About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX35-10S
The AirTAC SAIJ200X35-10-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty tasks requiring exact end-position tuning. Equipped with a rear mechanical stopper, it allows you to dial back the nominal 35 mm stroke by up to 10 mm, creating a precise 25-35 mm usable travel window without swapping out the hardware. Delivering 15708 N of push force at 0.5 MPa, it is built for massive loads.
This unit features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. It utilizes PT tapered G3/4 ports and a robust M36x2 rod thread. The extruded aluminum barrel provides dual sensor grooves, and the adjustable rear stopper serves strictly as a travel end deceleration device, not a load-holding lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX35-10S Is Used
Heavy Press Tuning
Fine-tune the 25-35 mm travel window during machine commissioning to set the exact contact force for a 200 mm bore pressing assembly.
Product Changeover
Quickly adjust the rear stopper by up to 10 mm to accommodate slightly different material thicknesses on the line without changing the cylinder.
High-Force End Stop
Leverage 15708 N of thrust at 0.5 MPa for robust clamping or lifting, using the built-in stopper to decelerate the load at the retract end.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX35-10S the Right Cylinder?
Select this 200 mm bore actuator when your machinery demands extreme thrust, offering 15708 N push and 15080 N pull at 0.5 MPa, alongside a 25-35 mm adjustable travel window to perfect your setup during commissioning. If your application requires less force, stepping down to a 160 mm bore yields 10053 N push force, whereas moving up is unnecessary unless you exceed 21991 N at 0.7 MPa. Choose this adjustable-stroke SAIJ model over a fixed-stroke SAI when you need on-the-fly end-stop tuning for product changeovers.
As an ISO 15552 dimensionally interchangeable cylinder, it matches standard mounting footprints using the SAIJ subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, deliberately omitting FB, CA, CB, and CR. Because the 35 mm stroke is short, external side-load guides are less critical here, but remember that the rear adjuster only sets the travel end. For true position holding without live air pressure, integrate an external pilot-operated check valve or use an AirTAC SAIL or BSAI locking cylinder instead.

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 SAIJ200AX35-10S FAQ
It features a rear adjusting screw that allows you to shorten the effective 35 mm stroke by up to 10 mm. This provides a usable travel window of 25-35 mm, letting you fine-tune the end position at commissioning without adding external stops.
At a 0.5 MPa operating pressure, the SAIJ200X35-10-S provides 15708 N of push force and 15080 N of pull force. It can reach up to 21991 N push force at 0.7 MPa.
