About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-10
The AirTAC SAIJ200X155-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 145 to 155 mm. It delivers massive thrust, pushing with 21991 N at 0.7 MPa and reaching 28274 N at 0.9 MPa, making it ideal for heavy-duty actuation. The extruded aluminum barrel features sensor grooves on both sides for flexible positioning of CMSE reed and DMSE electronic switches.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and pairs with PT tapered port threads. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position without adding external stops, while the variable air cushions at both ends manage end-of-stroke deceleration.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-10 Is Used
Heavy Press Tuning
Dial in the exact 145-155 mm retract stop during heavy press commissioning to accommodate material thickness variations without machining new spacers.
Product Changeover
Adjust the end-stop rapidly on a packaging line when switching to a different pallet size, using the 10 mm trim window to set the new reject position.
Large Fixture Alignment
Fine-tune the retract position of a large machining fixture by up to 10 mm to ensure perfect clamping alignment before locking the setup.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX155-10 the Right Cylinder?
Select this 200 mm bore cylinder when your application requires up to 3204 kgf of maximum holding force at 1.0 MPa. If your load demands less force, stepping down to a 160 mm bore yields 14074 N of push at 0.5 MPa, whereas moving up is impossible as 200 mm is the largest standard size. The 10 mm adjustment range is chosen when you need precise end-position tuning at commissioning or during product changeover without swapping out the entire cylinder.
Because this is a standard 155 mm stroke under the 1500 mm maximum, it is a stock-friendly choice. Note that the rear adjuster and air cushions only set the travel end and deceleration; they do not hold the load without live air. For true load-holding without pressure, consider the SAIL or BSAI series. As a dimensionally interchangeable ISO 15552 cylinder, it matches the bore, stroke, PT port, and mounting interface of other profile cylinders.
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 SAIJ200AX155-10 FAQ
At 0.5 MPa it provides 15708 N of push force and 15080 N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 3204 kgf.
The rear adjuster screw lets you mechanically shorten the 155 mm nominal stroke by up to 10 mm, providing a usable travel window of 145 to 155 mm. It functions as a hard stop for end-position tuning and is not a lock.
