About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-20S
The AirTAC SAIJ200X290-20-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, featuring a single rod and a rear stroke adjuster. It delivers a substantial 15708N push force at 0.5 MPa, utilizing a robust 40mm rod with an M36x2 thread. The integrated -20mm adjuster creates a usable travel window of 270 to 290mm, allowing precise end-position tuning without swapping out the entire unit.
This variant includes an -S magnet for CMSE reed and DMSE electronic sensors, and uses a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance. The extruded aluminum barrel incorporates sensor grooves on both sides, and the PT tapered port threads ensure a secure pneumatic connection. The rear stopper functions strictly as a travel end-limit, not a load lock, relying on variable air cushions at both ends for deceleration.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-20S Is Used
Heavy Press Tuning
Dial in the exact 270-290mm end position during heavy press commissioning to accommodate material thickness variations without adding external stops.
Product Line Changeover
Quickly adjust the stroke by up to 20mm when switching between different large-scale product sizes on a high-force assembly line.
Heavy Load Positioning
Leverage the 15708N push force to move massive components, using the rear stopper to fine-tune the resting position within a 270-290mm window.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-20S the Right Cylinder?
Select this 200mm bore cylinder when an application requires extreme thrust, such as 15708N push or 15080N pull at 0.5 MPa, combined with on-the-fly stroke trimming. If the full 290mm stroke is excessive for your machine changeover, the 20mm rear adjuster trims the effective travel down to 270mm. For lower force needs, stepping down to a 160mm bore yields 10053N push force. Because the 290mm stroke exceeds 300mm when fully extended, ensure you use external guide rails to handle side loads, as the large 40mm rod only supports moderate deflection.
The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Remember that the rear adjuster is a stop, not a brake; to hold loads without live air pressure, integrate an external rod lock or choose an AirTAC SAIL or BSAI cylinder. This model is dimensionally interchangeable per ISO 15552 standards.
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 SAIJ200AX290-20S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides a push force of 15708N and a pull force of 15080N. At the maximum 1.0 MPa pressure, it achieves a maximum push force equivalent to 3204 kgf.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the nominal 290mm stroke by up to 20mm. This creates a usable travel window of 270 to 290mm, which is set during commissioning without changing the cylinder's physical mounting.
