About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X150-10S
The AirTAC SAIJ80X150-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 2513N of push force and 2268N of pull force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks. The integrated -S magnet enables position feedback via CMSE reed or DMSE solid-state sensors mounted in the dual-sided extruded barrel grooves.
Equipped with a 10mm adjustment mechanism, this model creates a usable travel window of 140-150mm from its 150mm nominal stroke. This allows operators to fine-tune the retract end position directly at commissioning without adding external stops. The 25mm carbon steel rod and M20x1.5 thread handle high side loads, while the PT tapered G3/8 ports ensure efficient pneumatic flow.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X150-10S Is Used
Machine Changeover
Dial in the 140-150mm retract end-stop during product size changes on a packaging line without swapping out the entire cylinder assembly.
Heavy Assembly Press
Utilize the 2513N push force at 0.5 MPa to seat heavy components, using the 10mm adjuster to perfect the final clamping position.
End-Position Calibration
Fine-tune the exact bottoming position during machine commissioning, absorbing minor mechanical variances with the built-in rear stopper.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X150-10S the Right Cylinder?
Choose this 80mm bore when an application requires over 2200N of pull force at 0.5 MPa, stepping up from a 63mm bore that provides 1402N. The 10mm adjustable stroke is ideal for machines requiring precise end-stop calibration during product changeovers rather than relying on a fixed-stroke SAI cylinder. For an exact ISO 15552 replacement match, specify the 80mm bore, 150mm stroke, 10mm adjustment, PT port thread, and the -S magnet option.
Remember that the rear adjuster functions strictly as a travel stop, not a lock; the cylinder cannot hold a load without live air pressure. For load-holding requirements without continuous air, consider an AirTAC SAIL pneumatic lock, BSAI clamp-lock cylinder, or an external rod lock. Furthermore, while the 25mm rod resists bending, any stroke of 300mm or longer requires an external guide to prevent side-load damage.

- ✓ 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 SAIJ80X150-10S FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 513 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 150mm nominal stroke by up to 10mm, creating a 140-150mm usable travel window. It functions only as a travel stop and does not lock the load without continuous air pressure.
