About the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX80-10
The AirTAC SAIJ40X80-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 80 mm travel that can be fine-tuned down by up to 10 mm, creating a precise 70-80 mm usable window to dial in retract end positions without external stops.
This variant is equipped with an SUS420J2 stainless steel rod (material code A) for improved corrosion resistance compared to standard carbon steel. It uses PT tapered port threads (G1/4) and lacks a piston magnet, meaning it requires external limit switches rather than embedded CMSE or DMSE sensors. The extruded aluminum barrel ensures rigid mounting while remaining dimensionally interchangeable with ISO 15552 cylinders.

Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 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 SAIJ40 Adjustable Cylinder SAIJ40AX80-10 Is Used
Machine Commissioning
Dial in the exact 70-80 mm retract position during initial machine setup without machining new hard stops.
Product Changeover
Quickly adjust the end-of-stroke position by up to 10 mm when running a slightly different product size on the line.
Assembly Clamping
Provides 628 N of clamping force at 0.5 MPa with a finely tuned retraction point to prevent over-travel.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40AX80-10 the Right Cylinder?
The 10 mm adjustment range is ideal for machine setups requiring minor end-position tweaks during commissioning, avoiding the need to physically swap out a fixed-stroke SAI cylinder. Remember that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for dead-air load holding, consider an AirTAC SAIL or BSAI cylinder.
When replacing an ISO 15552 cylinder, verify the 40 mm bore, 80 mm stroke, 10 mm adjustment range, PT port threads, and the absence of a magnet. Because the stroke is under 300 mm, side-load stress on the 16 mm rod is minimal, though external guiding remains recommended for heavy lateral loads. The mounting hardware is compatible with Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.
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 SAIJ40 Adjustable Cylinder SAIJ40AX80-10 FAQ
At 0.7 MPa, the push force increases to 879 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 80 mm nominal stroke by up to 10 mm. This creates a 70-80 mm travel window for fine-tuning the end position without replacing the cylinder.
