About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X195-10S
The AirTAC SAIJ125X195-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to fine-tune the retract end-position by up to 10 mm. This yields a usable travel window of 185-195 mm, letting you dial in the exact stop without swapping out the barrel or bolting on external stops.
This variant includes a standard carbon steel piston rod and a magnetic piston (-S) for use with AirTAC CMSE reed and DMSE electronic solid-state sensors, which seat neatly into the dual-side sensor grooves on the extruded aluminum barrel. The rear adjuster functions purely as a mechanical travel stop to set the deceleration point; it is not a lock, so the cylinder will not hold a load without live air pressure. For true load-holding, consider the SAIL or BSAI series.

Theoretical Output Force (Ø125mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 5734 N | 5734 N |
| 0.7 MPa | 8027 N | — |
| Max (@1.0 MPa) | 1169 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 SAIJ125 Adjustable Cylinder SAIJ125X195-10S Is Used
Machine Setup & Changeover
Dial in the exact 185-195 mm retract stop during line changeovers without physically swapping cylinders or repositioning external deadeners.
Variable End-Stop Tuning
Perfect for assemblies requiring precise final positioning, letting operators trim the stroke up to 10 mm to accommodate material thickness variations.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X195-10S the Right Cylinder?
The adjustable-stroke design is selected over a fixed SAI cylinder when a machine requires precise end-stop tuning during commissioning or frequent product-size changeovers. As a dimensionally interchangeable ISO 15552 cylinder, replacement requires matching the 125 mm bore, 195 mm stroke, 10 mm adjustment, PT tapered port threads, and the -S magnet.
Because the 195 mm stroke is relatively short for this bore size, side-load concerns are minimal, though the substantial 32 mm rod and M27x2 thread provide excellent rigidity and side-load resistance. The mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.
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 SAIJ125 Adjustable Cylinder SAIJ125X195-10S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 195 mm nominal stroke by up to 10 mm, creating a 185-195 mm usable travel window. It sets the end-position but does not lock the load without live air pressure.
