About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX800-100S
The AirTAC SAIJ200X800-100-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications. It features an integrated rear adjusting screw that allows you to fine-tune the effective stroke length within a 700-800 mm usable travel window. This enables precise end-position calibration at commissioning without the need to physically swap out the cylinder or bolt on external stops. Delivering immense thrust, it provides 21991N of push force and 15080N of pull force at 0.7 MPa.
This specific SKU is configured with an SUS420J2 stainless steel rod (code A) for superior corrosion resistance and includes a built-in magnet for position sensing. It is fully compatible with AirTAC CMSE reed switches and DMSE solid-state electronic sensors, which mount cleanly into the dual-sided sensor grooves on the extruded aluminum barrel. The cylinder uses PT tapered ports sized at G3/4 and operates at speeds between 30-500 mm/s.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX800-100S Is Used
Heavy Press Fine-Tuning
Dial in the exact 700-800 mm travel end-point during press commissioning to accommodate varying material thicknesses without adding external mechanical stops.
Multi-Product Line Changeover
Quickly adjust the retract stroke limit on a 200 mm bore actuator when switching a production line between different large-scale product dimensions.
Large Assembly Calibration
Set precise end-of-stroke positioning for heavy assembly stations, using the rear screw to absorb energy alongside the standard 50 mm air cushions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX800-100S the Right Cylinder?
Choose this 200 mm bore actuator when your application demands maximum pneumatic force that smaller bores cannot provide, such as when stepping up from a 160 mm bore that yields 14074N push force at 0.7 MPa. The 100 mm adjustable stroke is ideal for machinery that requires variable end-stops to accommodate multiple product sizes on a single line. Because the nominal 800 mm stroke is substantial, an external guide rail is strongly recommended to prevent excessive side-loading on the M36x2 piston rod, ensuring optimal seal and bearing life.
For load-holding requirements, remember that this SAIJ model is a standard double-acting cylinder. The rear adjuster acts purely as a mechanical travel stop to set deceleration and end-position, not as a lock. It will not hold a load vertically or resist forces without live air pressure. If true fail-safe load holding is required, consider the AirTAC SAIL pneumatic lock or BSAI clamp-lock series instead. This unit is dimensionally interchangeable per ISO 15552 and utilizes a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ200AX800-100S FAQ
At an operating pressure of 0.7 MPa, this 200 mm bore cylinder generates a push force of 21991N and a pull force of 15080N. The maximum push force is 28274N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm from the 800 mm nominal length, providing a usable travel window of 700-800 mm. It functions as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
