About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX50-40
The AirTAC SAIJ200X50-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a robust 15708N push force at 0.5MPa and uses a PT tapered G3/4 port. Equipped with a SUS420J2 stainless steel rod, it handles demanding environments while maintaining standard ISO 15552 mounting dimensions.
The integrated rear stopper allows you to fine-tune the effective travel down from a 50mm nominal stroke to a 10-50mm usable window. This external adjustment screw sets the retract end-position precisely during commissioning without requiring external stops or cylinder replacement.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX50-40 Is Used
Heavy Press Fit Tuning
Dial in the exact 10-50mm insertion depth for heavy press operations without changing physical cylinder stops during product changeovers.
Large Clamp Adjustment
Adjust the retract position on the fly to accommodate varying material thicknesses in large-scale clamping fixtures.
Machine Setup Calibration
Fine-tune the end-of-stroke position during initial commissioning to perfectly synchronize heavy machinery movement.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX50-40 the Right Cylinder?
Choose this 200mm bore when the 160mm class (10053N push at 0.5MPa) is insufficient for your heavy loads. The adjustable stroke is ideal for product changeovers, letting you dial in the exact end-stop without swapping the cylinder. For load-holding without live air pressure, note that this adjuster acts only as a travel stop; you would need an SAIL or BSAI cylinder instead. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ200AX50-40 FAQ
At 0.5MPa, it provides 15708N of push force and 15080N of pull force. At 0.7MPa, the push force increases to 21991N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 50mm nominal stroke down to a minimum of 10mm, creating a 10-50mm usable travel window.
