About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-100
The AirTAC SAIJ200X260-100 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa. By integrating a 100 mm adjustment mechanism at the rear, this unit allows you to trim the effective travel back from its 260 mm nominal stroke, creating a highly versatile 160-260 mm usable positioning window.
Unlike standard fixed-stroke actuators, this model lets you dial in the exact retract end-position during commissioning without adding external stops. The 40 mm piston rod features an M36x2 thread and is built from SUS420J2 stainless steel (code A) for superior corrosion resistance. It uses PT tapered port threads (G3/4) and relies on 50 mm variable air cushions at both ends to decelerate heavy loads smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-100 Is Used
Heavy Machinery Changeover
Adjust the 160-260 mm travel window on the fly to accommodate different large-format product sizes without swapping out the entire actuator assembly.
Press End-Position Tuning
Fine-tune the retract stop during commissioning to achieve precise bottoming out for heavy pressing tasks, leveraging the 15708 N push force at 0.5 MPa.
Large Assembly Jigs
Utilize the M36x2 threaded SUS420J2 stainless rod in rugged fixturing where the 100 mm adjustment range allows for flexible alignment during equipment setup.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-100 the Right Cylinder?
Choose this 200 mm bore actuator when an application requires extreme force that smaller bores cannot provide, such as replacing a 160 mm bore cylinder that only pushes 10053 N at 0.5 MPa. The 100 mm adjustment range is ideal for product-size changeovers on a line, allowing operators to reset the retract distance rapidly. Because the nominal stroke is 260 mm, an external guide is recommended to handle side loads, as even the robust 40 mm rod can deflect under heavy off-center forces over extended travel.
When specifying a replacement, ensure you match the 200 mm bore, 260 mm stroke, 100 mm adjustment code, PT G3/4 port, and the SUS420J2 rod material. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Note that the rear adjuster and air cushions act only as travel stops and deceleration devices; they will not hold a load without continuous air pressure. For positive load-holding, consider an external rod lock or the AirTAC BSAI clamp-lock series.
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 SAIJ200AX260-100 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At the maximum pressure of 1.0 MPa, the push force reaches 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 260 mm nominal stroke by up to 100 mm, providing an effective travel range of 160 to 260 mm. It requires live air to function and does not lock the piston in place without pressure.
