About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X280-100S
The AirTAC SAIJ80X280-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 180 to 280 mm. Fitted with a PT tapered port thread and a carbon steel piston rod, it delivers 2513 N of push force at 0.5 MPa. The integrated -S magnet enables precise position detection using AirTAC CMSE reed and DMSE solid-state sensors.
This adjustable-stroke design allows you to fine-tune the retract end position during commissioning or product changeovers without swapping out the entire cylinder. The rear adjuster functions strictly as a travel stop to set deceleration, not as a load-holding lock; for position holding without live air pressure, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X280-100S Is Used
Product Changeover
Dial in the retract stop by up to 100 mm when switching product sizes on a packaging line, eliminating the need to physically swap cylinders.
Commissioning Calibration
Fine-tune the 180 to 280 mm travel window during machine setup to perfectly align tooling without adding external mechanical stops.
Variable End-Stop Assembly
Adjust the stroke on the fly for assembly stations that press or position components at varying depths within the 280 mm nominal range.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X280-100S the Right Cylinder?
Choose this 80 mm bore when your application requires a robust 2513 N thrust at 0.5 MPa, stepping up from a 63 mm bore that provides 1559 N. The 100 mm adjustment range is ideal for machinery requiring frequent variable end-stop tuning, whereas a fixed-stroke SAI cylinder is better suited for dedicated, single-cycle operations. Mounting options include the SAIJ subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because this model features a 280 mm stroke, the 25 mm rod diameter should be guided externally to prevent excessive side-loading on the piston. To ensure exact ISO 15552 interchangeability, match the 80 mm bore, 280 mm stroke, 100 mm adjustment, PT port thread, and -S magnet configuration to your existing setup.
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 SAIJ80X280-100S FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. It operates at speeds between 30 and 800 mm/s.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective travel from 280 mm down to 180 mm. It sets the end position but does not hold the load without live air pressure.
