About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX350-10
The AirTAC SAIJ200X350-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 340-350 mm usable travel window, letting you dial back the nominal 350 mm stroke by up to 10 mm during commissioning. This bore generates 15708 N of push force at 0.5 MPa, making it suited for heavy-duty positioning.
This variant uses an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set omits FB, CA, CB and CR options, utilizing Basic, FA, LB, TC, FTC, TCM1 and TCM2 interfaces.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX350-10 Is Used
Heavy Press Setup
Fine-tune the 340-350 mm travel window during heavy press commissioning to achieve exact bottom-dead-center positioning without external shims.
Pallet Changeover
Adjust the retract end-stop by 10 mm on the fly to accommodate varying pallet sizes on a high-thrust conveyor line.
Large Assembly Jigs
Dial in the exact end-of-stroke position for large automotive assembly jigs where a fixed 350 mm stroke would require custom spacers.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX350-10 the Right Cylinder?
Choose this 200 mm bore when your application requires up to 15708 N push force at 0.5 MPa; stepping down to a 160 mm bore yields 10053 N if your load is lighter. The 10 mm rear adjuster allows fine end-position tuning without adding external stops, which is ideal for product-size changeovers. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air—use SAIL or BSAI for locking needs.
Because the 350 mm stroke is long, the 40 mm rod diameter and M36x2 thread still require an external guide to prevent excessive side-loading. To match an ISO 15552 replacement, verify the 200 mm bore, 350 mm stroke, 10 mm adjuster, PT G3/4 port, and mounting style.
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 SAIJ200 Adjustable Cylinder SAIJ200AX350-10 FAQ
The rear adjusting screw acts as a mechanical stopper that lets you trim the effective travel back by up to 10 mm, creating a 340-350 mm usable stroke window. It sets the end position but does not lock the load without live air pressure.
At 0.5 MPa, the SAIJ200X350-10 provides 15708 N of push force and 15080 N of pull force. It can reach a maximum push force of 21991 N at 0.7 MPa.
