About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX950-50S
The AirTAC SAIJ32X950-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 900 to 950 mm without swapping components. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet supports CMSE reed and DMSE electronic solid-state switches for precise position feedback.
Because the nominal 950 mm stroke approaches the 1000 mm maximum standard limit for this bore, the 50 mm adjustment range is invaluable for dialing in exact end positions during machine commissioning. The rear adjuster acts purely as a mechanical stop to set the retract end-point, meaning it does not hold the load without live air pressure. For applications requiring true load-holding without continuous pneumatic pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants.

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 SAIJ32AX950-50S Is Used
Machine Setup & Changeover
Dial in the 900-950 mm retract end-position during commissioning or product size changes without machining new external stops.
Variable End-Stop Positioning
Adjust the stroke on the fly to accommodate varying package lengths on a long-transfer conveyor line.
Long-Stroke End Tuning
Fine-tune the final retract position on a 950 mm stroke mechanism to absorb mechanical tolerance stack-ups.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX950-50S the Right Cylinder?
The adjustable-stroke design is selected over a fixed SAI cylinder when setup requires variable end-stops or product changeovers. When ordering a replacement, verify the 950 mm stroke, 50 mm adjustment, PT port thread, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
With a 950 mm stroke, the 12 mm rod and M10x1.25 thread face increased side-load risks. An external guide is strongly recommended to prevent rod binding and premature seal wear. Operating speed ranges from 30 to 800 mm/s.

- ✓ 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 SAIJ32AX950-50S FAQ
The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 50 mm. This creates a 900 to 950 mm usable travel window, but it does not lock or hold the load without live air pressure.
