Airtac SAIJ100 Adjustable Cylinder SAIJ100BX900-30S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100BX900-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 900mm 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 SAIJ100BX900-30S
The AirTAC SAIJ100X900-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the nominal 900 mm travel by up to 30 mm for a precise 870-900 mm setup window. It delivers robust performance with 3927 N of push force at 0.5 MPa and reaches a maximum of 801 kgf at 1.0 MPa. The extruded aluminum barrel integrates dual sensor grooves, and because this unit includes a magnet (-S), it supports AirTAC CMSE reed and DMSE solid-state switches for exact end-of-stroke detection.
Built for demanding environments, this variant features a SUS304 stainless steel rod (option B) for superior corrosion resistance and carries PT tapered port threads (G1/2). The 25 mm rod diameter and M20x1.5 rod thread provide a robust interface that handles high side loads well, though any 900 mm stroke still requires an external guide to prevent rod bending. The adjustable rear stopper acts purely as a travel end-limit and deceleration point, meaning it will not hold the load if air pressure drops.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX900-30S Is Used
Machine Changeover
Fine-tune the 870-900 mm retract distance during product size changes without physically remounting the cylinder or adding external shims.
Long-Stroke Pressing
Applies up to 801 kgf of pressing force at 1.0 MPa while using the rear screw to set the exact bottoming-out position for assembly operations.
Variable End-Stop Diverter
Adjusts the stroke end-point on the fly to accommodate different package sizes on a sorting conveyor without changing the pneumatic footprint.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX900-30S the Right Cylinder?
Select this 100 mm bore model when an application requires substantial thrust—such as 3927 N push at 0.5 MPa—combined with the ability to fine-tune the retract position during commissioning without swapping cylinders or adding external stops. If your process requires less force, stepping down to an 80 mm bore yields 2513 N push at 0.5 MPa, whereas moving up to a 125 mm bore provides 6136 N. The rear adjuster on this SAIJ allows up to 30 mm of trimming, making it ideal for product changeovers on automated lines.
Because the 900 mm stroke is substantial, always pair this cylinder with an external linear guide to manage side loads and prevent rod damage. This unit is dimensionally interchangeable per ISO 15552, uses PT G1/2 ports, and offers a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the rear adjuster is a stop, not a lock; for true load-holding without live air, specify a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead.
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 SAIJ100BX900-30S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. If operated at the maximum 1.0 MPa pressure, it delivers up to 801 kgf of push force.
The rear adjuster screw allows you to shorten the 900 mm nominal stroke by up to 30 mm, creating a usable travel window of 870-900 mm. This stopper sets the end position and deceleration but does not lock the load without continuous air pressure.
