About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX375-100S
The AirTAC SAIJ80X375-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The built-in adjuster allows you to trim the effective travel, creating a 275-375mm usable stroke window from the 375mm nominal length.
Because the stroke exceeds 300mm, the 25mm rod diameter and M20x1.5 thread provide substantial support, though an external guide is still recommended for long unsupported loads. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet option enables precise position detection using AirTAC CMSE reed or DMSE electronic solid-state switches.

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 SAIJ80BX375-100S Is Used
Variable End-Stop Tuning
Dial in the exact 275 to 375mm travel distance during commissioning to accommodate different material lengths without adding external stopper blocks.
Product Changeover
Quickly adjust the retract position on a packaging line to handle varying box sizes, using the 100mm adjustment range for rapid setup.
Machine Setup Calibration
Fine-tune the end-of-stroke position to prevent crushing delicate components, relying on the rear screw to set the precise travel limit.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX375-100S the Right Cylinder?
Choose this adjustable model when your machine setup requires variable end-stops or frequent product changeovers without swapping the cylinder. If you need less force, stepping down to a 63mm bore yields 2805N at 0.9 MPa; for higher thrust, a 100mm bore provides 7068N. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
Remember that the rear adjuster acts only as a travel stop and deceleration aid, not as a lock. The cylinder cannot hold a load without live air pressure. For true fail-safe load holding, consider the SAIL air-released lock, the BSAI clamp-lock, or an external rod lock.
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 SAIJ80BX375-100S FAQ
It operates efficiently within a speed range of 30-800 mm/s.
The rear adjuster screw lets you shorten the 375mm nominal stroke by up to 100mm, creating a 275-375mm usable travel window. It functions as a mechanical stop to fine-tune end positions without changing the cylinder.
