About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX250-10
The AirTAC SAIJ32X250-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the retract end position by up to 10 mm. This yields a usable travel window of 240 to 250 mm, perfect for dialing in exact end-of-stroke positions without adding external stops. It delivers 402 N of push force at 0.5 MPa and features a SUS420J2 stainless steel rod for improved corrosion resistance.
This 32 mm bore model uses a PT G1/8 port and includes adjustable air cushions at both ends to manage kinetic energy. The extruded aluminum barrel features sensor grooves on both sides; adding a -S magnet later enables CMSE reed or DMSE electronic solid-state switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX250-10 Is Used
End-Stop Calibration
Dial in the exact 240 to 250 mm retract position during machine commissioning without swapping out the entire actuator.
Product Changeover
Quickly adjust the stroke by a few millimeters on a packaging line when switching to a slightly different product size.
Fixture Positioning
Set precise clamping locations on machining fixtures where a fixed-stroke SAI cylinder would require shimming.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX250-10 the Right Cylinder?
Choose this 32 mm bore cylinder when you need 402 N push force at 0.5 MPa with precise end-position tuning; step up to a 40 mm bore if your application requires 628 N. The 10 mm rear adjuster is a travel stop, not a lock, meaning it cannot hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series. To match this ISO 15552 replacement exactly, verify the 250 mm stroke, 10 mm adjustment range, PT G1/8 port, and your required mounting kit. Since the stroke is 250 mm, ensure external guiding is used to prevent excessive 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 SAIJ32AX250-10 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 250 mm nominal stroke by up to 10 mm, creating a 240 to 250 mm travel window. It only sets the end position and does not lock the load without air pressure.
