About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX250-75S
The AirTAC SAIJ32X250-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 175 to 250 mm, letting you dial back the 250 mm nominal stroke by up to 75 mm during commissioning.
This variant features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. It uses a G1/8 port and omits heavy FB or CA mounts, supporting Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces.

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 SAIJ32BX250-75S Is Used
Machine Setup Tuning
Fine-tune the 175-250 mm travel window during initial commissioning to hit exact end positions without adding external stops.
Product Changeover
Quickly adapt the cylinder stroke for different product sizes on a packaging line by rotating the rear adjustment screw.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX250-75S the Right Cylinder?
The 75 mm adjustment range is ideal for product changeovers, allowing variable end-stops without swapping cylinders. Remember, the rear adjuster acts as a travel stop, not a lock; for load-holding without live air, select an SAIL or BSAI cylinder.
As a direct ISO 15552 interchangeable replacement, match your bore, 250 mm stroke, 75 mm adjust, PT G1/8 port, and -S magnet. Because the stroke is 250 mm, ensure external guidance to prevent side-loading on the 12 mm rod.
Quick checklist
- ✓ 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 SAIJ32BX250-75S FAQ
At 0.7 MPa, the push force increases to 563 N.
The rear adjuster allows you to shorten the 250 mm nominal stroke by up to 75 mm, creating a usable travel window of 175 to 250 mm. It acts as a physical stop and does not lock the load without live air.
