About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX115-100
The AirTAC SAIJ100X115-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits precise end-position tuning without swapping the unit. It provides a usable travel window of 15-115 mm, allowing you to dial back the 115 mm nominal stroke by up to 100 mm during commissioning or product changeover.
The rear adjuster functions strictly as a travel stop to set deceleration, not as a load lock; for position holding without live air pressure, consider the SAIL or BSAI series. This model features an extruded aluminum barrel with sensor grooves on both sides. Mounting options include the reduced SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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 SAIJ100AX115-100 Is Used
Variable End Stop Tuning
Dial in the exact clamping position on a fixture across a 15-115 mm window during machine setup, using the rear screw to fine-tune the travel end without external shims.
Product Size Changeover
Quickly adapt a packaging line to different carton heights by adjusting the stroke up to 100 mm, avoiding the need to physically swap out the entire pneumatic cylinder.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX115-100 the Right Cylinder?
The 100 mm adjustment range on this specific SKU is highly advantageous for machines requiring frequent product-size changeovers, allowing the end stop to shift across a 100 mm window without installing external mechanical stops.
Because the 115 mm nominal stroke is relatively short, side-loading is less of a concern here, but the 25 mm rod and M20x1.5 thread handle high axial loads well. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with ISO 15552 cylinders such as SMC or Festo equivalents. To match this configuration exactly, specify bore 100, stroke 115, 100 mm adjustment, PT ports, and no magnet.
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 SAIJ100AX115-100 FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjusting screw acts as a mechanical stop that allows you to shorten the effective stroke by up to 100 mm. This creates a usable travel window of 15-115 mm from the 115 mm nominal stroke, enabling fine-tuning at commissioning without replacing the cylinder.
