About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX115-50
The AirTAC SAIJ80X115-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to shorten the effective travel without external stops. The built-in adjustment mechanism provides a usable travel window of 65-115 mm, enabling precise end-position tuning during commissioning.
This model features a SUS304 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. It is important to note that the rear adjuster acts purely as a travel stop to decelerate the end of stroke; it does not lock or 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 SAIJ80BX115-50 Is Used
Product Changeover
Dial in the 65-115mm travel window during product size transitions to set new end positions without physically replacing the cylinder.
Machine Setup
Fine-tune the retract end-stop during initial machine commissioning to perfectly dial in the stroke length for precise indexing.
Variable End Stops
Use the rear adjuster to set exact retraction depths for multi-format clamping operations on a single fixture.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX115-50 the Right Cylinder?
The 50mm adjustment range is ideal for accommodating product size changes on a production line without physically swapping the cylinder. If your application requires less force, stepping down to a 63mm bore yields 1559N at 0.5 MPa.
For load-holding requirements without continuous air pressure, this cylinder is not a locking device; you should instead look to the SAIL or BSAI series. Because this model utilizes a 25mm rod and M20x1.5 rod thread, it handles side loads well, but any stroke over 300mm would still require an external guide. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.
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 SAIJ80BX115-50 FAQ
The maximum push force reaches 513 kgf at 1.0 MPa.
The rear adjuster allows you to trim the nominal 115mm stroke back by up to 50mm, creating a usable travel window of 65-115mm. It functions as a mechanical stop and does not lock the load.
