About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX105-20S
The AirTAC SAIJ32X105-20-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear mechanical adjuster that allows you to fine-tune the effective stroke within an 85 to 105 mm window. The extruded aluminum barrel includes sensor grooves on both sides, and because this unit includes a magnet (-S), it supports AirTAC CMSE reed and DMSE solid-state switches for precise end-of-travel detection.
The integrated rear stopper screw lets you dial in the exact retract position during commissioning or product changeover without swapping out the cylinder or fabricating external stops. It is important to note that this adjuster acts purely as a travel stop and does not hold the load without live air pressure; for true fail-safe load holding, consider the SAIL or BSAI series instead.

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 SAIJ32AX105-20S Is Used
Machine Changeover
Quickly adjust the retract distance from 85 to 105 mm to accommodate different product lengths on the same production line without changing hardware.
Variable Positioning
Set custom travel limits on packaging or sorting equipment where the rear stopper acts as a precise mechanical end-position boundary.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX105-20S the Right Cylinder?
The adjustable stroke is ideal for machines that require variable end-stops, whereas a fixed-stroke SAI cylinder is sufficient for dedicated single-product lines. This SAIJ32X105-20-S model features PT tapered ports and a SUS420J2 stainless steel rod, making it dimensionally interchangeable with ISO 15552 cylinders. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

- ✓ 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 SAIJ32AX105-20S FAQ
It operates at speeds between 30 and 800 mm/s.
The rear adjuster screw lets you shorten the nominal 105 mm stroke by up to 20 mm, providing a usable travel window of 85 to 105 mm. It functions as a mechanical stop, not a lock, so it cannot hold the load without continuous air pressure.
