Airtac SAIJ100 Adjustable Cylinder SAIJ100BX180-30S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100BX180-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 180mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX180-30S
The AirTAC SAIJ100X180-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 7068N push force at 0.9 MPa. By turning the rear stopper screw, you can trim the nominal 180 mm travel back by up to 30 mm, creating a precise 150-180 mm usable end-position window without swapping hardware. This on-machine fine-tuning is ideal for dialing in exact stopping points during commissioning or product changeovers.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and pairs with a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, and because this model carries the -S magnet, it is fully ready for electronic DMSE or reed CMSE position sensing. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 attachments, deliberately omitting FB, CA, CB, and CR brackets to streamline the adjustable setup.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX180-30S Is Used
Machine Changeover
Rapidly modify the 150-180 mm travel window during product size transitions without disassembling the line or adding external stopper blocks.
End-Position Tuning
Dial in the exact retract stop during commissioning to perfect machine timing and crush tolerances on the factory floor.
Heavy Forming Setup
Leverage the 7068N push force at 0.9 MPa for high-load press or forming tasks, adjusting the stroke to accommodate varying material thicknesses.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX180-30S the Right Cylinder?
Choose this 100 mm bore when your application requires heavy thrust that exceeds the 513 kgf limit of an 80 mm bore, but you want to avoid the bulk of a 125 mm unit. The adjustable 150-180 mm travel window is perfect for variable end-stops, whereas a fixed-stroke SAI would lock you into a single 180 mm dimension. The 25 mm rod and M20x1.5 thread handle substantial side loads, but because the 180 mm stroke is substantial, an external guide is still recommended to prevent premature seal wear.
Remember that the rear adjuster acts purely as a travel stop and cannot hold a load without live air pressure. For true load-holding without continuous air, consider the SAIL pneumatic lock, the BSAI clamp-lock, or an external rod lock. To replace an ISO 15552 cylinder, match the 100 mm bore, 180 mm stroke, 30 mm adjustment, PT ports, and the -S magnet.
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 SAIJ100BX180-30S FAQ
At 0.9 MPa, this 100 mm bore cylinder provides 7068N of push force and 6634N of pull force. It can deliver a maximum of 801 kgf at 1.0 MPa.
The rear stopper screw allows you to shorten the 180 mm nominal stroke by up to 30 mm, creating a usable travel window of 150-180 mm. This adjuster is a mechanical stop for end-position tuning, not a lock, and the cylinder will not hold a load without live air.
