About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX75-40S
The AirTAC SAIJ32X75-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 35-75 mm usable travel window. The integrated magnet supports position sensing.
Instead of machining external stops during product changeovers, technicians can dial in the end position directly at the cylinder. The rear adjuster functions purely as a travel stop and relies on live air to maintain the load. For true load-holding without pressure, 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 SAIJ32BX75-40S Is Used
Product Changeovers
Quickly fine-tune the 35-75 mm travel window during line format changes without swapping out the entire actuator.
End-Stop Calibration
Dial in the exact retraction point during machine commissioning to prevent overshoot and ensure precise part placement.
Adjustable Ejection
Vary the ejection distance on the fly for different product sizes using the rear adjustment screw.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX75-40S the Right Cylinder?
Select this 32 mm bore when you need precise end-position tuning within a 35-75 mm window, rather than ordering a fixed-stroke SAI cylinder. To replace an ISO 15552 cylinder, match the 75 mm stroke, 40 mm adjustment, PT port, and -S magnet.
This model operates at speeds of 30-800 mm/s and uses a 12 mm rod with an M10x1.25 thread. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.

- ✓ 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 SAIJ32BX75-40S FAQ
At the maximum operating pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear adjuster allows you to shorten the 75 mm nominal stroke by up to 40 mm, creating a usable travel window of 35-75 mm. The adjuster acts as a mechanical stop and does not lock the load without live air pressure.
