About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX80-30S
The AirTAC SAIJ32X80-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the nominal 80 mm travel by up to 30 mm, creating a precise 50-80 mm usable window. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet supports position detection.
This SKU uses a SUS420J2 stainless steel rod (option A) for corrosion resistance and pairs with PT tapered port threads. The rear adjuster acts purely as a mechanical stop to dial in end positions during commissioning; it does not lock the load without live air pressure. For speed, the bore operates within a 30-800 mm/s range, while the variable air cushions at both ends manage end-of-stroke deceleration.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX80-30S Is Used
End-Position Tuning
Dial in the exact retract distance within a 50-80 mm window during machine commissioning without swapping hardware.
Product Changeover
Quickly adapt the cylinder stroke on packaging lines handling varying container sizes by adjusting the rear stopper.
Light Assembly
Apply up to 402 N of push force at 0.5 MPa for precise, repeatable pressing and clamping operations.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX80-30S the Right Cylinder?
Choose this 32 mm bore when 402 N of thrust at 0.5 MPa is sufficient, stepping up to the 40 mm bore (628 N) if your payload increases. An adjustable stroke is selected over a fixed SAI cylinder when you need to fine-tune the retract end-point during machine setup or product changeovers without adding external stops. Because the stroke is under 300 mm, side-load concerns are minimal, but always guide long unsupported loads. To match this ISO 15552 cylinder, specify the 32 mm bore, 80 mm stroke, 30 mm adjustment, PT G1/8 port, and the -S magnet for CMSE or DMSE sensors. Note that SAIJ supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR. If you need to hold the load without live air, use a SAIL or BSAI cylinder instead.

- ✓ 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 SAIJ32AX80-30S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
The rear mechanical stopper allows you to shorten the nominal 80 mm stroke by up to 30 mm, providing an adjustable travel window of 50 to 80 mm. This stopper sets the end position but does not lock the load without continuous air pressure.
