About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX105-50S
The AirTAC SAIJ100X105-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 105 mm travel to a precise usable window of 55-105 mm. It delivers substantial thrust, pushing with 7068 N at 0.9 MPa, making it well-suited for heavy positioning tasks. This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet for position sensing.
Because the adjuster acts purely as a mechanical stop at the retract end, it does not hold the load without live air pressure. For load-holding without continuous air, an external rod lock or related types like SAIL or BSAI are required. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX105-50S Is Used
Precision End-Stop Tuning
Dial in the exact retract distance from 55 to 105 mm during machine commissioning to perfect pressing or clamping depth without swapping hardware.
Product Line Changeover
Quickly adjust the travel window when handling different product sizes on the same conveyor line, saving setup time between production runs.
Heavy Assembly Positioning
Leverage the 7068 N push force at 0.9 MPa to move heavy pallets or fixtures into place, using the rear screw to set the final resting position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX105-50S the Right Cylinder?
Choose this 100 mm bore when 7068 N of push force at 0.9 MPa is required; if your application needs less force, stepping down to an 80 mm bore provides 4523 N. An adjustable stroke is selected over a fixed SAI cylinder when you need fine end-position tuning at commissioning or during product changeover without adding external stops. To replace an ISO 15552 cylinder, match the 100 mm bore, 105 mm stroke, 50 mm adjustment, PT G1/2 port, and -S magnet.
Since the 105 mm stroke is relatively short, side-load risks are minimal, but the robust 25 mm rod and M20x1.5 thread handle high axial stress well. Remember that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.
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 SAIJ100 Adjustable Cylinder SAIJ100AX105-50S FAQ
At an operating pressure of 0.9 MPa, this 100 mm bore cylinder generates a push force of 7068 N and a pull force of 3681 N.
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective travel from the 105 mm nominal stroke down to as little as 55 mm, providing a 55-105 mm usable window.
