About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-100S
The AirTAC SAIJ32X650-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 650 mm nominal stroke that can be dialed back by up to 100 mm, creating a 550-650 mm usable travel window for exact end-position tuning during commissioning. Operating at 30-800 mm/s, it delivers a 402 N push force at 0.5 MPa. The barrel is extruded aluminum, distinct from tie-rod designs, and this -S configuration includes a magnet for CMSE and DMSE sensors.
This specific SKU features a SUS304 stainless steel rod (code B) and PT tapered port threads, making it highly suitable for environments where corrosion resistance is necessary. The 12 mm rod and M10x1.25 thread handle moderate side loads, though long unsupported strokes require external guidance. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-100S Is Used
Variable End Stops
Dial in the exact 550-650 mm retraction point during machine setup without adding external mechanical stops.
Product Changeover
Quickly adjust the cylinder's effective stroke on the line to accommodate different package lengths.
Commissioning Tuning
Fine-tune the end-of-stroke position during initial machine commissioning to perfect timing sequences.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-100S the Right Cylinder?
Choose this 32 mm bore when you need the precise 550-650 mm travel window for product changeovers or variable end stops without swapping cylinders. It provides 402 N of push force at 0.5 MPa; if your application requires less force, a smaller bore is needed, but stepping up to a 40 mm bore yields 628 N. Because the stroke is 650 mm, an external guide is recommended to manage side loads on the 12 mm rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For load-holding without live pressure, select a SAIL or BSAI cylinder instead, as this adjuster is not a lock.
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 SAIJ32BX650-100S FAQ
At 0.5 MPa it provides 402 N of push force and 345 N of pull force. At 0.7 MPa the push force increases to 563 N.
A rear screw stopper lets you trim the 650 mm nominal stroke back by up to 100 mm, creating a 550-650 mm adjustable travel window. It sets the end position but does not lock the load.
