About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX190-20S
The AirTAC SAIJ80X190-20-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 170-190 mm usable travel window, letting you dial back the nominal 190 mm stroke by up to 20 mm during commissioning without adding external stops.
This variant uses an SUS420J2 stainless steel piston rod for enhanced corrosion resistance and ships with a position-sensing magnet (-S) for use with AirTAC CMSE reed and DMSE solid-state sensors. The extruded aluminum barrel includes sensor grooves on both sides. It uses PT tapered ports (G3/8) and supports a speed range of 30-800 mm/s.

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 SAIJ80AX190-20S Is Used
End-Position Tuning
Dial in the exact 170-190 mm retract distance during machine setup to accommodate varying material thicknesses without swapping cylinders.
Product Changeover
Quickly adjust the stroke stop on a packaging line when switching to a different package size, using the rear screw to set the new travel endpoint.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX190-20S the Right Cylinder?
The adjustable stroke is ideal for machine changeovers or fine-tuning end positions, whereas a fixed-stroke SAI cylinder locks you to a single travel length. Remember that the rear adjuster is a travel stop, not a lock; it cannot hold the load without live air. For fail-safe load holding, consider an SAIL or BSAI cylinder.
This SAIJ80X190-20-S is dimensionally interchangeable per ISO 15552. It supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. The 25 mm rod and M20x1.5 thread handle high side loads, but even with a robust rod, strokes approaching 300 mm require an external guide to prevent rod binding.
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 SAIJ80AX190-20S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from the nominal 190 mm down to 170 mm. It sets the travel end and works with the air cushion to decelerate the piston, but it is not a lock and will not hold the load without live air pressure.
At 0.9 MPa, the push force increases to 4523 N. The maximum operating pressure is 1.0 MPa.
