About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX20-20S
The AirTAC SAIJ32X20-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 0-20 mm. The integrated -S magnet supports AirTAC CMSE reed and DMSE electronic sensors for precise position detection.
This model features a SUS420J2 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads (G1/8). The rear adjuster acts purely as a mechanical stop for end-position tuning; it does not lock or hold the load without continuous air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ32AX20-20S Is Used
Tooling Setup
Dial in the exact clamping end-stop during machine changeovers without physically swapping the actuator.
Sensor Calibration
Leverage the -S magnet with DMSE solid-state sensors to trigger commands at custom retracted positions.
Lab Automation
Ideal for compact testing rigs where the SUS420J2 rod resists minor splashes and the stroke needs micro-adjustments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX20-20S the Right Cylinder?
Choose this 32 mm bore when you need to trim a 20 mm nominal stroke down to a near-zero position during machine commissioning, avoiding the need to swap cylinders or add external stops. Conversely, if lower force is acceptable, this bore is the optimal minimum.
When matching an ISO 15552 replacement, verify the 20 mm stroke, 20 mm adjustment range, PT port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR variants found in other series.

- ✓ 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 SAIJ32AX20-20S FAQ
The rear adjuster screw lets you mechanically shorten the 20 mm nominal stroke by up to 20 mm, providing a usable travel window of 0-20 mm. It functions as a travel stop for fine-tuning and does not lock the load without live air pressure.
At 0.7 MPa, the push force increases to 563 N.
