About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX25-10
The AirTAC SAIJ80X25-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to a 15-25 mm window. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
This specific SKU features a SUS304 stainless steel rod for superior corrosion resistance and ships with PT tapered port threads. The rear adjuster functions strictly as a mechanical stop for end-position tuning during commissioning; it does not lock the load. For true load-holding without live air pressure, consider the SAIL or BSAI series instead.

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 SAIJ80BX25-10 Is Used
Machine Changeover
Dial in precise end-stops during product size changes on a packaging line without bolting on external physical stops.
Short-Stroke Clamping
Provides 2513 N of clamping force at 0.5 MPa, adjustable down to 15 mm for sensitive or variable-thickness parts.
Commissioning Tuning
Fine-tune the exact retract position during initial machine setup to perfect timing and avoid mechanical crashing.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX25-10 the Right Cylinder?
Choose this 80 mm bore when your application demands higher push force than a 63 mm bore (which provides 1559 N at 0.5 MPa), but you do not require the full output of a 100 mm cylinder. The adjustable stroke is ideal for machine changeovers, allowing you to dial in the exact 15-25 mm travel without swapping cylinders or adding external stops. Since this is a short 25 mm stroke, side-loading risks are minimal, but the robust 25 mm rod and M20x1.5 thread handle standard operational stresses well. When specifying a replacement, confirm the 80 mm bore, 25 mm stroke, 10 mm adjustment, PT port, and standard non-magnet configuration.
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 SAIJ80BX25-10 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 25 mm stroke by up to 10 mm, providing a usable travel window of 15-25 mm. It only sets the end position and does not hold the load without live air.
At the maximum 1.0 MPa, it can deliver up to 513 kgf.
