Airtac Adjustable Cylinder SAIJ32 SAIJ32AX950-40
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX950-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 950mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX950-40
The AirTAC SAIJ32X950-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 950 mm travel by up to 40 mm for a precise 910 to 950 mm usable window.
Because the 950 mm stroke approaches the 1000 mm maximum limit for this 32 mm bore, the 12 mm rod diameter and M10x1.25 thread require careful alignment to prevent excessive side-loading. The rear stopper acts purely as a travel end-position setter for commissioning; it is not a locking device and cannot hold a load without continuous live air pressure.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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 Adjustable Cylinder SAIJ32 SAIJ32AX950-40 Is Used
Machine Changeover
Fine-tune the 910-950 mm travel window during product size changes without adding external stopper blocks to the machine frame.
End-Position Tuning
Dial in the exact retract position at commissioning using the rear adjuster to compensate for mechanical tolerances over a long 950 mm stroke.
Extended Reach Sorting
Push items across a wide conveyor belt, using the 40 mm adjustment to perfectly align the extended pusher face with varying product widths.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX950-40 the Right Cylinder?
If your setup demands less force, stepping down is not an option below 32 mm in this series, but stepping up to a 40 mm bore yields 628 N. The adjustable stroke is selected over a fixed SAI cylinder when you need variable end-stops for product changeovers without physically swapping components.
For an exact ISO 15552 replacement, match the 32 mm bore, 950 mm stroke, 40 mm adjustment range, PT tapered port threads, and your required mounting accessories. Note that SAIJ supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Given the 950 mm stroke, adding an external guide is strongly recommended to support the load and mitigate rod bending.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32AX950-40 FAQ
The maximum push force reaches 724 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 950 mm down to 910 mm. This creates a 910-950 mm usable window for fine-tuning the end position at commissioning without replacing the cylinder.
