Airtac SAIJ100 Adjustable Cylinder SAIJ100AX40-40
The AirTAC SAIJ100 Adjustable Cylinder SAIJ100AX40-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 40mm stroke, G1/2 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 SAIJ100 Adjustable Cylinder SAIJ100AX40-40
It features a SUS420J2 stainless steel rod and PT tapered port threads. The integrated adjustment mechanism allows the 40mm nominal stroke to be dialed back by up to 40mm, providing a 0-40mm usable travel window for exact end-position tuning.
This model utilizes an extruded aluminum barrel with sensor grooves on both sides, designed for use with AirTAC CMSE reed and DMSE electronic sensors. The rear adjuster acts purely as a travel stop to decelerate the piston, not as a lock, meaning it will not hold a load without live air pressure. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 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 SAIJ100 Adjustable Cylinder SAIJ100AX40-40 Is Used
Machine Setup Calibration
Fine-tune the 0-40mm travel window during machine commissioning to dial in exact positioning without adding external stops.
Product Changeover
Quickly adjust the end-stop position on a packaging line when switching to a different sized product, saving setup time.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX40-40 the Right Cylinder?
Choose this 100mm bore cylinder when your application requires substantial thrust (3927N at 0.5 MPa or 7068N at 0.9 MPa) alongside precise end-stop calibration at commissioning. The adjustable stroke is ideal for product changeovers where the end position varies slightly, eliminating the need to swap out a fixed-stroke SAI cylinder.
For load-holding requirements without continuous air pressure, this cylinder is insufficient as the rear adjuster is only a stop; consider the SAIL or BSAI series instead. Because the stroke is 40mm, side-load stress is minimal, but always ensure proper alignment. To replace an ISO 15552 cylinder, match the 100mm bore, 40mm stroke, 40mm adjustment, G1/2 port, and mounting hardware.
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 SAIJ100 Adjustable Cylinder SAIJ100AX40-40 FAQ
At 0.9 MPa, the push force increases to 7068N.
The rear adjuster acts as a mechanical stop that allows you to trim the 40mm nominal stroke back by up to 40mm, creating a 0-40mm usable travel window. It sets the end position but does not lock or hold the load without live air pressure.
