About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X155-50
The AirTAC SAIJ32X155-50 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 155 mm stroke that can be dialed back by up to 50 mm, yielding a usable travel window of 105 to 155 mm. In the compact 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This adjustable design eliminates the need to swap cylinders or add external stops during product changeovers. It features a standard carbon steel piston rod and PT tapered port threads (G1/8). The rear adjuster acts strictly as a travel stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X155-50 Is Used
Machine Changeovers
Dial in the 105-155 mm travel window during product size changes without physically swapping the actuator or adding external mechanical stops.
End-Stop Calibration
Fine-tune the retract position at commissioning to achieve exact positioning, using the rear screw to absorb minor mechanical tolerances.
Light Assembly Automation
Utilize the 402 N push force for compact positioning tasks where the final end-of-stroke destination must be tweaked on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X155-50 the Right Cylinder?
Choose this 32 mm bore when you need precise retract-end positioning within a 105-155 mm travel window. If your application requires greater thrust, stepping up to the 40 mm bore provides 628 N of push force at 0.5 MPa. Conversely, if you need a fixed end position without commissioning adjustments, the standard SAI cylinder is a simpler alternative.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 155 mm stroke, 50 mm adjustment range, PT port threads, and your required mounting accessories. The SAIJ series supports a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead of relying on this adjuster.
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 SAIJ32X155-50 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjuster allows you to shorten the 155 mm nominal stroke by up to 50 mm, creating a usable travel window of 105 to 155 mm. The adjuster acts as a mechanical stop and does not function as a lock to hold the load without air pressure.
