Airtac SAIJ80 Adjustable Cylinder SAIJ80AX190-30S
The AirTAC SAIJ80 Adjustable Cylinder SAIJ80AX190-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 190mm stroke, G3/8 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 SAIJ80 Adjustable Cylinder SAIJ80AX190-30S
The AirTAC SAIJ80X190-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 160 to 190 mm. The barrel features an extruded aluminum design with sensor grooves on both sides, and the included magnet enables precise tracking via CMSE reed or DMSE solid-state switches.
This model features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and uses a PT tapered port thread. The rear adjuster acts purely as a mechanical stop to fine-tune end positions at commissioning; it does not hold the load without live air pressure. For applications requiring true load-holding, consider the SAIL or BSAI series instead.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80AX190-30S Is Used
Machine Changeover
Dial in the exact 160-190mm travel needed when switching product sizes on a packaging line, using the rear adjuster instead of repositioning physical hard stops.
End-Position Tuning
Fine-tune the retract stroke during initial commissioning to perfectly seat a heavy 80mm-bore tooling head without adding external spacers.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX190-30S the Right Cylinder?
Choose this 80mm bore when you need more thrust than a 63mm cylinder provides (2182N at 0.7 MPa) but want to avoid the larger footprint of a 100mm unit. The 30mm adjustment range is ideal for product changeovers, allowing you to dial in the exact end-of-stroke position without swapping the cylinder or adding external stops. Unlike a fixed-stroke SAI cylinder, this adjustable variant simplifies machine setup.
When replacing an ISO 15552 cylinder, match the 80mm bore, 190mm nominal stroke, PT port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interfaces. Note that SAIJ omits the FB, CA, CB, and CR mountings. Since the 190mm stroke is under 300mm, side-load concerns are minimal, but the 25mm rod diameter handles standard lateral loads effectively.
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 SAIJ80 Adjustable Cylinder SAIJ80AX190-30S FAQ
The rear adjuster allows you to shorten the effective stroke by up to 30mm, creating a usable travel window of 160 to 190mm. The adjuster acts as a mechanical stop to fine-tune the retract position and does not function as a lock to hold the load without air pressure.
