About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX115-75
The AirTAC SAIJ80X115-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 115 mm travel back by up to 75 mm. This yields a highly versatile 40 to 115 mm usable travel window, ideal for tuning end positions during commissioning without swapping out the cylinder.
This SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and features a PT tapered G3/8 port. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE solid-state switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The rear screw acts purely as a travel stop for deceleration alongside the adjustable air cushions, not as a load-holding lock.

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 SAIJ80BX115-75 Is Used
Machine Changeover
Dial in the exact end-position for new product sizes on a packaging line by adjusting the rear screw from 40 to 115 mm without changing hardware.
Variable End-Stop Clamping
Apply up to 4523 N of clamping force at 0.9 MPa while fine-tuning the travel distance during initial commissioning to avoid over-travel.
Corrosive Environment Handling
Leverage the SUS304 stainless steel rod for pressing or lifting tasks in wash-down areas where standard carbon steel rods would degrade.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX115-75 the Right Cylinder?
If you need less force, a 63 mm bore provides 1559 N; if you need more, a 100 mm bore offers 3927 N. The SAIJ80X115-75 is selected over a fixed-stroke SAI when machine setups demand frequent product changeovers and variable end-stops without adding external physical stops.
Because this cylinder lacks a -S magnet, it cannot host internal sensors. For load-holding without continuous live air pressure, this plain adjuster cannot hold position; you would need an external pilot-operated check valve or a related AirTAC type like the SAIL pneumatic lock or BSAI clamp-lock. The 25 mm rod and M20x1.5 thread handle high side-load capacity, but any stroke over 300 mm would still require an external guide.
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 SAIJ80BX115-75 FAQ
At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster screw lets you shorten the 115 mm nominal stroke by up to 75 mm, creating a usable travel window of 40 to 115 mm. This stopper only sets the end position and does not lock the load without live air.
