About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX155-20
The AirTAC SAIJ32X155-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 135-155 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it is equipped with a SUS304 stainless steel rod and PT tapered ports for reliable pneumatic connections.
This adjustable-stroke model utilizes a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR options. The rear stopper screw acts only as a travel end-point deceleration mechanism, not a load hold, requiring live air to maintain position.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX155-20 Is Used
Machine Setup Calibration
Dial in the exact 135-155 mm end position during initial machine commissioning to accommodate mechanical tolerances without swapping cylinders.
Product Size Changeover
Quickly adjust the retract stop to handle varying product lengths on a packaging line, reducing downtime between production runs.
Variable End Stops
Use the rear adjuster to fine-tune the stroke end-point for delicate pressing or positioning tasks that require precise travel limits.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX155-20 the Right Cylinder?
Choose this 32 mm bore when you need 402 N of thrust at 0.5 MPa and the ability to fine-tune the retract end position during commissioning without adding external stops. If your application requires less force, dropping to a 20 mm bore is not an option in this series, but stepping up to a 40 mm bore provides 628 N of push force at 0.5 MPa for heavier loads.
For position holding without continuous air pressure, this cylinder will not suffice; consider the SAIL or BSAI series instead. To replace an ISO 15552 cylinder, match the 32 mm bore, 155 mm stroke, 20 mm adjustment, PT ports, and the SUS304 rod material.
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 SAIJ32BX155-20 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 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm, creating a usable travel window of 135 to 155 mm. This stopper only sets the travel end and does not lock the load without live air pressure.
