Airtac SAIJ100 Adjustable Cylinder SAIJ100BX30-30
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100BX30-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 30mm 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 SAIJ100BX30-30
The AirTAC SAIJ100X30-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 0 to 30 mm usable travel window. Operating at 0.5 MPa, it delivers 3927 N of push force and 3681 N of pull force, making it suited for heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides, though this specific configuration omits the internal magnet.
This model is equipped with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The rear adjuster acts strictly as a travel stop to fine-tune end positions during commissioning; it does not lock or hold the load without live air pressure. For secure load-holding without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX30-30 Is Used
Short-Stroke Clamping
Provides 3927 N of clamping force at 0.5 MPa with a 0-30 mm adjustable window, allowing operators to dial in the exact crush depth on delicate workpieces.
Product Changeover
Quickly fine-tune the end-of-stroke position during format changes on packaging lines without swapping out the physical cylinder or adding external mechanical stops.
Heavy-Duty Ejection
Handles robust ejection tasks using its 3681 N pull force, while the rear stopper ensures the ejection travel is precisely limited to prevent over-travel.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX30-30 the Right Cylinder?
Choose this 100 mm bore when your application requires substantial thrust within a very short, finely-tuned travel range. If you need less force, stepping down to an 80 mm bore yields 2513 N of push force at 0.5 MPa, whereas moving up to a 125 mm bore provides 6136 N. The adjustable rear stopper is ideal for machine setups requiring variable end-stops or product changeovers, eliminating the need to physically swap out a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 30 mm nominal stroke, 0-30 mm adjustment range, PT G1/2 port, and SUS304 rod material. Because this is a non-magnet configuration, position sensing via CMSE reed or DMSE electronic switches is not supported without adding an -S magnet. For any stroke length of 300 mm or more, an external guide is recommended to manage side loads.
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 SAIJ100BX30-30 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 801 kgf.
The rear adjusting screw acts as a mechanical stopper, allowing you to trim the effective stroke down from 30 mm to 0 mm. This creates a 0-30 mm usable travel window for fine-tuning end positions at commissioning, but it does not lock the load without live air pressure.
