Airtac SAIJ80 Adjustable Cylinder SAIJ80BX220-50
The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX220-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 220mm 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 SAIJ80BX220-50
The AirTAC SAIJ80X220-50 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 220 mm stroke that can be dialed back by up to 50 mm, giving operators a 170-220 mm usable travel window for precise end-position tuning during commissioning.
This configuration features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G3/8 connection. The extruded aluminum barrel includes sensor grooves on both sides, allowing for the direct mounting of AirTAC CMSE reed or DMSE electronic sensors if a magnet is later required. The rear adjuster acts purely as a mechanical stop to set the travel end and 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 SAIJ80BX220-50 Is Used
Product Changeover
Dial in the 170-220 mm travel window on the fly to accommodate different package sizes on a packaging line without changing the cylinder.
Machine Setup
Fine-tune the retract end-position during initial commissioning to achieve exact tooling alignment, avoiding the need for external shims.
Variable End Stops
Use the 50 mm adjustment range to modify the stroke endpoint for flexible manufacturing processes that require varying material push-off distances.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX220-50 the Right Cylinder?
The adjustable 170-220 mm window is ideal for product changeovers on a line, whereas a fixed-stroke SAI cylinder is better suited for applications with rigid, unchanging travel requirements.
Because this cylinder features a 220 mm stroke, it falls below the 300 mm threshold that typically dictates external guidance, but the 25 mm rod diameter still handles moderate side loads well. Remember that the rear adjuster is a travel stop, not a locking device; if the machine loses air pressure, the cylinder will not hold its position. For true load-holding without live air, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead. This SAIJ model supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.
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 SAIJ80BX220-50 FAQ
It can deliver a maximum push force of 513 kgf at 1.0 MPa.
The rear adjuster screw allows you to mechanically shorten the effective stroke from its nominal 220 mm down to 170 mm. This creates a 170-220 mm usable travel window for precise end-position tuning without altering the cylinder mounting.
