About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX20-10S
The AirTAC SAIJ200X20-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 10 to 20 mm, allowing you to dial back the 20 mm nominal stroke by up to 10 mm during commissioning without adding external stops. In the 200 mm bore class, it generates a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa, making it ideal for heavy-duty pressing and clamping.
This variant includes a magnet for position sensing and uses an SUS420J2 stainless steel rod for enhanced corrosion resistance. It features a PT tapered port thread and operates at speeds of 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed and DMSE electronic switches.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX20-10S Is Used
Heavy-Duty Short-Stroke Pressing
Delivers up to 15708 N of push force for high-impact stamping, riveting, and forming tasks within a tight 10 to 20 mm travel window.
Precision Clamping Setup
The 10 mm rear adjustment allows operators to fine-tune clamping depth on the fly without swapping out the cylinder or repositioning external stops.
Changeover Positioning
Ideal for machinery requiring frequent product size changes, letting technicians quickly dial in the exact end-of-stroke position during commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX20-10S the Right Cylinder?
Select this 200 mm bore model when an application requires extreme thrust within a very short linear footprint. If 15708 N of push force at 0.5 MPa exceeds your requirement, stepping down to the 160 mm bore yields 10053 N, which may better suit medium-heavy loads while saving space. The adjustable stroke is chosen over a fixed SAI cylinder when precise end-position tuning is needed for variable product sizes or machine changeover.
For any stroke of 300 mm or more, an external guide is recommended to handle side loads, though this 20 mm stroke is compact. Remember that the rear adjuster is a travel stop, not a lock; a plain SAIJ does not hold position without live air. For load-holding without pressure, consider the SAIL or BSAI series. This model is dimensionally interchangeable with ISO 15552 cylinders, configured with a PT port, SUS420J2 rod, and a magnet.

- ✓ 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 SAIJ200AX20-10S FAQ
It features a rear adjusting screw that acts as a mechanical stopper, allowing you to shorten the effective stroke by up to 10 mm. This creates a usable travel window of 10 to 20 mm, which can be fine-tuned during commissioning without replacing the cylinder.
At a 0.5 MPa operating pressure, the SAIJ200X20-10-S provides a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
