About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-100S
The AirTAC SAIJ32X180-100-S is a double-acting ISO 15552 profile cylinder with a rear-mounted stroke adjuster. It features a SUS304 stainless steel rod and a PT tapered port. The built-in magnet supports CMSE reed and DMSE electronic sensors. By turning the rear screw, you can trim the nominal 180 mm stroke back by up to 100 mm, creating a usable travel window of 80-180 mm without adding external stops.
Delivering 402 N push force at 0.5 MPa, this 32 mm bore unit uses a 12 mm rod and M10x1.25 thread. It includes adjustable air cushions at both ends to manage deceleration. The mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB and CA options. This profile cylinder is dimensionally interchangeable with other ISO 15552 cylinders.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-100S Is Used
Machine Changeover
Dial in the 80-180 mm travel window to accommodate different product lengths on the same line without swapping cylinders.
End-Stop Tuning
Use the rear adjuster to set exact retract positions during initial commissioning, eliminating the need for external mechanical stops.
Sensor Integration
The integrated magnet pairs directly with DMSE solid-state and CMSE reed switches mounted in the dual sensor grooves.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-100S the Right Cylinder?
Choose this adjustable model over a fixed SAI when you need to fine-tune the retract end position during commissioning or product changeover. If your application requires less force, stepping down is not an option from this bore, but stepping up to a 40 mm bore yields 628 N push force at 0.5 MPa. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series. Since the 180 mm stroke is under 300 mm, side-load risks are lower, but an external guide is still recommended for heavy lateral loads.
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 SAIJ32BX180-100S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N push force at 0.9 MPa.
The rear adjuster screw lets you shorten the 180 mm nominal stroke by up to 100 mm, providing an adjustable travel window of 80 to 180 mm. The adjuster is a stop, not a lock, so the cylinder still requires live air to hold the load.
