About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-75
The AirTAC SAIJ200X750-75 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty motion control, featuring a 200mm bore and a 750mm stroke. An integrated rear stopper mechanism allows you to mechanically shorten the effective travel by up to 75mm, creating a highly flexible 675 to 750mm usable window. This built-in adjustability eliminates the need to swap out the entire actuator or bolt on external stopper blocks when refining end positions during machine commissioning or product changeovers. Delivering immense thrust, it generates 21991N of push force and 15080N of pull force at a 0.7MPa operating pressure.
Built to withstand demanding industrial environments, this variant incorporates a SUS420J2 stainless steel piston rod for superior corrosion resistance and durability. The extruded aluminum barrel features sensor grooves on both sides for straightforward position feedback. While the adjustable stopper and integrated air cushions effectively decelerate the load at the travel ends, this unit does not hold position without live air pressure. For fail-safe load holding, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-75 Is Used
Heavy Pressing Operations
Ideal for large-scale stamping or forming stations where the 675-750mm stroke window allows operators to fine-tune the bottom-dead-center pressing position without reworking the machine base.
Product Changeover
Perfectly suited for automated lines running multiple product sizes, where the 75mm rear adjustment quickly adapts the cylinder's extend position to new part dimensions on the fly.
Large Assembly Jigs
Provides the immense 21991N push force required to seat heavy industrial components, with adjustable travel to accommodate various assembly heights and tooling clearances.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-75 the Right Cylinder?
Selecting this 200mm bore actuator provides a maximum thrust of 28274N at 1.0MPa, making it ideal for high-force pressing, lifting, and clamping tasks. If your application requires less force, stepping down to a 160mm bore yields 14074N of push at 0.7MPa, which may offer a more compact and economical footprint. The defining advantage of the SAIJ200X750-75 is its 75mm adjustment range, which allows operators to dial in exact end-of-stroke positions without relying on external mechanical stops. It supports a reduced set of ISO 15552 mounting interfaces, including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. The fluid porting utilizes a PT tapered G3/4 thread.
Because this model features a long 750mm stroke, the 40mm diameter piston rod is highly susceptible to side-loading and sagging if the load is not fully supported. An external guide rail system must be used to prevent binding and premature seal wear. Furthermore, the operational speed is rated for 30-500mm/s, which is lower than smaller bores, ensuring safe kinetic energy management for this massive actuator. The rear adjuster acts purely as a travel stop and does not function as a lock.

- ✓ 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 SAIJ200AX750-75 FAQ
The cylinder has a rear adjusting screw that acts as a mechanical stopper, allowing you to shorten the nominal 750mm stroke by up to 75mm. This creates a usable travel window of 675 to 750mm, enabling fine-tuning of the end position during setup without adding external stops.
At the maximum operating pressure of 1.0MPa, this cylinder generates a maximum push force of 28274N. At a standard 0.7MPa, it provides a push force of 21991N and a pull force of 15080N.
