About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-40
The AirTAC SAIJ200X220-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty operations. It yields 15708N push and 15080N pull force at 0.5 MPa, scaling up to a maximum of 3204 kgf at 1.0 MPa. By featuring a 40mm adjustment range, this unit allows you to fine-tune the effective travel anywhere between 180mm and 220mm without swapping out the entire actuator.
This model incorporates an SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and uses PT tapered port threads with a G3/4 connection. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is configured without a magnet. The rear stopper screw acts purely as a travel end-deceleration point, meaning it cannot hold a load without continuous live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-40 Is Used
Heavy Machinery Setup
Fine-tune the 180-220mm travel window during heavy press commissioning to achieve exact bottom-dead-center positioning without machining new spacers.
Product Size Changeovers
Quickly adjust the stroke end point by up to 40mm on packaging lines accommodating different large-format product dimensions.
High-Force Positioning
Leverage the 15708N push force at 0.5 MPa to move heavy pallets or molds while relying on the rear stopper to dial in the exact retraction point.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-40 the Right Cylinder?
Selecting this 200mm bore actuator is appropriate when your application requires extreme force, such as 15708N at 0.5 MPa, and precise end-position tuning during commissioning. If your setup does not require the full 220mm travel, the integrated 40mm adjuster allows you to dial back the stroke to a 180mm minimum, preventing the need to bolt on external stops or order a custom fixed-length SAI cylinder. For load-holding without live air pressure, you must integrate an external pilot-operated check valve or switch to an AirTAC SAIL or BSAI locking cylinder.
Because the 220mm stroke is relatively short for this massive bore, side-loading is less of a concern than with long-stroke variants, but the substantial 40mm rod diameter and M36x2 thread still require solid external guiding to prevent binding. To replace an existing ISO 15552 cylinder, match the 200mm bore, 220mm stroke, PT G3/4 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this adjustable series.

- ✓ 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 SAIJ200AX220-40 FAQ
At 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At its maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf. The operational speed range is 30-500 mm/s.
The rear adjuster acts as a mechanical stop that allows you to shorten the 220mm nominal stroke by up to 40mm, providing an effective travel window of 180-220mm. It is a travel stop for end-position tuning, not a lock, and cannot hold a load without continuous air pressure.
