About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-40S
The AirTAC SAIJ200X220-40-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty tasks, delivering a substantial 15708N push force at 0.5MPa. It features a 220mm nominal stroke paired with a rear mechanical adjuster that allows you to trim the effective travel back by up to 40mm, creating a precise 180-220mm usable window for exact end-position tuning during commissioning.
This variant includes a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and ships with a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the PT tapered port threads ensure a robust pneumatic seal for high-flow operations.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-40S Is Used
Heavy-Duty Pressing
Delivers up to 21991N of push force at 0.7MPa for assembling large components, with the 40mm adjuster allowing precise bottoming-out depth control.
Product Changeover
Quickly dial in the 180-220mm travel window during line format changes, accommodating different product heights without mechanical rebuilds.
Automated Lifting
Handles massive payloads using the 40mm diameter rod, while the rear stopper ensures the lift returns to an exact, repeatable home position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-40S the Right Cylinder?
Selecting this 200mm bore cylinder is ideal when your application demands extreme thrust, such as 21991N at 0.7MPa, alongside variable end-stops. If you need less force, stepping down to a 160mm bore yields 10053N at 0.5MPa, but the SAIJ200X220-40-S provides the necessary power for large pressing or lifting fixtures. Because the stroke is 220mm, you should ensure external guiding to handle side loads, as even the robust 40mm rod can deflect under heavy off-center loads without proper support.
The adjustable stroke mechanism allows you to fine-tune the retract position without swapping the cylinder or adding external stops, which is highly beneficial for product-size changeovers. Remember that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder. This model is dimensionally interchangeable per ISO 15552 and utilizes a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ200AX220-40S FAQ
At 0.5MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. If you increase the pressure to 0.7MPa, the push force rises to 21991N.
The rear adjuster acts as a mechanical stop that lets you shorten the 220mm nominal stroke by up to 40mm, providing a usable travel window of 180-220mm. It sets the end position but does not lock the load without continuous air pressure.
