About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-40
The AirTAC SAIJ200X100-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, letting you dial back the 100 mm nominal travel by up to 40 mm to achieve a precise 60-100 mm usable window. It delivers immense thrust, pushing 15708 N at 0.5 MPa and reaching 28274 N at 0.9 MPa, making it suitable for heavy-duty press operations. This configuration features a SUS420J2 stainless steel rod for enhanced corrosion resistance and PT tapered port threads.
The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning; it does not lock the load without live air. For position holding without pressure, an external rod lock or related types like SAIL or BSAI are required. This 200 mm bore uses a robust 40 mm rod and M36x2 thread, handling speeds of 30-500 mm/s, and supports mounting options Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-40 Is Used
Heavy Pressing Operations
Provides up to 28274 N of push force at 0.9 MPa for forming and stamping, with the 40 mm adjuster allowing precise bottoming-out height calibration.
Product Size Changeovers
Quickly adapt the 60-100 mm travel window on a production line when switching between different material thicknesses or product dimensions.
Heavy Machinery Actuation
Drives large industrial gates or heavy tooling platforms reliably, utilizing the robust 40 mm SUS420J2 rod and M36x2 thread for high structural integrity.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-40 the Right Cylinder?
Select this 200 mm bore when your application requires maximum force—stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N. Choose this adjustable-stroke SAIJ over a fixed SAI when you need to trim the end-of-travel position during machine setup or product changeover without adding external physical stops. To match an ISO 15552 replacement, verify the 200 mm bore, 100 mm stroke, 40 mm adjustment, PT G3/4 ports, and the specific mounting accessory.
Because the stroke is 100 mm, side-loading is less of a concern than with longer travels, but the heavy 40 mm rod still requires proper guiding to prevent binding. Remember that the rear adjuster and the variable air cushions at both ends only decelerate the travel; they do not function as a brake. If the load must be held without constant air pressure, integrate a pilot-operated check valve or switch to a SAIL or BSAI locking 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 SAIJ200AX100-40 FAQ
At 0.5 MPa operating pressure, the push force is 15708 N and the pull force is 15080 N. At 0.9 MPa, the push force increases to 28274 N.
The rear adjusting screw acts as a mechanical stop that lets you shorten the 100 mm nominal stroke by up to 40 mm, providing a usable travel window of 60 to 100 mm for fine-tuning end positions without swapping the cylinder.
