Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-75S
The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX200-75S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-75S
The AirTAC SAIJ80X200-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 125 to 200 mm for precise end-position tuning during commissioning.
This variant includes a magnet for position sensing and uses PT tapered ports sized at G3/8. The rear adjustment screw acts purely as a mechanical stop to dial in the stroke without swapping cylinders, and it does not lock 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 SAIJ80BX200-75S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance from 125 to 200 mm on packaging machines without physically changing the cylinder or adding external stopper blocks.
Product Size Changeover
Rapidly adjust the stroke endpoint on a production line to accommodate varying material widths or lengths during product family transitions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-75S the Right Cylinder?
The 75 mm adjustment range is ideal for machinery that frequently processes different product sizes, allowing operators to vary the end-stop rapidly instead of adding external spacers. To match this cylinder for an ISO 15552 replacement, specify the 80 mm bore, 200 mm stroke, PT port thread, SUS304 rod, and the -S magnet.
Because the nominal stroke is 200 mm, standard mounting support is generally sufficient, though the 25 mm rod diameter handles side loads well. Remember that the rear adjuster only sets the travel end; for dead-load holding without live air, select an AirTAC SAIL or BSAI series cylinder instead.
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 SAIJ80BX200-75S FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to mechanically shorten the effective stroke from its 200 mm nominal length down to as little as 125 mm, giving a 75 mm tuning window. The adjuster functions only as a travel stop and does not hold the load without continuous air pressure.
