About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX195-20
The AirTAC SAIJ80X195-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 175-195 mm usable travel window. This specific SKU features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads.
The integrated adjusting screw allows you to fine-tune the retract end position at commissioning without swapping out the cylinder or adding external stops. It acts purely as a travel stop to set deceleration, not as a lock, meaning the load will not hold position without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic sensors.

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 SAIJ80BX195-20 Is Used
Variable End-Stop Tuning
Dial in the exact 175-195 mm travel distance during machine commissioning to accommodate minor mechanical clearances without disassembling the line.
Product Changeover
Quickly adjust the retract position on a packaging line when switching to a different product size, saving downtime compared to physically swapping cylinders.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX195-20 the Right Cylinder?
Choose this 80 mm bore when your application requires more thrust than a 63 mm cylinder (1559 N at 0.5 MPa) but less than a 100 mm bore (3927 N). An adjustable stroke is ideal for machine setups requiring variable end stops during product changeovers, whereas a fixed SAI cylinder is better for rigid, unchanging travel limits. Since this is a plain SAIJ without a lock, use a SAIL or BSAI cylinder if you need fail-safe load holding without live air. For ISO 15552 replacement matching, ensure you specify the 195 mm stroke, 20 mm adjustment, G3/8 PT ports, and the SUS304 (B) rod option. Mounting options are limited to the Basic, FA, LB, TC, FTC, TCM1, and TCM2 set.
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 SAIJ80BX195-20 FAQ
The rear adjuster screw lets you trim the nominal 195 mm stroke back by up to 20 mm, providing a usable travel window of 175-195 mm. This stopper sets the end position but does not lock the load without continuous air pressure.
