About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-100S
The AirTAC SAIJ32X800-100-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, equipped with a SUS304 stainless steel rod and a magnet for CMSE or DMSE sensors. It delivers 402N of push force at 0.5 MPa and features a 12mm rod with an M10x1.25 thread. The integrated rear stopper provides a usable travel window of 700-800mm, letting you dial back the 800mm nominal stroke by up to 100mm.
This adjustable design eliminates the need to swap cylinders or bolt on external stops during commissioning. The PT tapered port ensures a tight seal, while the extruded aluminum barrel includes sensor grooves on both sides. Remember the rear adjuster acts only as a travel stop and relies on live air; it does not hold the load mechanically without pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-100S Is Used
Machine Setup Tuning
Dial in the exact end-of-stroke position during commissioning without swapping out the physical cylinder or adding external stopper blocks.
Product Size Changeover
Quickly adjust the 700-800mm travel window to accommodate varying package lengths on a packaging line during product transitions.
Long-Travel Positioning
Fine-tune the retract end-position on a long-stroke assembly station to ensure precise alignment before the final clamping operation.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX800-100S the Right Cylinder?
Choose this 32mm bore when you need precise end-position tuning over a long 800mm travel, stepping up from a smaller unit or down from a 40mm bore (which yields 628N push at 0.5 MPa) if your force requirements are lower. The 100mm adjustment window is perfect for product changeovers on a line, giving you a variable end-stop without replacing the actuator. Because the stroke is 800mm, an external guide is recommended to manage side-load on the 12mm rod.
For ISO 15552 replacement matching, specify a 32mm bore, 800mm stroke, 100mm adjustment, PT port thread, and the -S magnet. This cylinder uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. If your application requires true load-holding without live air, this cylinder is not a lock; consider an external rod lock or the AirTAC SAIL series instead.

- ✓ 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 SAIJ32BX800-100S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can reach up to 724N of push force at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 800mm nominal stroke by up to 100mm, creating a usable travel window of 700-800mm. It requires live air to function and does not mechanically lock or hold the load.
