About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-100
The AirTAC SAIJ200X100-100 is a double-acting ISO 15552 profile cylinder featuring a robust 200mm bore and a 100mm nominal stroke. Equipped with a rear mechanical adjuster, it provides a usable travel window of 0 to 100mm, allowing you to dial back the full stroke precisely without adding external stops. It delivers massive thrust, generating 15708N of push force and 15080N of pull force at a 0.5MPa operating pressure, making it suitable for heavy-duty industrial handling.
This model uses a SUS420J2 stainless steel piston rod (material code A) paired with a PT tapered port thread. The extruded aluminum barrel incorporates sensor grooves on both sides for direct switch mounting. While the rear adjuster and variable air cushions fine-tune end-of-travel deceleration, neither component acts as a lock; this cylinder cannot hold a load without continuous live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-100 Is Used
Heavy Press Tuning
Dial in the exact 0-100mm travel window during machine commissioning to apply precise contact force without physically swapping out cylinders.
Product Changeover
Quickly adjust the retract end-stop on packaging lines when switching to a different product size, saving setup time.
Variable End Stops
Use the rear screw to modify the effective stroke length on the fly for heavy-duty assembly lines requiring flexible positioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-100 the Right Cylinder?
Select this 200mm bore adjustable cylinder when your application requires exact end-position tuning during commissioning or frequent product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If your process demands less force, stepping down to a 160mm bore yields 10053N of push force at 0.5MPa, whereas scaling up is generally unnecessary given this model's 3204kgf maximum capacity at 1.0MPa.
To replace an ISO 15552 cylinder, verify the 200mm bore, 100mm stroke, 100mm adjustment range, PT G3/4 port, and required mounting accessories. The SAIJ series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, intentionally omitting FB, CA, CB, and CR brackets. Because the 100mm stroke is relatively short for this large bore, side-load risks are minimized, but an external guide remains recommended for heavy loads. For true position holding without air pressure, consider an AirTAC SAIL or BSAI locking cylinder instead.
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 SAIJ200AX100-100 FAQ
At 0.5MPa, it provides 15708N of push force and 15080N of pull force. At the maximum operating pressure of 1.0MPa, the push force reaches 21991N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 100mm down to 0mm. It fine-tunes the end position but does not lock the load without live air pressure.
