About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX115-30S
The AirTAC SAIJ200X115-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates an 85-115 mm usable travel window. It delivers immense thrust, generating 15708 N of push force and 15080 N of pull force at 0.5 MPa, peaking at a 3204 kgf maximum load at 1.0 MPa. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position detection.
This configuration uses SUS420J2 stainless steel for the piston rod and features PT tapered port threads with a G3/4 connection. The integrated -S magnet supports AirTAC CMSE reed and DMSE solid-state electronic sensors. Variable air cushions at both ends decelerate the heavy 40 mm rod, while the rear stopper allows precise end-position tuning during commissioning without adding external stops.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX115-30S Is Used
Heavy Press Tuning
Fine-tune the exact bottoming position of a high-tonnage press during product changeover using the 85-115 mm travel window.
Variable End Stops
Adjust the retract distance on heavy-duty machinery without disassembling the line or replacing the cylinder.
Commissioning Setup
Dial in the precise end-position during initial machine setup to accommodate varying material thicknesses.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX115-30S the Right Cylinder?
Select this adjustable-stroke model when a machine setup requires dialing in the exact end-of-travel position on the fly, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If your application needs slightly less force, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa. For load-holding without live air pressure, note that this rear adjuster acts only as a travel stop, not a brake; you must specify a SAIL air-released lock, a BSAI clamp-lock, or an external rod lock. To match this ISO 15552 interchangeable cylinder, use a 200 mm bore, 115 mm stroke, 30 mm adjustment, PT G3/4 ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and a -S magnet.
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 SAIJ200AX115-30S FAQ
At 0.5 MPa it provides 15708 N push and 15080 N pull force. At its maximum operating pressure of 1.0 MPa, it achieves a peak load of 3204 kgf.
The rear adjuster acts as an external stopper that trims the nominal 115 mm stroke back by up to 30 mm, giving an 85-115 mm usable travel window for fine-tuning at commissioning. It does not lock the load without live air.
