About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX280-100
The AirTAC SAIJ200X280-100 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers immense thrust, generating 15708N of push force and 15080N of pull force at 0.5 MPa. By turning the integrated rear stopper screw, you can shorten the nominal travel, creating a precise 180-280mm usable stroke window without changing the unit.
This heavy-duty actuator features a 40mm stainless steel (SUS304) piston rod and PT tapered port threads. Extruded from aluminum with sensor grooves on both sides, it omits the FB, CA, CB, and CR mounts, utilizing a reduced ISO 15552 mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX280-100 Is Used
Heavy Assembly Line Changeovers
Adapt the clamping travel from 180 to 280mm on the fly to accommodate different large-scale product dimensions during production line changeovers.
Press Stroke Tuning
Dial back the nominal 280mm stroke by up to 100mm during commissioning to achieve precise end-position tuning for heavy-duty pressing operations.
Large Fixture Positioning
Leverage the 15708N push force to move massive fixtures, using the rear stopper to set exact variable end-stops for different fixture sizes.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX280-100 the Right Cylinder?
Choose this 200mm bore size when your application requires extreme force that a 160mm bore cannot provide, as the 160mm option yields 10053N push force at 0.5 MPa compared to this model's 15708N. An adjustable stroke is ideal for product-size changeovers on a line, letting you fine-tune the end position at commissioning rather than swapping cylinders or adding external stops.
When matching an ISO 15552 replacement, verify the 280mm stroke, 100mm adjustment, PT ports, and SUS304 rod material. Since the stroke is 280mm, the long unsupported travel necessitates an external guide to prevent side-loading damage. Remember that the rear adjuster acts only as a travel stop, not a lock; for load-holding without live air pressure, use an external rod lock or select an AirTAC SAIL or BSAI cylinder.
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 SAIJ200BX280-100 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach a maximum push force of 3204 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the 280mm nominal stroke down to as little as 180mm. This creates a 180-280mm adjustable window, but it only sets the travel end and does not lock the load without live air pressure.
