About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX135-10
The AirTAC SAIJ80X135-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel by up to 10 mm, creating a precise 125-135 mm usable window for commissioning.
This extruded aluminum profile cylinder includes variable air cushions at both ends to manage kinetic energy. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position and cannot hold a load without live air pressure. It supports AirTAC CMSE reed and DMSE electronic sensors via dual side grooves, though this specific SKU is configured without a magnet.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ80BX135-10 Is Used
Changeover Calibration
Dial in the exact 125-135 mm retract distance during product size changeovers on a packaging line without bolting on external stops.
End-Position Trimming
Fine-tune the final resting position of a heavy press tool during machine commissioning to prevent over-travel damage.
Adjustable Ejection
Control the ejection stroke of a machined part on an assembly conveyor, allowing 10 mm of flexibility for varying part dimensions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX135-10 the Right Cylinder?
The 10 mm adjustment range is ideal for dialing in exact end positions during product changeovers without swapping the cylinder or adding external stops. For load-holding without continuous air pressure, integrate an external rod lock or select the SAIL or BSAI series instead.
To match this ISO 15552 interchangeable cylinder for a replacement, verify the 135 mm stroke, 10 mm adjuster, PT port threads, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 25 mm rod and M20x1.5 thread provide substantial rigidity, it handles side loads well, though any stroke approaching 300 mm or beyond still requires 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 SAIJ80BX135-10 FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw acts as a mechanical stop that shortens the nominal 135 mm stroke by up to 10 mm, providing a usable travel window of 125-135 mm. It sets the end position but does not lock the load without live air pressure.
