About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-100
The AirTAC SAIJ200X290-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits up to 100 mm of travel reduction. This creates a highly flexible 190-290 mm usable stroke window, allowing precise end-position tuning during commissioning or product changeovers without swapping out the physical barrel. Belonging to the 200 mm bore class, it delivers immense thrust, generating 28274 N of push force at 0.9 MPa.
This heavy-duty actuator incorporates a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and utilizes PT tapered port threads. It supports a maximum operating speed of 30-500 mm/s and includes adjustable air cushions at both ends to decelerate massive loads. The extruded aluminum barrel features sensor grooves on both sides, ready to accept CMSE reed or DMSE solid-state switches if a magnet is specified later.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-100 Is Used
Heavy Press Tuning
Dial in the exact end-position for massive forming or press operations, using the 190-290 mm window to compensate for material thickness variations without machine teardown.
Product Changeover Stops
Quickly adapt a heavy-duty packaging line to different pallet sizes by turning the rear adjuster, shifting the retraction point up to 100 mm to handle new dimensions.
Large Assembly Positioning
Position large automotive or industrial components precisely during assembly, relying on the 28274 N force at 0.9 MPa to move heavy fixtures securely.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-100 the Right Cylinder?
Selecting this 200 mm bore actuator is ideal when your application requires extreme force, such as the 15708 N push at a standard 0.5 MPa, alongside variable end-stop positioning. If your setup demands less force, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, whereas moving up is impossible as this is the largest standard SAIJ size. The integrated 100 mm adjustment mechanism is perfect for accommodating multiple product sizes on a single conveyor line, replacing the need to bolt on external stops.
For an exact ISO 15552 dimensional replacement, match the 200 mm bore, 290 mm stroke, PT ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), noting that FB, CA, CB, and CR mounts are omitted. Because the 290 mm stroke approaches the mid-range of this massive cylinder, ensure external guides are used to prevent excessive side-loading on the 40 mm rod. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series.
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 SAIJ200AX290-100 FAQ
As a 200 mm bore cylinder, it provides a maximum push force of 28274 N at 0.9 MPa and a pull force of 15080 N at 0.5 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the nominal 290 mm down to 190 mm. It only sets the end position and does not lock the load without live air pressure.
