About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-30
The AirTAC SAIJ200X200-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 170-200 mm usable travel window, allowing you to dial back the nominal 200 mm stroke by up to 30 mm during commissioning. This bore size delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, scaling up to a 3204 kgf maximum at 1.0 MPa.
Built with an extruded aluminum barrel and sensor grooves on both sides, it omits tie-rod construction. The rod is crafted from SUS420J2 stainless steel (code A) for enhanced corrosion resistance, and the PT tapered port threads ensure a tight pneumatic connection. The rear adjuster acts purely as a travel stop to fine-tune the end position, not as a lock, meaning live air is required to hold the load.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-30 Is Used
Heavy-Duty Press Tuning
Dial in the exact 170-200 mm end position for high-force pressing tasks without machining custom external stoppers.
Product Changeover
Quickly adjust the stroke by up to 30 mm on the production line when switching between slightly different product heights.
Automated Assembly
Leverage the 15708 N push force at 0.5 MPa for driving large components while fine-tuning the final resting position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-30 the Right Cylinder?
Select this 200 mm bore cylinder when an application requires extreme force combined with precise end-position tuning. If you need less thrust, stepping down to a 160 mm bore yields 10053 N push force at 0.5 MPa, but the 200 mm bore is necessary for heavy-duty presses. Choose the adjustable-stroke SAIJ over a fixed-stroke SAI when you need variable end-stops for product changeovers without swapping the cylinder or adding external stops.
For an exact ISO 15552 replacement, match the 200 mm bore, 200 mm stroke, 30 mm adjustment, PT port threads, and SUS420J2 rod material. Note that this model lacks a magnet for sensors. Because the stroke is 200 mm, standard internal air cushions handle deceleration. If you need to hold a load without live air pressure, this cylinder cannot do it; you must look to an external rod lock or the AirTAC SAIL/BSAI locking cylinder series.
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 SAIJ200AX200-30 FAQ
It features a rear adjusting screw that lets you shorten the effective travel from 200 mm down to 170 mm. This provides a 30 mm tuning window to set the exact retract end position without replacing the cylinder.
At 0.5 MPa, it provides 15708 N of push force and 15080 N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 3204 kgf.
