About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX170-50
The AirTAC SAIJ80X170-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 120 to 170 mm without adding external stops. Delivering 2268N of pull force at 0.5 MPa, it provides substantial thrust for mid-weight handling tasks.
This variant uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready for AirTAC CMSE reed or DMSE electronic sensors if position feedback is later required.

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 SAIJ80AX170-50 Is Used
Machine Changeover
Dial in the 120-170mm travel window during product size transitions on packaging lines without replacing hardware.
End-Stop Tuning
Use the 50mm rear adjuster to precisely set the retract end-position during commissioning, absorbing mechanical tolerance variations.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX170-50 the Right Cylinder?
Choose this 80mm bore model when an application requires 2268N of pull force at 0.5 MPa, stepping up from the 50mm bore which provides 825N. The 50mm adjustment range is ideal for machines processing multiple product sizes, allowing rapid end-position changes at commissioning without swapping the cylinder. Note that the rear adjuster is a travel stop, not a lock; the SAIJ does not hold loads without live air, so explore SAIL or BSAI variants if dead-load holding is required.
When replacing an ISO 15552 cylinder, match the 80mm bore, 170mm stroke, PT port threads, and the chosen mounting set (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Although the 25mm rod and M20x1.5 thread handle high side loads, an external guide is recommended for this 170mm stroke to prevent rod wear.
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 SAIJ80AX170-50 FAQ
The rear adjuster acts as an external stopper that shortens the effective stroke by up to 50mm, giving a usable travel window of 120 to 170mm. It decelerates the travel end but does not lock or hold the load without live air pressure.
It can deliver up to 513 kgf at its maximum 1.0 MPa pressure rating.
