About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX240-10S
The AirTAC SAIJ100X240-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 7068N of push force at 0.9 MPa and incorporates a SUS304 stainless steel rod for superior corrosion resistance. By turning the rear screw, you can fine-tune the effective travel window down from the 240mm nominal stroke to a 230mm minimum, achieving precise end-position calibration without external stops.
This adjustable-stroke design is ideal for product changeovers on a packaging line, letting you dial in the exact 10mm variance at commissioning. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed and DMSE electronic switches. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX240-10S Is Used
Machine Changeover
Dial in the 10mm stroke variance during product size transitions on a packaging line without swapping out the entire cylinder assembly.
End-Position Tuning
Achieve precise mechanical calibration at commissioning by trimming the 240mm nominal travel back to 230mm to meet exact process tolerances.
Variable End Stops
Replace fixed external stopper blocks with the integrated rear adjuster to streamline the assembly footprint on heavy machinery.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX240-10S the Right Cylinder?
Choose this SAIJ100X240-10-S model when your application requires the high thrust of a 100mm bore but demands on-the-fly end-position tuning. If you need less force, stepping down to an 80mm bore yields 4523N of push force at 0.9 MPa. Select this adjustable variant over a fixed SAI cylinder when machine setups involve frequent product size changes that require a variable end-stop rather than machining new hard stops.
Because the 240mm stroke exceeds 300mm? No, but even at 240mm, long unsupported strokes should use an external guide to prevent side-loading damage to the M20x1.5 rod thread. Remember that the rear adjuster acts only as a travel stop and the air cushions handle deceleration; neither holds the load without live air. For true load-holding without pressure, consider the SAIL lock or BSAI clamp-lock cylinders. Replacement requires matching the 100mm bore, 240mm stroke, 10mm adjust, PT tapered port, and -S magnet.

- ✓ 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 SAIJ100 Adjustable Cylinder SAIJ100BX240-10S FAQ
The rear adjusting screw acts as a mechanical stopper that allows you to trim the effective stroke by up to 10mm. This creates a usable travel window of 230 to 240mm, enabling fine-tuning of the end position at commissioning without changing the cylinder.
At an operating pressure of 0.9 MPa, the SAIJ100X240-10-S generates a push force of 7068N and a pull force of 3681N. The maximum push force at 1.0 MPa is 801 kgf.
