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 operations requiring immense thrust. It generates a substantial 15708N push force at 0.5 MPa, scaling up to 21991N at 0.7 MPa. The extruded aluminum barrel design omits tie-rods, providing a rigid yet accessible housing for high-force automation.
This 200mm bore unit utilizes a standard carbon steel piston rod and features tapered PT port threads for secure pneumatic connections. Because it lacks a built-in magnet, position sensing requires external switches or a custom configuration. For applications needing intermediate stopping, the SAID double-rod variant offers enhanced structural support.

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 21991N force at 0.7 MPa required to form and stamp thick-gauge metal components in automated fabrication lines.
Delivers reliable push-out force for substantial injection molds, ensuring heavy parts eject cleanly without sticking.
Handles severe-duty pressing applications where 200mm bore output secures large bearings or structural pins into heavy assemblies.
Selecting this 200mm bore model is appropriate when systems demand maximum thrust exceeding 15000N at 0.5 MPa, as stepping down to a 160mm bore drops the output to 10053N. The 115mm stroke provides a compact extension length for high-force clamping or heavy ejection tasks. Operating speed ranges from 30-500 mm/s, suitable for controlled, high-inertia movements.
Mounting dimensions adhere strictly to the ISO 15552 interface, making it a drop-in replacement for any standard 200mm bore profile cylinder. Standard carbon steel rod material handles standard industrial loads, while adjustable air cushions at both ends manage end-of-stroke impact. If the machinery must maintain a static position during a complete loss of air pressure, pair this cylinder with an external pilot-operated check valve or transition to the BSAI bidirectional clamp-lock series.
Quick checklist
At 0.5 MPa, the push force is 15708N. At 0.7 MPa, it delivers 21991N, and it reaches a theoretical maximum of 3204 kgf at 1.0 MPa.
No, the standard SAI200X115 cannot hold a load without live air pressure. The adjustable cushions only decelerate the piston near stroke end. For true fail-safe holding, use the BSAI clamp-lock variant or an external rod lock.
