About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-100
The AirTAC SAIJ200X170-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty operations. It yields 15708 N of push force and 15080 N of pull force at 0.5 MPa, peaking at 3204 kgf at 1.0 MPa. By turning the rear stopper screw, you can fine-tune the effective travel down from the 170 mm nominal stroke, creating a precise 70-170 mm usable positioning window without swapping hardware.
This unit features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and utilizes PT tapered port threads (G3/4) for sealed pneumatic connections. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning CMSE or DMSE electronic switches cannot be used without modification. The rear adjuster acts purely as a travel stop to set deceleration limits and does not hold the load without live air.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-100 Is Used
Heavy Press Changeovers
Dial in the 70-170 mm travel window during product family transitions to accommodate varying material thicknesses without retooling the entire press setup.
Large Assembly Positioning
Leverage the 15708 N push force to seat heavy components, using the rear stopper to precisely tune the final landing position at machine commissioning.
Variable End-Stop Tuning
Adjust the deceleration point on the fly for heavy payloads moving at speeds up to 500 mm/s, ensuring soft stops without adding bulky external shock absorbers.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-100 the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application requires extreme force, as stepping down to a 160 mm bore reduces the push force at 0.5 MPa to 10053 N. Choose this adjustable-stroke variant over a fixed SAI model when your machine setup requires frequent product-size changeovers or exact end-position commissioning across a 70-170 mm window. Because the nominal stroke is 170 mm, an external guide is recommended to manage side loads, as even the robust 40 mm rod and M36x2 thread cannot indefinitely support heavy unsupported masses.
For a true ISO 15552 replacement match, verify the 200 mm bore, 170 mm nominal stroke, 100 mm adjustment range, PT G3/4 port, and the absence of a magnet. If your process demands load-holding without continuous live air pressure, the rear adjuster here will not act as a brake; you must integrate an external rod lock or pilot-operated check valve, or switch to a SAIL or BSAI cylinder series.

- ✓ 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 SAIJ200AX170-100 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At its maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to trim the effective travel back from the 170 mm nominal stroke by up to 100 mm, resulting in a usable 70-170 mm positioning window. This stopper only sets the travel end and does not lock the load without live air pressure.
