About the Airtac SAI200 Standard Cylinder SAI200AX190
The AirTAC SAI200X190 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial push force of 15708 N at 0.5 MPa, this 200 mm bore actuator is built to move massive loads reliably. The 190 mm stroke provides ample extension for large-scale pressing, lifting, and clamping operations.
This model features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid or mildly chemically washed environments. Fluid is filtered air, operating pressure ranges from 0.15 to 1.0 MPa, and it includes adjustable air cushions at both ends to decelerate heavy payloads smoothly.

Where the Airtac SAI200 Standard Cylinder SAI200AX190 Is Used
Heavy Metal Forming
Provides the robust 15708 N thrust required for bending, stamping, and forming thick metal sheets in primary manufacturing lines.
Large Assembly Presses
Drives massive components together in automotive and heavy machinery assembly, utilizing its 190 mm stroke to seat large bearings and housings.
Pallet Dispensing
Lifts and indexes heavy loaded pallets in high-throughput distribution centers, relying on the adjustable cushions to stop loads gently.
Is the Airtac SAI200 Standard Cylinder SAI200AX190 the Right Cylinder?
Select this 200 mm bore actuator when your application requires extremely high thrust that smaller bores cannot provide, such as replacing multiple smaller cylinders with a single centralized high-force unit. If 15708 N at 0.5 MPa is excessive for your payload, stepping down to the 160 mm bore (10053 N at 0.5 MPa) may optimize air consumption. Conversely, if you need extreme holding power without constant live air pressure, the SAIL variant offers an air-released lock mechanism.
Because the 190 mm stroke is under the 300 mm threshold, side-load stress on the rod bearing is minimal compared to longer strokes. However, always verify that your mounting interface—whether using FA flange, LB foot, or TC trunnion accessories—aligns perfectly with the ISO 15552 dimensions to prevent binding. This unit uses PT tapered G3/4 ports and does not include a magnet for sensor tracking.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
