About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X260-10
The AirTAC SAIJ80X260-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 250 to 260 mm, letting you dial back the nominal 260 mm stroke by up to 10 mm during commissioning. Delivering 2513 N of push force at 0.5 MPa, it handles robust actuation tasks with ease.
This 80 mm bore model uses a G3/8 port and a 25 mm carbon steel rod with an M20x1.5 thread, offering high rigidity against side loads. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster acts purely as a mechanical stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X260-10 Is Used
Machine Changeover
Dial in the 10 mm stroke adjustment during product size transitions to set exact end positions without repositioning the cylinder mount.
Variable End Stops
Fine-tune the 250-260 mm travel window to alter the resting position of conveyor diverters or pushers on the fly.
Assembly Pressing
Leverage the 2513 N push force at 0.5 MPa to seat components securely while adjusting the final 10 mm of travel for different part heights.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X260-10 the Right Cylinder?
Choose this 80 mm bore cylinder when your application requires 2513 N of push force at 0.5 MPa, stepping up from a 63 mm bore that offers 1559 N. The 10 mm adjustable stroke is ideal for fine-tuning the end position on product changeovers without swapping the cylinder or adding external stops. For load-holding without live air pressure, consider the SAIL or BSAI series instead, as the SAIJ adjuster is a stop, not a lock.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 260 mm stroke, 10 mm adjustment, PT tapered port thread, and standard carbon steel rod. Because the stroke is 260 mm, ensure an external guide is used to support long unsupported travel and prevent excessive rod side-loading.
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 SAIJ80X260-10 FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. It can deliver up to 4523 N of push force at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 260 mm down to 250 mm. It is used for fine-tuning end positions at commissioning and is not a lock, meaning it will not hold the load without live air pressure.
