About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-40S
The AirTAC SAIJ80X60-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 60 mm travel by up to 40 mm. This yields a usable stroke window of 20 to 60 mm, giving you exact end-position control at commissioning without adding external stops or swapping the unit.
This variant features an SUS420J2 stainless steel rod for enhanced corrosion resistance, PT tapered port threads, and a built-in magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets found on some standard cylinders.

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 SAIJ80AX60-40S Is Used
Machine Changeovers
Quickly fine-tune the travel end-position from 20 to 60 mm during product size transitions on a packaging line without replacing the cylinder.
Adjustable Pressing
Dial in the exact clamping depth for assembly operations, using the 4523 N of available force at 0.9 MPa to seat components accurately.
Sensor-Ready Positioning
Leverage the integrated magnet and dual sensor grooves to mount CMSE or DMSE switches for precise end-of-stroke detection in automated stations.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-40S the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers, replacing the need to stock multiple fixed-stroke SAI cylinders. When matching an ISO 15552 replacement, align the 80 mm bore, 60 mm nominal stroke, 40 mm adjustment, G3/8 port, and the -S magnet requirement.
Because the rear adjuster acts purely as a mechanical stop and the air cushions handle deceleration, neither will hold a load without live air pressure. If your fixture requires fail-safe load holding, consider an external rod lock, a pilot-operated check valve, or AirTAC SAIL and BSAI locking cylinders instead.

- ✓ 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 SAIJ80AX60-40S FAQ
At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster screw mechanically limits the piston's retraction, allowing you to shorten the effective stroke by up to 40 mm. This creates a usable travel window of 20 to 60 mm, which can be fine-tuned during commissioning without changing the cylinder.
