About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X325-10S
The AirTAC SAIJ80X325-10-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 325 mm stroke that can be fine-tuned backward by up to 10 mm, yielding a 315-325 mm usable travel window. This bore size delivers 3518 N of push force at 0.7 MPa, making it suitable for medium-heavy industrial loads.
Equipped with a -S magnet, it supports position sensing via AirTAC CMSE reed or DMSE electronic solid-state switches mounted in the dual-side sensor grooves. The extruded aluminum barrel uses a G3/8 PT tapered port, and the 25 mm carbon steel rod with an M20x1.5 thread handles high side loads. Because the stroke is 325 mm, an external guide is recommended to prevent rod deflection during extended travel.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X325-10S Is Used
Precision End-Stop Tuning
Dial in the exact 315-325 mm retraction point during machine commissioning to perfect product placement without machining external stoppers.
Automated Assembly Lines
Handles heavy workpiece positioning with 3518 N of push force at 0.7 MPa, using the adjustable end-stop to compensate for mechanical wear over time.
Product Changeover Systems
Quickly adapt a packaging line to different carton lengths by adjusting the 10 mm stroke window rather than replacing the entire cylinder.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X325-10S the Right Cylinder?
Choose this 80 mm bore when a 50 mm bore (offering 1374 N push at 0.5 MPa) lacks the power for your application, but a 100 mm bore (5497 N at 0.7 MPa) is physically oversized. The 10 mm rear adjustment screw is ideal for precision commissioning, allowing you to dial in the exact end-stop without adding external spacers or swapping out a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 325 mm stroke, 10 mm adjustment range, G3/8 PT port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, select a SAIL or BSAI cylinder.
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 SAIJ80X325-10S FAQ
It features a rear adjusting screw that allows you to shorten the effective stroke by up to 10 mm. This creates a 315-325 mm usable travel window, letting you fine-tune the end position at commissioning without changing the cylinder.
At a 0.7 MPa operating pressure, the SAIJ80X325-10-S provides 3518 N of push force and 2268 N of pull force. It can deliver a maximum push force of 4523 N at 0.9 MPa.
