About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX120-10
The AirTAC SAIJ32X120-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 110-120 mm usable travel window, allowing you to dial back the 120 mm nominal stroke by up to 10 mm during machine commissioning. In the 32 mm bore class, it delivers a 402 N push force at 0.5 MPa and features a 12 mm stainless steel (SUS304) piston rod.
This adjustable-stroke design eliminates the need to swap cylinders or add external stops when fine-tuning end positions. The extruded aluminum barrel includes sensor grooves on both sides, and the rear adjuster acts purely as a travel stop, not a load-holding lock. It uses a PT G1/8 port and operates at speeds of 30-800 mm/s.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX120-10 Is Used
Machine Commissioning
Dial in the exact 110-120 mm end-position during setup without physically swapping cylinders or adding external stopper blocks.
Product Changeover
Quickly adjust the retract stop by up to 10 mm to accommodate minor product size variations on the production line.
Precision Positioning
Fine-tune the end-of-stroke location for light-duty assembly tasks requiring repeatable 402 N force at 0.5 MPa.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX120-10 the Right Cylinder?
Choose this 32 mm bore when your application requires up to 402 N of push force at 0.5 MPa; step up to the 40 mm bore if you need 628 N. An adjustable stroke is ideal for setups requiring variable end-stops or product changeover, whereas a fixed SAI cylinder suits static stops. For load-holding without live air pressure, consider the SAIL or BSAI series, as this adjuster only sets the travel end. This model features a PT G1/8 port, SUS304 rod, no magnet, and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

- ✓ 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 SAIJ32BX120-10 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides a 402 N push force and a 345 N pull force. At the maximum 1.0 MPa operating pressure, it delivers up to 80 kgf.
The rear adjuster screw lets you shorten the effective travel from the 120 mm nominal stroke down to 110 mm. It acts as a mechanical stop to fine-tune the retract position without needing a different cylinder.
