About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-10S
The AirTAC SAIJ200X180-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 170-180 mm. Delivering 15708 N of push force at 0.5 MPa, this massive bore handles heavy-duty positioning. The integrated -S magnet pairs directly with AirTAC CMSE reed and DMSE electronic sensors housed in the dual-sided extruded aluminum barrel grooves.
This configuration features a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and utilizes PT tapered ports. The 10 mm adjustment screw allows precise end-position tuning at commissioning without adding external stops. Note that this rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-10S Is Used
Heavy Press Tuning
Dial in the exact 170-180 mm retract position on heavy pressing or forming equipment during initial commissioning without external shims.
Product Changeover
Quickly adjust the end-stop by up to 10 mm on automated lines when transitioning between slightly different product sizes.
High-Force Positioning
Leverage the 15708 N push force at 0.5 MPa to move and position massive industrial fixtures with precise end-point control.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-10S the Right Cylinder?
Select this 200 mm bore when an application demands extreme thrust—stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N. The 10 mm adjustable window is ideal for fine-tuning the retract end during machine setup or product changeover, avoiding the need to physically swap a fixed-stroke SAI cylinder. For exact ISO 15552 replacement matching, verify the 180 mm stroke, 10 mm adjustment, PT port thread, and -S magnet requirement.
With a 180 mm stroke, the robust 40 mm rod and M36x2 thread provide substantial rigidity, but any long unsupported load still requires an external guide to prevent side-loading damage. Because the SAIJ adjuster and air cushions only decelerate travel, load-holding without live air requires a SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock.
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 SAIJ200AX180-10S FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster screw allows you to trim the effective stroke back by up to 10 mm, creating a 170-180 mm travel window. It functions as a mechanical stop for end-position tuning and is not a lock.
