About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-100
The AirTAC SAIJ32X145-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 145 mm stroke that can be dialed back by up to 100 mm, yielding a highly flexible 45-145 mm usable travel window for precise end-position tuning during commissioning. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty positioning tasks.
This variant incorporates a SUS304 stainless steel rod for superior corrosion resistance and ships with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE or DMSE switches later if position feedback becomes necessary.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-100 Is Used
Machine Changeover
Dial in the 45-145 mm travel window during product size changes without physically swapping cylinders on the line.
End-Position Tuning
Fine-tune the retract stop at commissioning to perfect seating or clamping depth without adding external mechanical stops.
Adjustable Ejector
Vary the ejection distance on the fly to safely push different sized parts out of a testing fixture.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-100 the Right Cylinder?
Select this 32 mm bore when an application requires variable end-stops within a 45-145 mm range, avoiding the need to stock multiple fixed-stroke SAI cylinders or bolt on external stops. If your setup needs greater thrust, stepping up to the 40 mm bore increases push force to 628 N at 0.5 MPa. Because the 145 mm stroke is under 300 mm, side-load stress on the 12 mm rod is manageable, though external guides remain recommended for heavy off-center loads.
To match this exact configuration for an ISO 15552 replacement, specify the 32 mm bore, 145 mm stroke, 100 mm adjustment range, PT ports, SUS304 (B) rod material, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Remember that the rear adjuster acts only as a travel stop; it cannot hold a load without live air, so consider an external rod lock or SAIL cylinder for fail-safe load holding.
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 SAIJ32BX145-100 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If operated at 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw lets you shorten the 145 mm nominal stroke by up to 100 mm, creating a usable travel window of 45 to 145 mm. This stopper only sets the travel end point and does not lock the load without continuous air pressure.
