About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX75-10S
The AirTAC SAIJ80X75-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 75 mm nominal travel by up to 10 mm for a precise 65-75 mm usable window. Delivering 2513 N of push force at 0.5 MPa, it handles substantial workloads while utilizing a G3/8 port for optimal flow. The integrated -S magnet enables position feedback via AirTAC CMSE reed or DMSE electronic solid-state sensors seated in the dual-side barrel grooves.
This variant features a SUS304 stainless steel rod (material code B) for superior corrosion resistance in harsh or washdown environments. The rear screw acts purely as a mechanical stop to fine-tune the end position during commissioning without swapping cylinders; it does not lock the load without live air pressure. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX75-10S Is Used
Product Changeovers
Quickly shift the 65-75 mm retract endpoint during packaging format changes without disassembling machine frames or adding external stopper blocks.
Corrosive Environments
Leverage the SUS304 stainless steel rod for pressing or lifting tasks in food processing or chemical areas where moisture would damage standard rods.
Sensor-Verified Positioning
Use the integrated magnet with DMSE electronic sensors to confirm exact end-of-stroke positioning after micro-adjusting the rear stopper screw.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX75-10S the Right Cylinder?
Select this 80 mm bore when an application requires higher thrust than a 63 mm cylinder (which provides 1559 N push at 0.5 MPa) but still needs the exactness of an adjustable end-stop. The 10 mm adjustment window is perfect for product changeovers on a line, letting you shift the retract position without adding external stops. For load-holding without continuous air pressure, this cylinder is insufficient; the rear adjuster only sets travel limits, so you should look at the SAIL or BSAI series instead.
To match this exact ISO 15552 replacement, specify the 80 mm bore, 75 mm stroke, 10 mm adjustment range, PT tapered port threads, and the -S magnet option. The SUS304 rod material is ideal for environments where standard carbon steel rods would pit or rust.
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 SAIJ80BX75-10S 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 achieves a maximum push force of 513 kgf.
The rear adjuster screw allows you to shorten the 75 mm nominal stroke by up to 10 mm, creating a 65-75 mm usable travel window. It acts as a mechanical stop for end-position tuning and is not a lock, meaning the cylinder requires live air to hold a load.
