Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-100S
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 105mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-100S
The AirTAC SAIJ200X105-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 105 mm stroke that can be dialed back by up to 100 mm, yielding a highly versatile 5-105 mm usable travel window. Delivering massive thrust with 15708 N push force at 0.5 MPa, it handles the heaviest pneumatic positioning tasks. The barrel is extruded aluminum, distinctly avoiding tie-rod construction, and features sensor grooves on both sides.
This specific SKU is configured with a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and includes a magnet (-S) for position detection. The integrated magnet interfaces precisely with AirTAC CMSE reed switches and DMSE solid-state electronic sensors. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning; it is not a locking device and will not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-100S Is Used
Heavy Press Tuning
Dial in the exact clamping end-position on heavy stamping or press operations, using the 5-105 mm window to compensate for material thickness variations without retooling.
Multi-Product Forming
Adapt a single high-force forming station to various part lengths by adjusting the retract stop, leveraging the 15708 N thrust to shape thick materials.
Assembly Line Changeover
Rapidly reconfigure large automated assembly actuators during product family changeovers by turning the rear adjuster rather than physically swapping cylinders.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-100S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when an application demands extreme force that smaller bores cannot provide, such as replacing twin 125 mm cylinders (which offer 6136 N push each at 0.5 MPa). The wide 100 mm adjustment range is chosen over a fixed-stroke SAI cylinder when a machine must accommodate multiple product sizes or require precise end-position tuning at setup without swapping hardware. Fluid must be air filtered to 40 um, operating at 0.15-1.0 MPa.
Because the 105 mm stroke is relatively short for this massive bore, side-load risks are minimized compared to longer strokes, but external guides are still recommended for heavy off-center loads. The PT tapered port thread is standard for this bore. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR. If true load-holding is required without continuous air pressure, this cylinder is insufficient; specify an AirTAC SAIL (air-released lock) or BSAI (clamp-lock) instead.
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 SAIJ200AX105-100S FAQ
At 0.5 MPa, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. The maximum thrust is 3204 kgf at 1.0 MPa. The operational speed range for this bore size is 30-500 mm/s.
The rear adjuster acts as a mechanical stop that allows you to shorten the 105 mm nominal stroke by up to 100 mm, creating a usable travel window of 5 to 105 mm. It only sets the end position and deceleration; it does not lock the load without live air pressure.
