About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX155-10
The AirTAC SAIJ32X155-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 155 mm travel by up to 10 mm for a precise 145-155 mm usable window. Featuring a 32 mm bore, it delivers 402 N of push force at 0.5 MPa and utilizes a PT tapered port with an M10x1.25 rod thread. The SUS304 stainless steel rod provides excellent corrosion resistance for harsher environments.
Unlike a fixed-stroke SAI, this rear screw stopper lets you fine-tune the retract end position during commissioning without adding external stops. The adjuster acts purely as a travel stop and does not hold the load without live air. It retains standard variable air cushions at both ends and features an extruded aluminum barrel with sensor grooves on both sides.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX155-10 Is Used
End-Position Tuning
Dial in the exact retract distance within a 145-155 mm window during commissioning without swapping cylinders or adding external mechanical stops.
Product Changeover
Quickly adjust the stroke by up to 10 mm to accommodate slight variations in product sizes on a packaging or handling line.
Corrosive Setup
Leverage the SUS304 stainless steel rod for light-duty positioning tasks in environments where standard carbon steel rods might corrode.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX155-10 the Right Cylinder?
Choose this 32 mm bore when your application requires around 402 N of push force at 0.5 MPa; step up to the 40 mm bore if you need 628 N, or down if your load is lighter. The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers. For holding a load without live air pressure, select a SAIL (air-released lock) or BSAI (clamp-lock) instead of relying on this adjuster. To match this cylinder for an ISO 15552 replacement, specify the 155 mm stroke, 10 mm adjustment, PT port, and no magnet. Since the stroke is under 300 mm, side-load stress is minimal, but always guide the load for optimal rod life.
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 SAIJ32BX155-10 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 0.7 MPa, the push force increases to 563 N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 155 mm down to as little as 145 mm. It only sets the travel end and does not lock or hold the load without continuous air pressure.
