About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX180-100S
The AirTAC SAIJ100X180-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to trim the nominal 180 mm travel back by up to 100 mm. This creates a highly flexible 80-180 mm usable stroke window, enabling precise end-position calibration during commissioning or product changeovers without swapping out the entire unit. It delivers robust thrust, generating 3927 N of push force and 3681 N of pull force at a 0.5 MPa operating pressure.
This specific configuration incorporates a SUS304 stainless steel rod for superior corrosion resistance and includes a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the unit is fitted with PT tapered port threads (G1/2). It utilizes the standard SAIJ mounting set—Basic, FA, LB, TC, FTC, TCM1, and TCM2—omitting the FB, CA, CB, and CR options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX180-100S Is Used
Machine Changeover
Quickly dial in the 80-180 mm stroke window during product size transitions on a packaging line without physically replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract end-stop during machine commissioning to perfect a pressing or clamping operation, absorbing mechanical tolerances directly at the rear adjuster.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod and 3927 N of thrust for heavy-duty positioning tasks in washdown or mildly corrosive manufacturing environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX180-100S the Right Cylinder?
Select this 100 mm bore cylinder when your application requires substantial force—up to 7068 N at 0.9 MPa—combined with a wide range of adjustable travel. If your process only needs 2805 N of push force at 0.5 MPa, stepping down to a 63 mm bore saves space and air consumption. Conversely, heavier loads demanding 4523 N at 0.5 MPa would necessitate moving up to an 80 mm bore. The 100 mm bore's 25 mm rod and M20x1.5 thread provide excellent rigidity, but for this 180 mm stroke, you should still ensure external guiding if the load is heavy or subject to offset moments.
The rear adjuster acts purely as a mechanical stop to tune the retract position and must not be relied upon to hold a load without continuous air pressure. If your setup requires true position holding or drop prevention without live air, you should integrate an external pilot-operated check valve or select an AirTAC SAIL (air-released lock) or BSAI (clamp-lock) cylinder. To achieve an exact ISO 15552 replacement match, verify the 100 mm bore, 180 mm stroke, 100 mm adjustment range, PT G1/2 ports, and the -S magnet requirement.
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 SAIJ100BX180-100S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. At its maximum 1.0 MPa operating pressure, it can deliver up to 801 kgf of thrust.
The rear adjuster allows you to mechanically shorten the nominal 180 mm stroke by up to 100 mm, providing an adjustable travel window of 80 to 180 mm. The adjuster functions as a travel stop to set the end position and does not lock or hold the load without live air pressure.
