About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX50-40
The AirTAC SAIJ100X50-40 is a double-acting ISO 15552 profile cylinder engineered with a rear mechanical stopper, enabling you to trim the effective stroke by up to 40 mm. This yields a highly flexible 10-50 mm usable travel window, allowing precise end-position calibration at commissioning without external shims.
The piston features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance, paired with PT tapered port threads. Adjustment is handled by a rear screw that acts purely as a travel stop to set deceleration points; it is not a locking mechanism and cannot hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

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 SAIJ100AX50-40 Is Used
End-Stop Calibration
Dial in the exact 10-50 mm travel distance during machine commissioning to perfect positioning without machining external stoppers.
Product Changeover
Rapidly adjust the stroke end-point on packaging lines when switching between different product sizes or formats.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX50-40 the Right Cylinder?
Choose this 100 mm bore when your application demands high force that smaller bores cannot provide; for context, dropping to an 80 mm bore reduces push force to 2513 N at 0.5 MPa, while a 125 mm bore increases it to 6136 N. The adjustable stroke is ideal for machine setups requiring variable end-stops or frequent product-size changeovers, bypassing the need to physically swap out a fixed-stroke SAI cylinder. To ensure a valid ISO 15552 replacement match, verify the 100 mm bore, 50 mm nominal stroke, 40 mm adjustment range, PT G1/2 port, and the specific mounting accessory (Basic, FA, LB, TC, FTC, TCM1, or 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 SAIJ100 Adjustable Cylinder SAIJ100AX50-40 FAQ
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the 50 mm nominal stroke by up to 40 mm. This creates a usable travel window of 10 to 50 mm, which can be fine-tuned during setup.
At 0.9 MPa, the push force increases to 7068 N.
