About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX270-30S
The AirTAC SAIJ200X270-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 240-270 mm usable travel window, letting you trim the nominal 270 mm stroke by up to 30 mm during commissioning. Delivering a robust 15708 N push force at 0.5 MPa, it is built for heavy-duty tasks. This configuration includes a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and a magnet for CMSE or DMSE sensors.
Unlike fixed-stroke alternatives, this model allows precise end-position tuning without adding external stops. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting. Remember that the rear adjuster acts as a travel stop and relies on live air; it does not function as a lock, so explore SAIL or BSAI types if you require true load-holding without pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX270-30S Is Used
Variable End Stops
Dial in the 240-270 mm travel window during machine commissioning to accommodate varying part sizes without swapping cylinders.
Product Changeover
Quickly adjust the retract end-position on automated lines when switching to a new product run, saving setup time.
Sensor-Ready Setup
Utilize the integrated magnet with DMSE solid-state or CMSE reed switches for precise end-of-stroke detection in heavy-duty cycles.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX270-30S the Right Cylinder?
Choose this 200 mm bore when 15708 N of thrust at 0.5 MPa is required; if your application needs less force, stepping down to a 160 mm bore yields 10053 N. The adjustable 240-270 mm window is ideal for product changeovers where exact end-stops vary. Because the 270 mm stroke is substantial, ensure external guiding is used to prevent excessive side loading on the 40 mm rod.
For a seamless ISO 15552 replacement, match the 200 mm bore, 270 mm stroke, 30 mm adjustment, PT tapered port threads, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR. Speeds range from 30-800 mm/s.

- ✓ 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 SAIJ200AX270-30S FAQ
At 0.5 MPa operating pressure, it provides 15708 N of push thrust and 15080 N of pull thrust. It can reach up to 3204 kgf at the maximum 1.0 MPa pressure.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the 270 mm nominal stroke down to 240 mm. This creates a 240-270 mm usable window for fine-tuning end positions without replacing the cylinder.
