About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX155-75
The AirTAC SAIJ100X155-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 155 mm stroke by up to 75 mm. This yields a highly flexible usable travel window of 80 to 155 mm, enabling precise end-position tuning at commissioning without swapping out the cylinder or adding external stops. The 100 mm bore generates 3927 N of push force and 3681 N of pull force at 0.5 MPa, making it well-suited for heavy payload manipulation.
This specific configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsh environments. Fluid supply is routed through PT tapered G1/2 ports, while the extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. The adjustable rear stopper acts purely as a travel end-deceleration device and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX155-75 Is Used
Product Changeover
Dial in the exact retract distance from 80 to 155 mm during machine format changes without disassembling the line or installing shims.
End-Position Tuning
Fine-tune the final deceleration point at commissioning using the rear adjuster to accommodate sensor placement and mechanical stops.
Harsh Environment Actuation
Leverage the SUS304 stainless steel rod to push 3927 N loads in washdown or corrosive manufacturing settings safely.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX155-75 the Right Cylinder?
Select this 100 mm bore cylinder when your application requires substantial thrust—up to 3927 N at 0.5 MPa—but demands an adaptable end-stop. If you need less force, stepping down to an 80 mm bore yields 2513 N of push force; if you need more, a 125 mm bore provides 6136 N. Choose the SAIJ adjustable-stroke variant over a fixed SAI model when you anticipate product changeovers or need to fine-tune the retract position on the fly.
Because the 155 mm stroke is relatively short, side-load stress on the 25 mm rod is manageable, but always ensure adequate guiding for heavy loads. This model uses PT G1/2 ports and omits the FB, CA, CB, and CR mounting styles, offering instead Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces. For load-holding without continuous air pressure, consider the SAIL or BSAI series, as the SAIJ rear adjuster is a stop, not a lock.
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 SAIJ100BX155-75 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. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster allows you to shorten the effective stroke from the nominal 155 mm by up to 75 mm. This creates a usable travel window of 80 to 155 mm, letting you set the exact end position without replacing the cylinder.
