About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X260-100S
The AirTAC SAIJ80X260-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the nominal 260 mm travel back by up to 100 mm, creating a 160-260 mm usable window for precise end-position tuning. Built with a carbon steel rod and a PT tapered G3/8 port, it delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback.
Equipped with a magnet for sensors, this unit supports AirTAC CMSE reed switches and DMSE solid-state electronics. The rear adjuster acts purely as a mechanical stop to set the retract position during commissioning or product changeover; it does not lock the load without live air. For applications requiring position holding without pneumatic pressure, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X260-100S Is Used
Machine Changeover
Dial in the exact retract distance from 160 to 260 mm during product size transitions without replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the final end-of-stroke position during machine commissioning to compensate for mechanical tolerances or sensor placement variations.
Variable Diverter Stops
Adjust the physical stop position on the fly to handle different package sizes on a conveyor line, using the rear screw to set the exact travel limit.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X260-100S the Right Cylinder?
Choose this 80 mm bore when 50 mm (982 N push at 0.5 MPa) is too weak and 100 mm (3927 N) is oversized. An adjustable stroke is preferred over a fixed SAI cylinder when you need to fine-tune the retract end-point on the fly without swapping hardware or adding external stops. When replacing an ISO 15552 cylinder, match the 80 mm bore, 260 mm stroke, 100 mm adjuster, PT G3/8 port, and the -S magnet requirement. Because the 260 mm stroke is over 300 mm? No, but for any stroke approaching this length with heavy loads, ensure an external guide supports the 25 mm rod to prevent side-load damage.
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 SAIJ80X260-100S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 4523 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 260 mm nominal stroke by up to 100 mm, giving a usable travel window of 160 to 260 mm. It only sets the end position and does not hold the load without live air pressure.
