About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX850-10S
The AirTAC SAIJ32X850-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear mechanical stroke adjuster. It delivers 563N of push force at 0.7 MPa and provides a usable travel window of 840-850 mm, allowing you to trim the effective stroke by up to 10 mm during commissioning without swapping the unit.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for use with CMSE reed or DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the PT tapered port threads match the standard G1/8 fitting size for this bore.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX850-10S Is Used
End-Stop Calibration
Dial in the exact 840-850mm retraction point during machine setup to compensate for mechanical tolerance without adding external stopper blocks.
Product Changeover
Quickly adjust the end-of-stroke position on a packaging line when handling different carton lengths, using the 10mm trim to fine-tune the motion.
Sensor Targeting
Leverage the integrated magnet with DMSE electronic sensors to confirm the adjusted position, ensuring the long 850mm travel completes accurately.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX850-10S the Right Cylinder?
Choose this 32mm bore when an application requires precise end-position tuning; if you need more thrust, stepping up to the 40mm bore yields 879N push force at 0.5 MPa. The 10mm rear adjuster acts purely as a travel stop for fine-tuning product changeovers, not as a load-holding brake. For position holding without live air pressure, consider an external rod lock or the AirTAC SAIL locking cylinder. To replace an ISO 15552 cylinder, match the 32mm bore, 850mm stroke, 10mm adjustment, PT port, and -S magnet.
Because the 850mm stroke is long relative to the 12mm rod diameter, it is critical to use an external guide to prevent excessive side-loading and rod bending. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32AX850-10S FAQ
At 0.7 MPa operating pressure, this 32mm bore cylinder provides 563N of push force and 483N of pull force. The maximum push force is 724N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 850mm nominal stroke by up to 10mm, creating an effective travel window of 840-850mm. It does not lock the load without live air pressure.
