About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-30
The AirTAC SAIJ200X270-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 240-270 mm, allowing you to dial back the 270 mm nominal stroke by up to 30 mm during commissioning. This bore delivers immense thrust, generating 15708 N of push force and 15080 N of pull force at 0.5 MPa. The piston rod is built from SUS304 stainless steel (code B) for superior corrosion resistance, and the PT tapered port threads ensure a robust, leak-free pneumatic connection.
Equipped with adjustable air cushions at both ends, this cylinder manages the deceleration of heavy loads effectively. The rear stopper mechanism sets the travel end-position without requiring external stops, but it acts purely as a physical stop and does not hold the load without live air pressure. For true load-holding in the event of air loss, you would need to integrate a separate SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external pilot-operated check valve.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-30 Is Used
Heavy Forming Presses
Dial in the exact 240-270 mm end-position for large metal stamping or forming operations, ensuring precise stroke depth without mechanical shims.
Automated Changeover
Rapidly adjust the travel stop when switching between product sizes on a high-force assembly line, minimizing downtime between production runs.
Large Mold Handling
Utilize the 15708 N push force to move heavy molds or tooling into position, relying on the SUS304 rod for durability in demanding environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-30 the Right Cylinder?
Choose this 200 mm bore when your application requires maximum output force, as it delivers up to 3204 kgf at 1.0 MPa. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, which may offer a more compact and efficient solution. The adjustable stroke is ideal for product-size changeovers on a line, letting you fine-tune the end-stop without swapping out the entire cylinder.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 270 mm stroke, 30 mm adjustment, PT port threads, and SUS304 rod material. Note that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting the FB, CA, CB, and CR variants. Because this unit features a 270 mm stroke, it is below the 300 mm threshold requiring external side-load guidance, but the substantial 40 mm rod and M36x2 thread inherently handle high mechanical stress well.

- ✓ 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 SAIJ200BX270-30 FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At its maximum operating pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 270 mm nominal stroke by up to 30 mm, creating a 240-270 mm travel window. It functions as a travel stop and does not lock or hold the load without continuous air pressure.
