About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-40S
The AirTAC SAIJ100X80-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 40 to 80 mm, letting you dial back the nominal 80 mm stroke by up to 40 mm during commissioning. Delivering 3927 N of push force at 0.5 MPa, it handles substantial workloads while maintaining standard ISO 15552 mounting dimensions.
This specific SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting options cover Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-40S Is Used
Precision End-Stop Tuning
Dial in the exact retract position within a 40 to 80 mm window during machine commissioning without swapping out the entire cylinder.
Product Changeover
Quickly adapt the cylinder stroke on packaging lines handling varying product sizes by adjusting the rear stopper screw.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod for reliable actuation in washdown or mildly corrosive manufacturing environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-40S the Right Cylinder?
Select this 100 mm bore cylinder when an application requires 3927 N of push force at 0.5 MPa and on-the-fly end-position tuning. If your process needs less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa. The rear adjuster screw acts purely as a travel stop to fine-tune the retract position without adding external stops, but it does not hold the load without live air; for fail-safe load holding, consider an SAIL or BSAI cylinder.
To match this exact configuration for an ISO 15552 replacement, verify the 100 mm bore, 80 mm nominal stroke, 40 mm adjustment range, PT tapered port threads, and the -S magnet option. Operating speed spans 30 to 800 mm/s, making it highly responsive for dynamic cycles.
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 SAIJ100BX80-40S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. It can deliver up to 7068 N of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 80 mm down to 40 mm. This creates a 40 to 80 mm usable travel window for fine-tuning end positions without replacing the cylinder.
