About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX50-40S
The AirTAC SAIJ32X50-40-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 10-50 mm usable travel window by allowing you to dial back the 50 mm nominal stroke by up to 40 mm.
This variant includes a -S magnet for position sensing with CMSE reed or DMSE electronic switches. It uses a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and features PT tapered port threads (G1/8). The extruded aluminum barrel integrates sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ32AX50-40S Is Used
Machine Changeover
Dial in the 10-50 mm travel window on the fly to accommodate different product sizes on the same line.
End-Stop Tuning
Hit exact retract positions during commissioning without machining external stopper blocks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX50-40S the Right Cylinder?
Choose this 32 mm bore adjustable-stroke model when you need to fine-tune the end-of-travel position during machine commissioning or product changeovers without swapping out the physical cylinder or adding external stops. The rear adjuster acts strictly as a travel stop and relies on the variable air cushions for end-of-stroke deceleration; it does not hold the load dynamically. For load-holding without live air pressure, consider the SAIL or BSAI series. To match this exact configuration, specify the 32 mm bore, 50 mm stroke, 40 mm adjustment, PT G1/8 port, SUS420J2 rod, and -S magnet.

- ✓ 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 SAIJ32AX50-40S FAQ
The rear adjuster screw lets you shorten the 50 mm nominal stroke by up to 40 mm, creating a 10-50 mm usable travel window. The adjuster acts as a mechanical stop for end-position tuning and does not lock the load without air pressure.
