About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-20S
The AirTAC SAIJ80X100-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates an 80-100mm usable travel window from its 100mm nominal stroke.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing with CMSE reed or DMSE electronic switches. It features PT tapered port threads (G3/8) and variable air cushions at both ends to manage impact deceleration.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-20S Is Used
Machine Changeover
Dial in the exact 80-100mm end-stop during format size changes on a packaging line without replacing hardware.
Assembly Positioning
Fine-tune the retract stroke to press components accurately, absorbing minor variations in part tolerances.
Conveyor Diverter
Adjust the travel distance of a diverting gate on the fly to handle different package widths on a single belt.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-20S the Right Cylinder?
Choose this adjustable model when your assembly requires precise end-position tuning at commissioning or during product changeovers without swapping the physical cylinder. If your application needs less force, stepping down to a 63mm bore yields 1402N of pull force at 0.5 MPa; conversely, moving to a 100mm bore provides 3681N of pull force.
Because the rear screw acts only as a travel stop and the cushions manage deceleration, this cylinder will not hold a load without live air pressure. For drop-prevention or fail-safe holding, consider the SAIL or BSAI series. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552.
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 SAIJ80BX100-20S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 20mm, providing a usable travel window of 80-100mm. This allows you to set the exact retract end-position during installation without adding external stops.
The operating speed range is 30-800 mm/s, controlled by variable air cushions at both ends.
