About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-30
The AirTAC SAIJ100X800-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 3927N of push force at 0.5 MPa. It features a SUS304 stainless steel rod and PT tapered ports. By turning the rear screw, you achieve a 770-800mm usable travel window, perfect for dialing in exact end positions without swapping hardware.
This 100mm bore actuator omits the FB, CA, CB, and CR mounting styles, utilizing a focused set of ISO 15552 interfaces including Basic, FA, LB, TC, FTC, TCM1, and TCM2. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU lacks a magnet for CMSE or DMSE switches.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-30 Is Used
Machine Setup Changeover
Fine-tune the 770-800mm retract position during product family changeovers without disassembling tooling or adding external shims.
Variable End-Stop Positioning
Dial in the exact end-of-stroke location for automated assembly presses requiring precise 3927N clamping at 0.5 MPa.
Long-Stroke Material Handling
Actuate large diverter gates over an 800mm span, using the rear adjuster to synchronize stopping points across multiple lanes.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX800-30 the Right Cylinder?
Choose this 100mm bore when an 80mm cylinder (providing 2513N push at 0.5 MPa) lacks the thrust for your 800mm stroke application. The 30mm adjustment window is ideal for product changeovers, allowing you to fine-tune the retract end-stop during commissioning rather than machining external stops. If your process requires holding a load without live air pressure, note that this rear adjuster acts only as a travel stop, not a lock; you should select an SAIL or BSAI cylinder instead.
Because the 800mm stroke is lengthy, the 25mm rod should be guided externally to prevent excessive side-loading and premature seal wear. To match this ISO 15552 cylinder exactly, specify the 100mm bore, 800mm stroke, 30mm adjustment, PT port thread, SUS304 rod material, and no 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 SAIJ100BX800-30 FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjuster screw allows you to shorten the effective stroke by up to 30mm, creating a 770-800mm usable travel window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without air pressure.
