About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-75S
The AirTAC SAIJ80X100-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical stroke adjuster. It features a 25 mm SUS304 stainless steel rod and a PT tapered port. With a nominal 100 mm stroke and a 75 mm adjustment range, it provides a highly flexible usable travel window of 25-100 mm for precise commissioning.
The integrated magnet (-S) supports CMSE reed and DMSE electronic sensors mounted in the dual-side barrel grooves. The rear adjuster acts purely as a travel stop to fine-tune end positions without adding external stops, though it does not hold the load without live air pressure.

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 SAIJ80BX100-75S Is Used
Product Changeover
Dial the stroke down from 100 mm to 25 mm instantly on the rear screw when switching to a shorter package size, eliminating the need to swap cylinders or reposition external stopper blocks.
End-Position Tuning
Fine-tune the retract end-position during machine commissioning to perfect the pressing or clamping depth without changing the fixed 100 mm barrel length.
Variable End Stops
Provide a customizable travel window for automated assembly lines that need to test and adjust the exact reach of a 25 mm SUS304 stainless steel rod across different jigs.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX100-75S the Right Cylinder?
Choose this 80 mm bore when an application requires more thrust than the 63 mm version (1559 N at 0.5 MPa) but less bulk than the 100 mm class. The 75 mm adjustment range is ideal for machines running multiple product sizes, allowing you to dial back the stroke from 100 mm down to 25 mm during changeovers instead of physically swapping the cylinder.
For exact ISO 15552 dimensional replacement, match the 80 mm bore, 100 mm stroke, 75 mm adjuster, PT port thread, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, CR). Because the adjuster is a stop and not a lock, use SAIL or BSAI cylinders if the load must be held without continuous air pressure.
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 SAIJ80BX100-75S FAQ
The rear adjuster screw lets you mechanically shorten the effective stroke by up to 75 mm. This creates a usable travel window of 25-100 mm, allowing you to set the exact retract end-position during commissioning without replacing the cylinder.
At 0.5 MPa operating pressure, the push force is 2513 N and the pull force is 2268 N. If pressure is increased to 0.9 MPa, the push force reaches 4523 N.
