About the Airtac SAI200 Standard Cylinder SAI200AX225S
The AirTAC SAI200X225-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust push force of 15708 N at 0.5 MPa, this 200mm bore unit is built to move substantial loads across its 225mm stroke. The extruded aluminum barrel omits tie-rods, presenting a clean profile that drops directly into standardized ISO 15552 mounting interfaces.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid or washdown environments. Equipped with a magnet (-S), the barrel features sensor grooves on both sides for seamless CMSE or DMSE switch mounting. Fluid ports are PT (tapered) G3/4, and adjustable air cushions at both ends manage deceleration effectively within its 30-500 mm/s speed range.

Where the Airtac SAI200 Standard Cylinder SAI200AX225S Is Used
Heavy Metal Stamping
Provides the immense 15708 N push force at 0.5 MPa required to actuate large mechanical presses and form thick-gauge metal components.
Large Mold Handling
Shifts heavy injection molds or tooling blocks along the 225mm stroke, utilizing the SUS420J2 stainless steel rod to resist workshop humidity.
Bulk Pallet Diversion
Drives heavy-duty diverter arms on high-mass pallet conveyors, using adjustable air cushions to smoothly brake the 200mm bore piston.
Is the Airtac SAI200 Standard Cylinder SAI200AX225S the Right Cylinder?
Selecting this 200mm bore cylinder is appropriate when applications require extremely high thrust, such as 15708 N push force at 0.5 MPa or up to 21991 N at 0.7 MPa. If a system needs less force, stepping down to a 160mm bore yields 10053 N at 0.5 MPa, which may better suit lighter frame actuation and reduce air consumption. Because the 225mm stroke is substantial, evaluate the rod-bearing bending loads; utilizing external guide rails or a fully guided cylinder carriage is recommended to prevent side-load wear.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders without claiming exact brand equivalence. Standard mounting accessories include TC, FA, or LB brackets. Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold loads. If the machinery must maintain position during a loss of air pressure, integrate an external pilot-operated check valve or specify the SAIL (air-released lock) variant.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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.
Airtac SAI200 Standard Cylinder SAI200AX225S FAQ
The 200mm bore generates a push force of 15708 N and a pull force of 15080 N at 0.5 MPa. At 0.7 MPa, the push force increases to 21991 N.
Yes, it is dimensionally interchangeable per ISO 15552 mounting interfaces. You can drop it into existing ISO 15552 foot, flange, or trunnion brackets without altering the machine frame.
