About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX350-75
The AirTAC SAIJ80X350-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end-of-travel position. With a nominal 350 mm stroke and a 75 mm adjustment range, it provides a usable travel window of 275 to 350 mm.
This unit is built with a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing for flexible mounting of CMSE reed or DMSE electronic sensors if position feedback is later required. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold 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 SAIJ80BX350-75 Is Used
Machine Changeover
Dial in the exact end position from 275 to 350 mm during product size transitions without swapping the cylinder.
Variable End-Stop Positioning
Set precise retract limits for multi-format assembly lines using the rear 75 mm adjustment screw.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX350-75 the Right Cylinder?
Choose this adjustable-stroke model when a process requires variable end-stops or frequent product changeovers, eliminating the need to physically swap cylinders or add external stopper blocks.
Because the 350 mm stroke is substantial, the 25 mm rod and M20x1.5 thread will still experience leverage forces under high side-loading, so an external guide rail is recommended for optimal performance. This cylinder uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces, omitting the FB, CA, CB, and CR options. It is dimensionally interchangeable per ISO 15552. Remember that the adjuster and air cushions only decelerate the load; for true position holding without live air, select a SAIL or BSAI series cylinder.
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 SAIJ80BX350-75 FAQ
The rear adjuster screw acts as a mechanical stop that lets you trim the effective travel back from the nominal 350 mm down to 275 mm. It is a travel stop only and does not lock or hold the load without continuous air pressure.
