About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX110-20
The AirTAC SAIJ200X110-20 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing with 15708N and pulling with 15080N at 0.5 MPa. By turning the rear stopper screw, you can trim the effective travel back by up to 20 mm, creating a precise 90-110 mm usable stroke window without needing to physically swap the cylinder during machine setup.
This heavy-duty unit features a robust 40 mm piston rod and a PT tapered port thread for reliable high-flow pneumatic connections. The rod is constructed from SUS420J2 stainless steel (material code A), offering excellent resistance to corrosion and scoring in harsh environments. As an extruded aluminum profile cylinder, it includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning electronic DMSE or reed CMSE switches cannot be used without a configuration change.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX110-20 Is Used
Heavy Press Tuning
Dial in the exact 90-110 mm end position for high-tonnage pressing tasks, using the rear adjuster to compensate for material thickness variations without changing tooling.
Product Changeover
Adapt large-scale automated diverter arms to different pallet sizes on the fly by trimming the stroke up to 20 mm, ensuring gentle contact with heavy loads.
Harsh Environment Actuation
Leverage the SUS420J2 stainless steel rod for pushing or clamping operations in washdown or mildly corrosive industrial settings where carbon steel would fail.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX110-20 the Right Cylinder?
Select this 200 mm bore actuator when an application demands extreme force that smaller neighbors cannot provide, as stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053N. The adjustable stroke is ideal for production lines running mixed product sizes, allowing operators to fine-tune the 90-110 mm end position on the fly instead of installing external mechanical stops. Because the stroke is 110 mm, side-loading is minimal, but the sheer weight of the 40 mm rod means external guiding is still recommended for rigid mounting.
For an exact ISO 15552 replacement, match the 200 mm bore, 110 mm stroke, 20 mm adjustment code, PT port thread, and the SUS420J2 rod material. Remember that the rear adjuster functions strictly as a travel stop to set the deceleration point, not as a locking device. The cylinder will not hold its load without continuous live air pressure; if true load-holding is required for safety, specify an AirTAC SAIL pneumatic lock cylinder or an external rod lock instead.
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 SAIJ200AX110-20 FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708N and a pull force of 15080N. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf of thrust.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 110 mm nominal stroke by up to 20 mm. This creates a usable travel window of 90-110 mm, which can be fine-tuned during commissioning without altering the cylinder's physical mounting.
