About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX70-10
The AirTAC SAIJ200X70-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers immense thrust, pushing with 15708N and pulling with 15080N at 0.5MPa, making it suited for heavy-duty press operations. The built-in adjustment screw allows you to fine-tune the end position, providing a usable travel window of 60-70mm for precise machine setup.
This model features a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. It operates at speeds of 30-500mm/s and includes variable air cushions at both ends to manage kinetic energy. The extruded aluminum barrel integrates sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic sensors if a magnet is added later.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX70-10 Is Used
Heavy Press Tuning
Dial in the exact 60-70mm travel window during heavy press commissioning to accommodate material thickness variations without swapping cylinders.
Product Changeover
Quickly adjust the retract end-position by up to 10mm on automated lines when switching between different product sizes or stack heights.
Short-Stroke Clamping
Utilize the massive 15708N push force at 0.5MPa for heavy-duty clamping tasks where a short, adjustable stroke is required for precise gripping.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX70-10 the Right Cylinder?
Select this 200mm bore cylinder when your application requires massive force, such as 15708N of push thrust at 0.5MPa, but demands a short, highly tunable travel distance. The 10mm rear adjuster is ideal for dialing in exact end-stops during product changeovers without adding external physical stops. If you need a longer fixed stroke without adjustment, the standard SAI series is the alternative.
Because the 70mm nominal stroke is short, side-load risks are minimal, but always ensure the load is guided externally. Remember that the rear adjuster functions only as a travel stop and does not hold the load without live air pressure; for true fail-safe load holding, consider the SAIL or BSAI series. This unit is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ200AX70-10 FAQ
At 0.5MPa operating pressure, this 200mm bore cylinder provides a push force of 15708N and a pull force of 15080N. It can reach a maximum push force of 3204 kgf at 1.0MPa.
The nominal stroke is 70mm, but the rear adjuster screw allows you to shorten the effective travel by up to 10mm. This creates a usable stroke window of 60-70mm, enabling fine-tuning of the end position during setup.
