drives robust lifting mechanisms for heavy industrial pallets, utilizing the 200 mm bore capacity.
Stepping down to a 160 mm bore reduces the 0.5 MPa push force to 10053 N, which may be insufficient if your assembly requires the full 15708 N capacity of this 200 mm unit. Because the 275 mm stroke exceeds 300 mm, it is critical to evaluate side-load conditions; long unsupported rods are prone to bending under lateral stress. Employing an external guide rail or a dedicated guided cylinder will protect the rod bearing and ensure smooth travel.
This model features a PT G3/4 port and an adjustable air cushion at both ends to decelerate the piston near stroke limits. Remember that the standard SAI does not hold a load when air pressure is removed; for fail-safe load holding, integrate an external pilot-operated check valve or specify the SAIL locking variant. To guarantee a seamless ISO 15552 drop-in replacement, match the 200 mm bore, 275 mm stroke, PT port, and your required mounting accessory, such as a TC trunnion or LB foot.
Quick checklist
The SAI200X275 generates a push force of 15708 N and a pull force of 15080 N when operated at 0.5 MPa.
Yes, the SAI200X275 is dimensionally interchangeable per ISO 15552. Match the bore, stroke, and PT G3/4 port for a direct drop-in replacement.
