About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX195-75S
The AirTAC SAIJ200X195-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 28274N at 0.9 MPa. Its built-in 75mm adjustment screw allows you to dial back the 195mm nominal stroke, providing a precise 120-195mm usable travel window for commissioning without adding external stops. The robust 40mm piston rod and M36x2 rod thread handle high side loads, while the SUS420J2 stainless steel rod material adds corrosion resistance.
This model includes a magnet for CMSE and DMSE sensors, utilizing the dual-side sensor grooves on its extruded aluminum barrel. It features PT tapered port threads (G3/4) and variable air cushions at both ends to decelerate heavy loads. The rear adjuster acts strictly as a travel stop, meaning it will not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX195-75S Is Used
Heavy Press Tuning
Dial in the exact 120-195mm travel window for high-force pressing applications, ensuring precise end positions without swapping cylinders.
Product Changeover
Quickly adjust the retract stop during product size changes on a line, using the 75mm adjustment range to adapt to new dimensions.
Machine Setup
Fine-tune the end-of-stroke position at commissioning to clear mechanical interferences, relying on the 40mm rod for heavy side loads.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX195-75S the Right Cylinder?
Choose this 200mm bore cylinder when an application requires extreme force, such as 21991N push at 0.7 MPa, alongside variable end-position tuning. If your thrust requirements are lower, stepping down to a 160mm bore yields 14074N push at 0.7 MPa, which may reduce air consumption. The adjustable stroke is ideal for product changeovers on a line, allowing you to fine-tune the end-of-travel position quickly. Because the nominal stroke is 195mm, an external guide is recommended for long unsupported loads. For load-holding without live pressure, use a SAIL or BSAI cylinder instead of relying on the adjuster. This unit is dimensionally interchangeable with ISO 15552 cylinders, featuring a 195mm stroke, 75mm adjustment, PT G3/4 ports, and a magnet for CMSE/DMSE switches.

- ✓ 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 SAIJ200AX195-75S FAQ
At 0.9 MPa, the push force is 28274N and the pull force is 15080N. The maximum push force at 1.0 MPa is 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 195mm nominal stroke, providing a usable travel window of 120-195mm. It is a stop, not a lock, and will not hold the load without live air.
