About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-100
The AirTAC SAIJ80X100-100 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N push force at 0.5 MPa, featuring a 25mm piston rod and G3/8 ports. With a nominal 100mm stroke and a 100mm adjustment code, this model provides a highly flexible usable travel window of 0 to 100mm, allowing you to dial in the exact end position without swapping hardware.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches if a magnet is added later. The rear adjuster acts purely as a mechanical stop for position tuning, meaning it does not lock the load without continuous live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-100 Is Used
Variable End-Stop Tuning
Dial in the precise retract distance from 0 to 100mm during machine commissioning to accommodate different material thicknesses without changing cylinders.
Product Size Changeovers
Quickly adjust the stroke window on packaging lines when switching between different product sizes, minimizing downtime and avoiding external stop hardware.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for reliable clamping and positioning tasks in washdown or mildly corrosive manufacturing environments.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-100 the Right Cylinder?
Choose this 80mm bore cylinder when an application requires substantial force—delivering 2513N push at 0.5 MPa—combined with extreme stroke variability. If your setup needs less force, stepping down to a 63mm bore yields 1559N, whereas moving up to a 100mm bore provides 3927N. The 0-100mm adjustable window is ideal for prototyping or product changeovers where the exact end-stop distance changes frequently, eliminating the need to purchase multiple fixed-stroke SAI cylinders.
When integrating this model, ensure the 25mm rod and M20x1.5 rod thread are aligned to handle expected side loads, though long unsupported strokes still require external guiding. For load-holding without live air pressure, the adjuster here is not a brake; you would need to specify a SAIL air-released lock or BSAI clamp-lock cylinder instead. To match this exact configuration for an ISO 15552 replacement, specify: 80mm bore, 100mm nominal stroke, 100mm adjustment, PT ports, SUS304 rod, no magnet, and mounting from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ80 Adjustable Cylinder SAIJ80BX100-100 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjusting screw lets you mechanically shorten the effective travel anywhere within a 0 to 100mm window from the nominal 100mm stroke. It functions as a hard stop for end-position tuning and does not hold the load without live air pressure.
