About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-20S
The AirTAC SAIJ200X95-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a substantial 15708N push force at 0.5 MPa and uses a PT tapered G3/4 port. The integrated -20 mm adjustment screw allows you to fine-tune the effective travel window down to 75-95 mm during commissioning without adding external stops.
This unit includes a -S magnet for position sensing with AirTAC CMSE reed and DMSE electronic switches. The piston rod is built from SUS420J2 stainless steel for enhanced corrosion resistance. It supports the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and runs at 30-500 mm/s, omitting FB, CA, CB and CR options.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-20S Is Used
Heavy Pressing
Delivers 15708N of push force for assembly presses, with the 75-95 mm travel window allowing precise bottoming-out height adjustments.
Line Changeover
Quickly reconfigure end-stops for varying product sizes on a conveyor line by turning the rear adjuster instead of physically swapping cylinders.
Automated Forming
Handles high-force forming operations, using the rear stop to tune the material compression depth accurately during machine setup.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX95-20S the Right Cylinder?
Choose this 200 mm bore when your application requires maximum thrust up to 15708N at 0.5 MPa, stepping up from the 160 mm bore which yields 10053N. The adjustable 75-95 mm travel window is perfect for product changeovers on a line, letting you dial in the exact end-position rather than swapping a fixed-stroke SAI cylinder. The rear adjuster acts strictly as a travel stop to set the end-position, not as a lock; it will not hold the load without live air pressure. For true fail-safe load holding, consider the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 95 mm nominal stroke, 20 mm adjustment, PT G3/4 port, and -S magnet. Because the 95 mm stroke is relatively short for this massive bore, side-loading is minimal, but you should still ensure the load is guided to prevent binding. The SUS420J2 rod material offers better moisture resistance than standard carbon steel.
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 SAIJ200AX95-20S FAQ
The -20 code means the rear adjuster screw can shorten the 95 mm nominal stroke by up to 20 mm. This gives you an effective usable travel window of 75-95 mm, allowing you to fine-tune the retract end-position at commissioning.
At 0.5 MPa operating pressure, it provides 15708N of push force and 15080N of pull force. It can deliver up to 21991N push force at 0.7 MPa, with a maximum operating pressure of 1.0 MPa.
