About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX145-20S
The AirTAC SAIJ200X145-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the nominal 145 mm travel to a precise 125-145 mm window during commissioning. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, making it suitable for heavy-duty press operations. This unit features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and utilizes PT tapered port threads.
Unlike fixed-stroke actuators, this SAIJ variant integrates an external stopper at the rear to fine-tune the retract end position without swapping the barrel or adding external stops. The extruded aluminum body includes sensor grooves on both sides, and the included magnet (-S) supports CMSE reed and DMSE electronic solid-state switches for exact position feedback. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX145-20S Is Used
Heavy Stamping Alignment
Fine-tune the 125-145 mm travel window during die changeovers to accommodate varying material thicknesses without physically re-shimming the press.
Variable End-Stop Setup
Dial in the exact retract position on heavy assembly machinery, using the rear screw to set precise lower bounds for large component seating.
High-Force Clamping
Leverage the 15708 N push force at 0.5 MPa to secure massive workpieces, adjusting the clamping depth by up to 20 mm directly at the cylinder.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX145-20S the Right Cylinder?
Select this 200 mm bore actuator when an application demands exceptionally high force and the ability to trim the end-of-stroke position by up to 20 mm for product changeovers. If you need slightly less thrust and a more compact footprint, stepping down to a 160 mm bore yields 10053 N push force at 0.5 MPa. Conversely, if you require pure load-holding without continuous air pressure, a plain SAIJ is insufficient; you should pivot to the SAIL (air-released lock) or BSAI (clamp-lock) series instead. For a drop-in ISO 15552 replacement, match the 200 mm bore, 145 mm stroke, PT port, and specify the -S magnet.
Because the 145 mm stroke is relatively short for this massive bore, side-loading is less of a concern than with long-stroke units, but the substantial 40 mm rod diameter and M36x2 thread provide excellent mechanical rigidity for absorbing offset loads. The standard speed range for this bore size is 30-500 mm/s. Mounting options are limited to the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ200AX145-20S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can reach a maximum push force of 21991 N at 0.7 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 145 mm down to 125 mm. This allows precise end-position tuning at commissioning without replacing the cylinder.
