Airtac Adjustable Cylinder SAIJ32 SAIJ32AX140-100S
The AirTAC Adjustable Cylinder SAIJ32 SAIJ32AX140-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 140mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX140-100S
Its 140 mm nominal stroke can be dialed back by up to 100 mm, creating a wide 40-140 mm usable travel window for highly variable end-position tuning. This makes it ideal for equipment that requires frequent product-size changeovers without swapping hardware.
Equipped with a SUS420J2 stainless steel rod (option A) and PT tapered ports, this unit resists corrosion better than standard carbon steel. The integrated magnet (-S) supports position sensing via AirTAC CMSE reed or DMSE solid-state switches mounted in the dual-side sensor grooves. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX140-100S Is Used
Machine Changeover
Dial in the 40-140 mm travel window to accommodate different product lengths on the same conveyor line without adding external stops.
End-Position Tuning
Fine-tune the retract stroke during commissioning to prevent crashing into hard stops, protecting tooling and ensuring precise placement.
Sensor-Driven Testing
Leverage the internal magnet with DMSE solid-state sensors to verify position across the adjusted travel range in automated test fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX140-100S the Right Cylinder?
An adjustable stroke is selected over a fixed SAI when you need on-site fine-tuning of the end position during commissioning. For any application exceeding 300 mm of stroke, an external guide is recommended to manage side loads, though this 140 mm unit handles standard loads well.
To match this ISO 15552 replacement exactly, specify: 32 mm bore, 140 mm stroke, 100 mm adjustment range, PT port thread, and the -S magnet. Remember that the rear adjuster is a stop, not a lock; for load-holding without live air, consider the SAIL or BSAI series. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 Adjustable Cylinder SAIJ32 SAIJ32AX140-100S FAQ
The rear adjuster screw lets you shorten the 140 mm nominal stroke by up to 100 mm, creating a 40-140 mm usable travel window. The adjuster acts as a physical stop to set the end position and does not lock the load without air pressure.
