About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX55-10S
The AirTAC SAIJ200X55-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 45 to 55 mm. Delivering massive thrust, it pushes with 15708 N and pulls with 15080 N at 0.5 MPa. This bore features a robust 40 mm carbon steel rod and M36x2 thread, while this specific SKU uses a SUS420J2 stainless steel rod (code A) for improved corrosion resistance.
It includes a -S magnet for position sensing, operating seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches mounted in the dual-side sensor grooves. The rear adjustment screw lets you fine-tune the retract end-position during commissioning without adding external stops, while the PT tapered ports ensure a tight, reliable pneumatic connection.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX55-10S Is Used
Heavy Press Fine-Tuning
Dial in the exact 45-55 mm retract position on heavy pressing tasks without swapping cylinders or adding external mechanical stops.
Product Changeover
Adjust the end-stop by up to 10 mm on the fly to accommodate minor variations in product sizes on the line.
Machine Commissioning
Set precise end positions during initial machine build using the rear screw, ensuring perfect alignment before full production runs.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX55-10S the Right Cylinder?
Choose this 200 mm bore when you need extreme force—up to 15708 N at 0.5 MPa—and a compact 55 mm travel. If your application requires less thrust, stepping down to a 160 mm bore yields 10053 N, whereas moving up is impossible as 200 mm is the largest standard size. The 10 mm adjustment range is ideal for dialing in exact end stops during machine setup or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder.
Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. Because this is a profile cylinder, it uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR. It is dimensionally interchangeable per ISO 15552.
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 SAIJ200AX55-10S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. The maximum push force is 28274 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm, giving a usable travel window of 45 to 55 mm. This stopper fine-tunes the end position but does not lock or hold the load without live air pressure.
