About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X105-20S
The AirTAC SAIJ80X105-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 85 to 105 mm. Generating 2513 N of push force at 0.5 MPa, it is designed for applications requiring precise end-position tuning during commissioning without swapping out the physical cylinder. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet enables position detection with AirTAC CMSE reed or DMSE solid-state switches.
This model uses a 25 mm carbon steel piston rod with an M20x1.5 thread, offering robust resistance to side loads. The rear adjuster functions strictly as a mechanical stop to set the retraction end position, working in tandem with variable air cushions at both ends to decelerate the load. It is not a locking mechanism, so if your process requires position holding without live air pressure, you should consider the SAIL or BSAI series instead.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X105-20S Is Used
Machine Changeover
Dial in the retraction end-stop by up to 20 mm during product size changes without replacing the cylinder or re-engineering the fixture.
Variable End-Stop
Set the exact 85 to 105 mm travel window during commissioning to perfect the resting position of linked mechanisms.
Assembly Calibration
Fine-tune the tooling approach distance on assembly lines, using the rear screw to absorb mechanical tolerances.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X105-20S the Right Cylinder?
Select this 80 mm bore cylinder when your machine setup requires a 2513 N push force at 0.5 MPa and a nominal 105 mm travel that might need trimming by up to 20 mm. If your application demands less force, stepping down to a 63 mm bore yields 1559 N, while moving up to a 100 mm bore provides 3927 N. Choose this adjustable-stroke SAIJ variant over a fixed-stroke SAI when you need a variable end-stop to accommodate product changeovers or fine-tune the final position without adding external stops.
To match this exact configuration for an ISO 15552 replacement, specify the 80 mm bore, 105 mm stroke, 20 mm adjustment range, PT tapered port threads, and the -S magnet option. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories. Although the 25 mm rod handles side loads well, always ensure proper guiding for any offset loads to prevent premature seal wear.
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 SAIJ80X105-20S FAQ
At a 0.5 MPa operating pressure, this 80 mm bore cylinder generates 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 acts as a mechanical stop that lets you trim the effective travel back from the 105 mm nominal stroke down to 85 mm. It sets the end position and deceleration point, but it does not lock or hold the load without continuous air pressure.
