About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX155-75S
The AirTAC SAIJ32X155-75-S 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 fine-tuned backward by up to 75 mm, yielding a highly flexible 80-155 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod and includes a magnet for position sensing.
This adjustable-stroke design allows you to dial in the exact retract end-position during commissioning without swapping hardware. The extruded aluminum barrel features sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. The rear screw acts purely as a travel stop for deceleration alongside the standard air cushions, meaning it will not hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX155-75S Is Used
Product Changeover
Quickly adjust the 80-155 mm travel window to accommodate different package sizes on a packaging line without changing the cylinder.
End-Stop Calibration
Fine-tune the retract position during machine commissioning to achieve precise mechanical alignment without adding external stopper blocks.
Sensor Mapping
Utilize the integrated magnet with DMSE electronic sensors to accurately track the piston across the adjusted travel range.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX155-75S the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning within an 80-155 mm travel window. If your setup needs greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The SAIJ32X155-75-S is specified with a PT tapered port, a SUS304 stainless steel rod, and a magnet (-S) for CMSE / DMSE sensors. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because the 155 mm stroke is relatively short for this bore size, side-load risks are minimal, though external guides remain good practice for rigid lateral stability. Remember that the rear adjuster is a stop, not a locking mechanism; if you need true load-holding without continuous air pressure, consider an AirTAC SAIL or BSAI cylinder instead. The operating speed range for this model is 30-800 mm/s.
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 SAIJ32BX155-75S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If operated at 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the effective stroke from its 155 mm nominal length by up to 75 mm. This creates an adjustable 80-155 mm travel window, acting as a mechanical stop rather than a load lock.
