About the Airtac SAI200 Standard Cylinder SAI200AX350S
The AirTAC SAI200X350-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides 15708 N push force at 0.5 MPa and 21991 N at 0.7 MPa, making it a robust choice for high-thrust linear motion. The 350 mm stroke is ideal for moving large masses or executing long-travel clamping operations.
This variant features a SUS420J2 stainless steel piston rod for superior corrosion resistance and includes a magnet for proximity sensing. The extruded aluminum barrel incorporates sensor grooves on both sides, allowing seamless mounting of CMSE or DMSE switches without additional brackets.

Where the Airtac SAI200 Standard Cylinder SAI200AX350S Is Used
Heavy Metal Stamping
Provides the immense 15708 N push force required to form thick steel plates and operate massive press dies.
Large Press Transfer
Executes the 350 mm stroke needed to move heavy automotive chassis components between stamping stations reliably.
Industrial Waste Baling
Drives the heavy compaction ram in large-scale recycling facilities, utilizing its 21991 N force at 0.7 MPa.
Is the Airtac SAI200 Standard Cylinder SAI200AX350S the Right Cylinder?
Select this 200 mm bore when the 160 mm class (10053 N at 0.5 MPa) lacks sufficient thrust for your heaviest loads. For this 350 mm stroke, be mindful of side-load forces; long unsupported rods can bend under lateral stress. Use external guide rails or a fully guided cylinder to prevent rod-bearing wear and ensure smooth operation.
This unit uses a PT tapered G3/4 port and a standard ISO 15552 mounting interface, making it a direct drop-in replacement for other ISO 15552 profile cylinders. It includes a magnet (-S) for sensors. If the machinery must hold a load vertically without continuous air pressure, the cushion will not act as a brake; instead, integrate the SAIL locking variant or an external pilot-operated check valve.
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.
