About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X210-10S
The AirTAC SAIJ80X210-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 200-210 mm, allowing you to dial back the nominal 210 mm stroke by up to 10 mm. Operating at 0.5 MPa, it generates 2513 N of push force and 2268 N of pull force, making it well-suited for medium-to-heavy actuation tasks.
Equipped with a magnet for position sensing, this version integrates seamlessly with AirTAC CMSE reed and DMSE solid-state switches fitted into the dual-side sensor grooves. The extruded aluminum barrel uses a G3/8 PT port, and the 25 mm carbon steel rod with an M20x1.5 thread offers robust resistance to side loads. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X210-10S Is Used
Precision Changeover Stops
Dial in the exact 200-210 mm end-stop during machine setup to accommodate new product lengths without changing hardware.
Adjustable Diversion
Fine-tune the retract position on sorting gates to handle varying package sizes on the fly.
Assembly Calibration
Trim the final 10 mm of travel to perfect part seating pressure during automated assembly line commissioning.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X210-10S the Right Cylinder?
Choose this adjustable-stroke model when your assembly requires precise end-position tuning during commissioning or product changeovers, avoiding the need to swap cylinders or add external stops. If your application demands less force, stepping down to a 63 mm bore yields 1559 N push at 0.5 MPa; for heavier loads, a 100 mm bore provides 3927 N.
For a drop-in ISO 15552 replacement, match the 80 mm bore, 210 mm stroke, 10 mm adjustment range, G3/8 PT port, and the -S magnet option. Because the stroke is 210 mm, ensure adequate external guiding to prevent rod side-loading. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series.
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 SAIJ80X210-10S FAQ
At a standard 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 adjuster screw lets you shorten the effective travel from the nominal 210 mm down to 200 mm. This allows precise end-position tuning at commissioning without external stops, though it functions only as a travel stop and does not lock the load.
