About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX80-10S
The AirTAC SAIJ80X80-10-S 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 port. The built-in rear stopper provides a 70 to 80mm usable travel window, letting you dial in the exact retract position without swapping hardware.
This variant includes a magnet (-S) for position sensing alongside an SUS420J2 stainless steel rod (code A) for superior corrosion resistance. It retains the standard extruded aluminum barrel with dual sensor grooves, supporting AirTAC CMSE reed and DMSE electronic switches. The adjuster acts purely as a travel stop, meaning the load requires continuous live air pressure to remain held.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX80-10S Is Used
Precision Position Tuning
Dial in the exact 70-80mm retract distance during machine commissioning to perfect part seating without machining new hard stops.
Product Changeover
Quickly adjust the end-of-stroke position by up to 10mm on packaging lines when switching between slightly different product sizes.
High-Force Clamping
Leverage the 2513N push force at 0.5 MPa to secure heavy workpieces, using the rear stopper to set the precise clamp depth.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX80-10S the Right Cylinder?
Choose this 80mm bore when an application requires higher thrust than a 63mm cylinder (1559N at 0.5 MPa) but has spatial constraints preventing a 100mm bore. The 10mm adjustment range is ideal for fine-tuning end stops during machine commissioning or product changeovers, offering flexibility that a fixed-stroke SAI cylinder cannot. To match this ISO 15552 replacement exactly, specify the 80mm bore, 80mm stroke, PT tapered port thread, and the -S magnet option.
Because the stroke is 80mm, side-load risks are minimal, though the substantial 25mm rod and M20x1.5 thread naturally handle higher bending loads. If your process demands true load-holding without constant air pressure, this cylinder will not suffice; you should instead select an AirTAC SAIL or BSAI locking cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ80AX80-10S 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 achieves a push force of 4523N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 80mm stroke by up to 10mm. This creates a 70-80mm usable travel window for fine-tuning the retract end position without replacing the cylinder.
