About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX220-40
The AirTAC SAIJ80X220-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 40 mm. This creates a usable stroke window of 180 to 220 mm, letting you dial in the exact retract end-position during commissioning without adding external stops or swapping the unit. It delivers a robust 2513 N pull force at 0.5 MPa, making it well-suited for heavier positioning tasks.
This SKU is configured with a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes PT tapered ports. The extruded aluminum barrel incorporates sensor grooves on both sides, ready for CMSE reed or DMSE solid-state switches if a magnet is added later. It supports a speed range of 30 to 800 mm/s and utilizes the standard SAIJ mounting set, which includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

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 SAIJ80BX220-40 Is Used
Machine Changeover
Quickly adjust the retract distance by up to 40 mm during product size changes on a packaging line, eliminating the need to physically swap out the entire cylinder.
End-Stop Calibration
Fine-tune the final resting position of a heavy press or clamping mechanism at commissioning, ensuring precise alignment without relying on external mechanical blocks.
Variable Positioning
Set a specific travel window between 180 and 220 mm for automated assembly equipment that requires occasional travel adjustments based on varying component heights.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX220-40 the Right Cylinder?
Choose this 80 mm bore when your application requires higher thrust than a 63 mm cylinder (which provides 1402 N pull at 0.5 MPa) but does not need the full 3681 N pull of a 100 mm unit. The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, whereas a fixed-stroke SAI is preferred when the travel distance is permanently locked. Keep in mind the rear adjuster acts only as a travel stop; it does not hold the load without live air. For fail-safe load holding, consider an SAIL air-released lock or BSAI clamp-lock cylinder.
When replacing an ISO 15552 cylinder, match these exact parameters: 80 mm bore, 220 mm nominal stroke, 40 mm adjustment range, PT G3/8 ports, and the SAIJ mounting interface. Because the stroke is 220 mm, ensure proper guidance to prevent excessive side-load on the 25 mm rod, as long unsupported strokes can cause premature wear.

- ✓ 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 SAIJ80BX220-40 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the 220 mm nominal stroke by up to 40 mm, providing an effective travel range of 180 to 220 mm. It only sets the end position and does not lock the load without continuous air pressure.
