About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX80-10
The AirTAC SAIJ80X80-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window down to 70-80 mm without swapping components. Built with a durable SUS304 stainless steel rod, it delivers a robust 2513 N push force at 0.5 MPa, making it ideal for heavy-duty positioning tasks.
This model uses a PT tapered port thread and excludes the FB, CA, CB, and CR mounting options found on some standard cylinders, utilizing a focused set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to easily add CMSE reed or DMSE electronic sensors for position feedback.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX80-10 Is Used
Precision End-Stop Tuning
Dial in the exact clamping position within a 70-80 mm window during machine commissioning to avoid machining hard stops.
Product Changeover
Quickly adjust the retract distance by up to 10 mm on a packaging line when switching to a different sized carton.
Heavy-Duty Forming
Leverage the 2513 N push force at 0.5 MPa for pressing or forming operations that require precise depth control.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX80-10 the Right Cylinder?
Choose this 80 mm bore when you need more thrust than a 63 mm cylinder (which provides 1559 N at 0.5 MPa) but want to avoid the larger footprint of a 100 mm bore. The 10 mm adjustment range is perfect for dialing in exact end positions during commissioning or product changeovers, whereas a fixed SAI cylinder locks you into a single 80 mm stop. If your machine requires holding a load without continuous air pressure, note that this rear adjuster acts only as a travel stop; you should integrate an external rod lock or look at the SAIL or BSAI series instead. For any application exceeding 300 mm of stroke, always use an external guide to support the rod and prevent excessive side-loading.
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 SAIJ80BX80-10 FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke from the nominal 80 mm down to 70 mm. It only sets the travel end and does not lock the load without live air pressure.
