About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-75
The AirTAC SAIJ32X210-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 402N of push force at 0.5 MPa. Its integrated 75mm adjustment screw creates a usable travel window of 135-210mm, allowing precise end-position tuning without swapping hardware. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G1/8 connection. The rear stopper sets the retract limit but does not lock the load, meaning live air is required to maintain position. For load-holding without pressure, consider an external rod lock or the SAIL series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-75 Is Used
Stroke Calibration
Dial in the exact 135-210mm retract position during machine setup to accommodate varying product sizes without adding external stopper blocks.
Assembly Positioning
Fine-tune the end-of-stroke point on an assembly line, leveraging the 12mm rod and adjustable stop to safely trigger the next mechanical operation.
Machine Changeover
Rapidly adjust the travel window by up to 75mm when switching production runs, avoiding the downtime of physically replacing the entire cylinder.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-75 the Right Cylinder?
Choose this 32mm bore when an application requires fine-tuning the retract distance during commissioning or product changeover, stepping up from a smaller unit if 402N at 0.5 MPa is insufficient. Unlike a fixed-stroke SAI cylinder, the 75mm adjustment window accommodates variable end-stops on the fly. Because the nominal stroke is 210mm, ensure adequate side-load support using external guides to protect the 12mm rod. When specifying a replacement, match the 32mm bore, 210mm stroke, PT port, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting interface.
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 SAIJ32BX210-75 FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. The 210mm nominal stroke combined with the 75mm adjuster yields a usable travel window of 135-210mm.
No, the rear adjuster acts only as a travel stop to set the end position and does not function as a lock or brake. The cylinder requires live air to hold a load; for dead-air holding, use a SAIL or BSAI series cylinder.
