About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-75S
The AirTAC SAIJ100X80-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and a magnet for CMSE reed or DMSE electronic sensors. It uses PT tapered ports and retains the standard extruded aluminum barrel with sensor grooves on both sides. The rear stopper sets the end position, but it does not lock the load without live air pressure.

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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 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 SAIJ100 Adjustable Cylinder SAIJ100BX80-75S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance from 5 to 80mm on packaging machines that process varying container heights without changing cylinders.
Product Changeover
Quickly reconfigure the stroke window on automated lines during format changes, saving setup time and eliminating external stop hardware.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-75S the Right Cylinder?
The wide 75mm adjustment window is ideal for machines requiring highly variable end-stops or frequent product changeovers, replacing the need for fixed-stroke SAI cylinders and external stops.
For ISO 15552 replacements, match the 100mm bore, 80mm stroke, 75mm adjustment, PT ports, and the -S magnet. Because the stroke is under 300mm, side-load risks are moderate, but the 25mm rod and M20x1.5 thread handle standard loads well. If you need to hold a load without continuous air, use a SAIL lock or BSAI clamp-lock cylinder instead of relying on this adjuster.
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 SAIJ100 Adjustable Cylinder SAIJ100BX80-75S FAQ
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 80mm down to 5mm. This provides a 5-80mm usable window for fine-tuning end positions at commissioning.
At 0.7 MPa, the push force increases to 5497N.
