About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX35-30S
The AirTAC SAIJ200X35-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 35 mm stroke back by up to 30 mm, creating a precise 5-35 mm usable travel window for exact end-position tuning. Delivering immense thrust, it generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, scaling up to 21991 N push at 0.7 MPa. This bore size uses a robust 40 mm piston rod paired with a G3/4 port to handle high flow demands.
This specific SKU is configured with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a built-in magnet (-S) for seamless position sensing with AirTAC CMSE reed or DMSE electronic solid-state switches. The extruded aluminum barrel features sensor grooves on both sides, and the SAIJ mounting set omits the FB, CA, CB, and CR options, supporting only Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX35-30S Is Used
Heavy-Duty Press Tuning
Dial in the exact 5-35 mm travel end-stop during heavy press commissioning to accommodate material thickness variations without swapping cylinders.
Product Size Changeover
Quickly adjust the retract position on automated lines when switching product sizes, using the rear stopper to set new bounds in seconds.
High-Force End Positioning
Leverage the 15708 N push force at 0.5 MPa to securely seat large components, using the adjustable window to prevent over-travel.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX35-30S the Right Cylinder?
Choose this 200 mm bore adjustable-stroke cylinder when an application demands extreme force combined with a very short, highly tunable travel window—such as heavy pressing or clamping tasks where the exact end-stop must be dialed in during commissioning without adding external physical stops. If your application requires less force, stepping down to a 160 mm bore yields 10053 N push at 0.5 MPa, whereas moving up is not possible as this is the largest standard ISO 15552 size. Remember that the rear adjuster acts only as a travel stop and the air cushions provide deceleration; neither will hold a load without live air pressure, so for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder instead. Because the nominal 35 mm stroke is short, side-loading is minimal, but always ensure the 40 mm rod thread and rod diameter are properly aligned to prevent binding.
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 SAIJ200AX35-30S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
The rear adjusting screw acts as an external stopper that allows you to shorten the 35 mm nominal stroke by up to 30 mm, resulting in a usable travel window of 5 to 35 mm. It functions as a travel stop for end-position tuning, not as a lock, and does not hold the load without continuous air pressure.
