About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-50S
The AirTAC SAIJ200X290-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 240 to 290 mm. Built with an extruded aluminum barrel, it delivers massive thrust up to 15708 N at 0.5 MPa, making it suitable for heavy-duty press and clamping operations. The integrated -S magnet supports position sensing via CMSE reed or DMSE electronic switches.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and uses PT tapered port threads. The rear stopper mechanism lets you dial in the exact retract distance during commissioning, entirely removing the need to swap cylinders or bolt on external stops when product dimensions change.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-50S Is Used
Heavy-Duty Press Tuning
Dial in the exact 240 to 290 mm retract distance during machine commissioning to accommodate different workpiece thicknesses without changing the actuator.
Product Line Changeover
Quickly adjust the end stop on the fly when switching the manufacturing line to a new product size, saving hours of mechanical retooling.
High-Force Positioning
Leverage the 15708 N push force to move heavy assemblies into place while fine-tuning the final resting position via the rear screw stopper.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-50S the Right Cylinder?
Select this 200 mm bore actuator when an application demands extreme force, such as 15708 N push at 0.5 MPa, alongside precise end-position tuning. If your process requires less force, stepping down to a 160 mm bore yields 10053 N of push force. Because the 290 mm stroke exceeds 300 mm is false here, but maintaining external guidance is still recommended due to the massive 40 mm rod and heavy loads. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding, consider an AirTAC SAIL or BSAI lock cylinder.
To match this ISO 15552 interchangeable cylinder exactly, specify the 200 mm bore, 290 mm stroke, 50 mm adjustment range, PT G3/4 port, and the -S magnet. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. Operating speed ranges from 30 to 500 mm/s.
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 SAIJ200AX290-50S 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 achieves a top push force of 3204 kgf.
The rear adjuster screw allows you to shorten the nominal 290 mm stroke by up to 50 mm, creating a usable travel window of 240 to 290 mm. This stopper only sets the end position; it does not lock the load without continuous air pressure.
