About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-30
The AirTAC SAIJ100X350-30 is a double-acting, adjustable-stroke ISO 15552 profile cylinder featuring a 100mm bore and a 350mm nominal stroke. An integrated rear adjusting screw allows you to dial back the travel by up to 30mm, creating a precise 320-350mm usable end-position window for fine-tuning at commissioning. It delivers robust force, generating 7068N of push thrust at 0.9 MPa and 801 kgf at 1.0 MPa.
Built for demanding environments, this variant features a SUS304 stainless steel rod for superior corrosion resistance and is fitted with PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept CMSE reed or DMSE solid-state switches if position feedback is added later. The variable air cushions at both ends absorb kinetic energy, but note that the rear adjuster acts only as a travel stop, not a load-holding lock.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-30 Is Used
Machine Changeover
Dial in the 30mm stroke adjustment during product size changes to set new end positions without replacing the cylinder or adding external mechanical stops.
Variable End Diverter
Precisely positions a routing flap or diverter arm across a 320-350mm travel window, allowing operators to fine-tune the exact stopping point during commissioning.
Press Fit Tuning
Sets the exact bottoming depth for a 100mm bore press operation, using the rear stopper to compensate for material thickness variations without reprogramming the PLC.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-30 the Right Cylinder?
Choose this 100mm bore when an 80mm cylinder lacks the necessary power, as stepping up from the 80mm bore (which provides 4523N push at 0.9 MPa) to this model yields a substantial 7068N push force at the same pressure. The adjustable stroke is selected over a fixed SAI cylinder when a machine requires variable end-stops or product changeover flexibility without physically swapping the actuator. To match this ISO 15552 footprint, specify a 100mm bore, 350mm stroke, 30mm adjustment, PT port thread, and the SUS304 rod material.
Because the 350mm stroke is substantial, the 25mm rod diameter and M20x1.5 rod thread provide rigidity, but an external guide is still recommended to prevent excessive side-loading on the unsupported piston rod. Remember that the rear adjuster and air cushions only decelerate the load; they do not hold position without live air pressure. For true load-holding, consider an external rod lock, or AirTAC SAIL or BSAI clamp-lock cylinders. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100BX350-30 FAQ
At a 0.9 MPa operating pressure, this 100mm bore cylinder provides 7068N of push force and 5497N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 801 kgf.
The rear adjusting screw acts as a mechanical stop that lets you shorten the 350mm nominal stroke by up to 30mm, yielding a usable travel window of 320-350mm. This allows for fine end-position tuning at commissioning without swapping the cylinder.
