About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-10
The AirTAC SAIJ32X240-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window down to 230-240 mm without adding external stops. Equipped with a SUS304 stainless steel rod and PT tapered port threads, it delivers 402 N of push force at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
Because the rear adjuster acts purely as a mechanical stop, it cannot hold a load without live air pressure; for positive load-holding, consider the SAIL or BSAI series. This model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. The 12 mm carbon steel-based rod and M10x1.25 thread handle moderate side loads, though long 240 mm strokes still require an external guide.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-10 Is Used
End-Position Tuning
Dial in the exact 230-240 mm travel during machine commissioning to compensate for mechanical tolerances without swapping cylinders.
Product Changeover
Quickly adjust the retract stop by up to 10 mm to accommodate slight variations in product sizes on a packaging line.
Light Assembly Pushing
Utilize the 402 N push force for precise light-duty assembly tasks where the end-stop must be perfectly dialed in.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX240-10 the Right Cylinder?
Choose this 32 mm bore if your application requires up to 402 N of push force at 0.5 MPa and you need the flexibility to dial in the exact end-of-stroke position during commissioning. If your setup demands higher thrust, stepping up to the 40 mm bore yields 628 N of push force. The 10 mm adjustment range is ideal for compensating for mechanical tolerances or slight product size variations on a line.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 240 mm stroke, PT port threads, and the chosen mounting bracket. Remember that the rear adjuster only sets the retract end position and does not function as a lock; for safety holding without air, explore SAIL or BSAI alternatives. For any stroke of 300 mm or more, ensure you use an external guide to prevent rod binding.

- ✓ 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 SAIJ32BX240-10 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 can deliver up to 82 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 240 mm stroke by up to 10 mm, creating a 230-240 mm usable travel window. It only sets the end position and does not lock the load without live air pressure.
