About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-40S
The AirTAC SAIJ200X105-40-S is a double-acting ISO 15552 profile cylinder featuring a rear mechanical adjuster that trims the nominal 105 mm stroke back by up to 40 mm, yielding a usable travel window of 65 to 105 mm. Delivering 15708 N of push force at 0.5 MPa, this large-bore actuator is built for heavy-duty positioning. It includes a magnetic piston for position feedback and uses a SUS420J2 stainless steel rod for superior corrosion resistance.
The rear adjustment screw acts strictly as a travel stop to fine-tune the end position during commissioning or product changeover without adding external stops. It is not a locking device and will not hold the load without live air pressure. For load-holding without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-40S Is Used
Heavy Press Fine-Tuning
Dial in the exact end-of-stroke position for large pressing operations, using the 65-105 mm window to compensate for material thickness variations without changing the actuator.
Machine Changeover
Rapidly adjust the travel end-stop during product size changeovers on a packaging line, saving time by avoiding physical cylinder swaps or adding external stopper blocks.
Variable End-Stop Positioning
Set precise retraction points for heavy industrial doors or gates, utilizing the rear adjuster to set the exact 65 to 105 mm travel limit required for the specific cycle.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-40S the Right Cylinder?
Choose this 200 mm bore cylinder when an 80 mm bore (yielding 2513 N push at 0.5 MPa) is insufficient for your heavy-load positioning tasks. The adjustable 65-105 mm travel window is perfect for applications requiring variable end-stops or frequent machine setup changes, whereas a fixed-stroke SAI cylinder is better for dedicated single-purpose operations. As an ISO 15552 profile cylinder, it is dimensionally interchangeable with standard ISO 15552 mounting interfaces.
This configuration features PT tapered port threads (G3/4) and a magnetic piston compatible with AirTAC CMSE reed and DMSE electronic sensors. Because the stroke is 105 mm, side-loading is minimal, but always ensure the load is guided to prevent rod damage. Mounting options include the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ200AX105-40S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster screw allows you to shorten the 105 mm nominal stroke by up to 40 mm, creating a usable travel window of 65 to 105 mm. This stopper only sets the end position and does not lock the load without air pressure.
