About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX140-30S
The AirTAC SAIJ200X140-30-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 110-140 mm, allowing you to dial back the 140 mm nominal stroke by up to 30 mm during machine commissioning. Belonging to the 200 mm bore class, it generates a substantial 15708 N of push thrust at 0.5 MPa and 21991 N at 0.7 MPa. The extruded aluminum barrel incorporates sensor grooves on both sides, and because this unit includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise end-of-stroke detection.
This model features a robust 40 mm piston rod with an M36x2 thread, utilizing SUS420J2 stainless steel (code A) for enhanced rod durability against lateral stress. Pneumatic connections use PT tapered G3/4 ports, and variable air cushions at both ends manage deceleration. The rear adjuster acts strictly as a travel stop to set the retract end-position without swapping cylinders or adding external stops; it does not hold the load. For true load-holding without live air pressure, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX140-30S Is Used
Heavy Pressing Operations
Dial in the exact 110-140 mm end-position for high-force pressing and forming tasks, ensuring perfect material displacement without re-mounting hardware.
Product Changeover
Quickly adapt machinery to new part sizes by turning the rear adjuster, saving setup time and eliminating the need to swap out entire ISO 15552 cylinders.
Automated Assembly Lines
Use the precise retract stop to tune heavy clamping or end-of-line operations on large components, leveraging the 15708 N push force safely.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX140-30S the Right Cylinder?
Choose this 200 mm bore adjustable-stroke cylinder when your application requires high force and variable end-stop positioning. If you need slightly less thrust, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, whereas this 200 mm bore provides 15708 N at the same pressure. The adjustable stroke is ideal for fine-tuning the retract position during product changeovers, offering a setup advantage over a fixed-stroke SAI cylinder. To match this exact configuration for an ISO 15552 replacement, specify the 200 mm bore, 140 mm stroke, 30 mm adjustment, PT G3/4 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet. Even though the stroke is 140 mm, the heavy 40 mm rod and high thrust mean you should always verify external guiding if any side loads are present.
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 SAIJ200AX140-30S 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 0.7 MPa, the push force increases to 21991 N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the 140 mm nominal stroke down to as little as 110 mm. This allows fine-tuning of the retract end-position during commissioning without needing external stops, though it does not lock the load without live air.
