About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX25-10S
The AirTAC SAIJ80X25-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 25 mm nominal stroke that can be fine-tuned down by 10 mm, creating a precise 15-25 mm usable travel window for commissioning.
Unlike fixed-stroke variants, this rear adjuster acts as an external mechanical stop to dial in end positions without adding external stops. The adjuster and variable air cushions only decelerate the travel end; they do not hold the load without live air. For position holding without pressure, consider SAIL or BSAI lock variants.

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 SAIJ80BX25-10S Is Used
Machine Setup
Fine-tune the 15-25mm retract stop during commissioning to dial in exact end positions without external shims.
Product Changeover
Quickly adjust the travel window on automated lines when handling slightly different product sizes.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX25-10S the Right Cylinder?
The adjustable 15-25mm window is ideal for product changeovers, letting you trim the retract end by up to 10mm without swapping the cylinder. It uses a PT tapered port and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts. Because the 25mm stroke is short, side-load risks are minimal, but always ensure proper alignment.
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 SAIJ80BX25-10S FAQ
The rear adjuster screw lets you shorten the 25mm nominal stroke by up to 10mm, creating a 15-25mm usable travel window. It acts as a mechanical stop and does not lock the load without live air.
