About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX275-50
The AirTAC SAIJ80X275-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the end position during commissioning. With a nominal 275 mm stroke and a 50 mm adjustment range, the usable travel window spans 225 to 275 mm, letting you dial in the exact retract distance without adding external stops.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and is fitted with PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. Remember that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

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 SAIJ80BX275-50 Is Used
Product Changeover
Quickly reconfigure the retract distance by up to 50 mm during machine setup for different product sizes without replacing the cylinder.
End-Position Tuning
Fine-tune the exact end-of-stroke position at commissioning to perfect timing and avoid mechanical hard stops.
Material Handling
Leverage the 2513 N pull force to move heavy pallets or workpieces, adjusting the travel window to match varying load lengths.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX275-50 the Right Cylinder?
Choose this 80 mm bore when you need more thrust than a 63 mm cylinder (which provides 1402 N pull at 0.5 MPa) but want to avoid the larger footprint and higher air consumption of a 100 mm bore. The adjustable stroke is ideal for product changeovers on a line where the required retract distance varies by up to 50 mm, eliminating the need to physically swap the cylinder for different part sizes. Because the total stroke is 275 mm, ensure an external guide is used to prevent excessive side-loading on the piston rod.
As a dimensionally interchangeable ISO 15552 cylinder, this model uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets, omitting FB, CA, CB, and CR options. It operates at speeds of 30-800 mm/s and carries a standard PT port and SUS304 rod material.

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 SAIJ80BX275-50 FAQ
At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 275 mm nominal stroke anywhere within a 225 to 275 mm window. It decelerates the travel end but does not lock the load without live air pressure.
