About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX300-10
The AirTAC SAIJ200X300-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers massive thrust, pushing 28274N at 0.9 MPa, making it suited for heavy-duty tasks. The built-in rear stopper allows you to fine-tune the retract end-position, creating a usable travel window of 290 to 300 mm without adding external stops.
This 200 mm bore unit incorporates a SUS420J2 stainless steel rod for enhanced durability against moisture. It uses PT tapered G3/4 ports and achieves speeds of 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if added later.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX300-10 Is Used
Heavy Press Tuning
Dial in the exact 290-300mm retract position during heavy press commissioning to accommodate material thickness variations without changing the cylinder.
Product Changeover Stops
Adjust the end-stop on the fly when switching product sizes on a high-thrust conveyor line, saving time on mechanical modifications.
Large Assembly Jigs
Provide massive 28274N thrust at 0.9MPa for large component seating while using the rear screw to fine-tune the final resting position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX300-10 the Right Cylinder?
Select this 200 mm bore variant when your application requires extreme force, as it provides 21991N of push force at 0.7 MPa, dwarfing the 14074N available from the smaller 160 mm bore. The 10 mm adjustment range is highly valuable for dialing in exact end-stops during machine setup or product changeover, avoiding the need to physically swap out a fixed-stroke SAI cylinder.
Because the nominal stroke is 300 mm, an external guide is recommended to prevent excessive side-loading on the rod. Remember that the rear adjuster acts only as a travel stop; it does not hold the load if air pressure drops. For true load-holding without live pressure, consider an external rod lock or the AirTAC SAIL series. This model is dimensionally interchangeable per ISO 15552.
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 SAIJ200AX300-10 FAQ
At 0.5 MPa it provides 15708N push and 15080N pull. At 0.9 MPa, the push force increases to 28274N. The maximum thrust at 1.0 MPa is 3204 kgf.
The rear adjuster acts as a mechanical stop that shortens the retract stroke by up to 10 mm. This gives you an adjustable travel window of 290 to 300 mm. It only sets the end-position; it does not lock the load without live air pressure.
