About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-20S
The AirTAC SAIJ200X750-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers immense thrust, providing 15708N of push force and 15080N of pull force at 0.5 MPa. By integrating a 20mm adjustment mechanism at the retract end, this model creates a precise 730-750mm usable travel window, allowing you to dial in the exact end position without swapping out the entire unit.
This variant features a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and includes a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and fluid is supplied via PT tapered G3/4 ports. Because the stroke is 750mm, relying on the 40mm rod diameter alone is insufficient; an external guide rail is highly recommended to manage side loads and prevent rod binding.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-20S Is Used
Long-Stroke Pressing
Dial in the exact 730-750mm end-stop for large assembly presses, ensuring precise clamping force on oversized parts without external spacers.
Machine Changeover
Fine-tune the retract position during product size transitions on a production line, saving time by adjusting the rear screw rather than replacing the cylinder.
Heavy Material Handling
Position heavy pallets or structural frames accurately, using the 15708N push force at 0.5 MPa to move loads while guiding the rod externally to prevent binding.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-20S the Right Cylinder?
Selecting this 200mm bore size is appropriate when your application requires maximum force, stepping up from a 160mm bore that yields 10053N of push force at 0.5 MPa. An adjustable-stroke cylinder is chosen over a fixed-stroke SAI when you need on-the-fly end-position tuning during machine commissioning or product changeover, eliminating the need to bolt on external physical stops.
For a true ISO 15552 replacement match, verify the 200mm bore, 750mm nominal stroke, 20mm adjustment range, PT G3/4 port, and the -S magnet requirement. The rear adjuster acts solely as a travel stop and deceleration point; it will not hold the load without continuous live air pressure. For fail-safe load holding, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ200AX750-20S FAQ
At 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. The operating speed range is 30-500 mm/s, and it supports a maximum operating pressure of 1.0 MPa.
The rear adjuster screw allows you to shorten the 750mm nominal stroke by up to 20mm, creating a 730-750mm usable travel window. It functions as a mechanical stop to fine-tune the retract end position; it is not a lock and will not hold the load without live air pressure.
