Airtac SAIJ80 Adjustable Cylinder SAIJ80AX425-10
The AirTAC SAIJ80 Adjustable Cylinder SAIJ80AX425-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 425mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX425-10
The AirTAC SAIJ80X425-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end position. It provides a usable travel window of 415 to 425 mm, letting you dial in the exact stroke during commissioning without adding external stops. This model delivers a robust 2513 N pull force at 0.5 MPa and uses a PT tapered port thread.
Configured with an SUS420J2 stainless steel rod (code A) for improved corrosion resistance, it omits the heavy FB, CA, CB and CR mounting hardware in favor of a streamlined SAIJ set: Basic, FA, LB, TC, FTC, TCM1 and TCM2. Because the 425 mm stroke exceeds the standard 1500 mm limit for this bore, it is manufactured as a non-standard made-to-order unit.

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 SAIJ80AX425-10 Is Used
Machine Changeover
Fine-tune the 415 to 425 mm retract position on the fly when adapting production lines for different product sizes.
Assembly Station Setup
Dial in the exact end-stop during commissioning without physically swapping cylinders or machining external stop blocks.
Long-Stroke Positioning
Handles heavy 2513 N pull loads over a 425 mm travel while allowing 10 mm of micro-adjustment for precise alignment.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX425-10 the Right Cylinder?
Choose this 80 mm bore when you need higher thrust than a 63 mm cylinder (which offers 1402 N pull at 0.5 MPa) but want to avoid the bulk of a 100 mm unit. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers, saving the effort of swapping out a fixed-stroke SAI cylinder. To match an ISO 15552 replacement, specify: 80 mm bore, 425 mm stroke, 10 mm adjustment, PT G3/8 port, and no magnet.
Because this is a 425 mm stroke, the 25 mm rod and M20x1.5 thread will carry more side-load leverage, so an external guide is recommended for unsupported loads. Remember that the rear adjuster acts only as a travel stop to decelerate the end of travel; it does not hold the load without live air. For true load-holding without pressure, use a SAIL locking cylinder or BSAI clamp-lock.
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 SAIJ80AX425-10 FAQ
At the maximum operating pressure of 1.0 MPa, it delivers up to 513 kgf.
A rear external screw acts as a mechanical stop, allowing you to shorten the effective travel from 425 mm down to 415 mm. It only sets the end position; it does not lock the load.
