About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX35-20
The AirTAC SAIJ200X35-20 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, featuring a rear stopper that allows you to fine-tune the end-of-stroke position. The integrated adjustment screw provides a usable travel window of 15 to 35 mm, letting you dial in the exact retract distance during commissioning without swapping out the hardware. With a 200 mm bore, it generates a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa.
This model features a 40 mm SUS420J2 stainless steel rod and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a mechanical travel stop to set deceleration limits and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX35-20 Is Used
Heavy-Duty Press Tuning
Dial in the exact 15 to 35 mm travel window during machine setup to accommodate varying material thicknesses in high-force pressing operations.
Product Size Changeover
Quickly adjust the retract stopper on the line when switching product sizes, avoiding the need to physically swap out the entire cylinder assembly.
End-Position Calibration
Fine-tune the end-of-stroke position at commissioning to compensate for mechanical wear or sensor drift in heavy industrial automation setups.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX35-20 the Right Cylinder?
Selecting this 200 mm bore model is appropriate when your process requires extreme force, delivering 15708 N of thrust at just 0.5 MPa. If your application demands less push power, stepping down to a 160 mm bore yields 10053 N at the same pressure, whereas moving up is unnecessary unless you exceed 3204 kgf at 1.0 MPa. You should choose this adjustable-stroke variant over a fixed SAI cylinder when your assembly line requires precise variable end-stops for frequent product-size changeovers. To match this ISO 15552 footprint exactly, specify the 200 mm bore, 35 mm stroke, 20 mm adjustment, PT port threads, and SUS420J2 rod material. For load-holding without live air, use an external pilot-operated check valve or consider the SAIL or BSAI series instead.

- ✓ 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 SAIJ200AX35-20 FAQ
The rear adjustment screw acts as a mechanical stop that shortens the effective travel. For this specific model, the nominal 35 mm stroke can be dialed back by up to 20 mm, creating a usable travel window of 15 to 35 mm depending on your setup.
At a 0.5 MPa operating pressure, the SAIJ200X35-20 provides a push force of 15708 N and a pull force of 15080 N. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf of thrust.
