About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-50
The AirTAC SAIJ80X95-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The extruded aluminum barrel includes sensor grooves on both sides for straightforward detection mounting.
This unit is built with an SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads with a G3/8 connection. The rear adjustment screw acts purely as a mechanical stop to set the end-of-stroke position and relies on the variable air cushion for deceleration; it does not lock or hold the load without continuous live air pressure.

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 SAIJ80AX95-50 Is Used
Variable End-Stop Positioning
Ideal for assembly stations that process multiple product heights, allowing operators to fine-tune the 45-95mm retract distance quickly without changing the cylinder.
Machine Changeover Setup
Perfect for packaging lines requiring rapid format changes, where the rear stopper precisely sets the new end position to accommodate different package dimensions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX95-50 the Right Cylinder?
If your setup needs less force, stepping down to a 63mm bore yields 1559N; if you need significantly more clamping power, a 100mm bore provides 3927N. Because the nominal stroke is 95mm, side-loading is minimal, but always ensure the M20x1.5 rod thread is properly aligned with your external guide to prevent binding.
An adjustable stroke is chosen over a fixed SAI cylinder when machinery processes varying part sizes and needs a variable end-stop rather than manufacturing custom length units. To match this exact ISO 15552 replacement, specify an 80mm bore, 95mm stroke, 50mm adjustment range, PT G3/8 port, and SUS420J2 rod material. Note that for true load-holding without air pressure, you must integrate an external rod lock or choose an AirTAC SAIL or BSAI variant, as the adjuster here is not a brake. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ80AX95-50 FAQ
If operated at 0.7MPa, the push force increases to 3518N.
The rear adjuster screw allows you to mechanically shorten the nominal 95mm stroke by up to 50mm, creating a usable travel window of 45 to 95mm. The screw functions as a travel stop and relies on the air cushion for deceleration; it does not hold the load without live air.
