About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-75S
The AirTAC SAIJ200X180-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers massive thrust, pushing 15708N and pulling 15080N at 0.5 MPa. By turning the rear screw, you can trim the nominal 180mm stroke back by up to 75mm, creating a precise 105-180mm usable travel window for product changeovers. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for CMSE reed or DMSE electronic switches.
This model uses a SUS420J2 stainless steel rod (option A) for superior corrosion resistance compared to standard carbon steel. Fluid connections use PT tapered G3/4 ports. The rear adjuster acts purely as a mechanical stop to set the retract end position; it does not lock or hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-75S Is Used
Heavy Press Tuning
Fine-tune the 105-180mm travel window during machine setup to precisely position heavy pressing or forming tools without mechanical shims.
Variable Product Changeover
Dial in the retract end-stop on the fly when switching between large product sizes on a conveyor line, saving changeover time.
Automated Heavy Clamping
Secure massive workpieces using 15708N of push force at 0.5 MPa, adjusting the clamping depth perfectly to the material batch.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-75S the Right Cylinder?
Choose this 200mm bore when your application demands extreme force, offering up to 3204 kgf at 1.0 MPa. If you do not need this capacity, stepping down to a 160mm bore yields 10053N push force at 0.5 MPa, which may better suit medium-heavy handling. The adjustable stroke is ideal for commissioning fine-tune adjustments or variable end-stops without swapping cylinders or adding external stops. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
When replacing an ISO 15552 cylinder, match the 200mm bore, 180mm stroke, 75mm adjustment, PT G3/4 ports, and the -S magnet. Although the 40mm rod and M36x2 thread handle high side loads, an 180mm stroke still requires an external guide to prevent binding under heavy loads. Operating speed ranges from 30-500 mm/s, controlled by variable air cushions at both ends.
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 SAIJ200AX180-75S FAQ
At 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At its maximum 1.0 MPa operating pressure, it delivers up to 3204 kgf.
A rear screw stopper lets you mechanically shorten the 180mm nominal stroke by up to 75mm, providing a usable travel window of 105-180mm. This allows precise end-position tuning at commissioning without replacing the cylinder.
