About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX195-30
The AirTAC SAIJ200X195-30 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 165-195 mm usable travel window by allowing you to dial back the 195 mm nominal stroke by up to 30 mm. Belonging to the highest force class, it delivers 21991 N of push force at 0.7 MPa, making it suitable for heavy-duty press and clamp operations.
This unit features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance over standard carbon steel. The barrel is an extruded aluminum profile with sensor grooves on both sides, and the PT tapered port threads ensure a robust, sealed connection in demanding pneumatic setups.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX195-30 Is Used
Heavy Press Tuning
Dial in the exact 165-195 mm end-stop during machine setup to accommodate varying material thicknesses in heavy pressing tasks.
Product Changeover
Quickly adjust the retract position on automated lines when switching between product sizes, avoiding the need to install external mechanical stops.
Clamp Positioning
Fine-tune the clamping reach on large fixtures, ensuring precise contact without over-traveling or stressing the workpiece.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX195-30 the Right Cylinder?
Choose this 200 mm bore model when an application demands massive thrust that a 160 mm bore cannot provide, stepping up from the 14074 N push force at 0.7 MPa of the smaller neighbor. An adjustable stroke is selected over a fixed SAI cylinder when you need fine end-position tuning during commissioning or product changeover without swapping the physical cylinder or adding external stops. The rear adjuster acts solely as a travel stop to decelerate the load, not as a lock; for true load-holding without live air pressure, use an external rod lock or pilot-operated check valve. Because the stroke is under 300 mm, side-load risks are lower, but the heavy 40 mm rod and M36x2 thread still handle substantial forces effectively.
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 SAIJ200AX195-30 FAQ
At an operating pressure of 0.7 MPa, the 200 mm bore provides a push force of 21991 N and a pull force of 15080 N. It can reach up to 28274 N push force at 0.9 MPa.
The rear adjuster screw lets you shorten the 195 mm nominal stroke by up to 30 mm, creating a 165-195 mm usable travel window. This allows for precise end-position tuning at commissioning without replacing the cylinder.
