About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX175-40S
The AirTAC SAIJ80X175-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. The built-in adjuster allows you to trim the 175mm nominal stroke back by up to 40mm, creating a precise 135-175mm usable travel window for fine-tuning end positions during commissioning.
This variant includes a magnet for CMSE and DMSE sensors and uses a SUS420J2 stainless steel rod for enhanced corrosion resistance. The extruded aluminum barrel incorporates 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.

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 SAIJ80AX175-40S Is Used
Machine Changeover
Dial in the 135-175mm travel window during product size changes without swapping the cylinder or bolting on external stops.
End-Position Tuning
Fine-tune the retract end position at commissioning to absorb mechanical tolerances and ensure precise tooling contact.
Variable Stops
Set different retract lengths on the fly for assembly lines handling multiple product variants on the same fixture.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX175-40S the Right Cylinder?
If your setup needs less force, stepping down to a 63mm bore yields 2805N, while moving up to a 100mm bore provides 7068N. The adjustable stroke is chosen over a fixed SAI cylinder to allow product changeovers and end-position tuning without physically swapping the cylinder or adding external stops.
For ISO 15552 replacement matching, ensure you specify the 80mm bore, 175mm stroke, 40mm adjustment range, PT tapered ports, and the -S magnet option. Because the nominal stroke is under 300mm, side-load risks are moderate, but the 25mm rod and M20x1.5 thread handle higher off-center loads well. Remember that the rear adjuster is a travel stop, not a lock; it cannot hold loads without live air, so use a SAIL or BSAI cylinder if fail-safe holding is required.
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 SAIJ80AX175-40S FAQ
It operates at speeds between 30 and 800 mm/s.
A rear adjuster screw acts as a mechanical stop, allowing you to shorten the 175mm nominal stroke by up to 40mm. This provides a usable travel window of 135 to 175mm for fine-tuning the end position without replacing the cylinder.
