About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-30S
The AirTAC SAIJ80X160-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa, making it well-suited for medium-to-heavy actuation tasks. The integrated magnet (-S) enables direct position sensing using AirTAC CMSE reed or DMSE electronic solid-state switches mounted into the dual sensor grooves on the extruded aluminum barrel.
This specific SKU provides a nominal 160 mm stroke that can be fine-tuned down by up to 30 mm, creating a precise 130-160 mm usable travel window. This built-in adjuster acts purely as a mechanical stop to dial in the retract end position during commissioning; it is not a locking device and will not hold a load without live air pressure. The carbon steel piston rod features an M20x1.5 thread, providing a robust interface for mounting attachments.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-30S Is Used
Machine Changeover
Dial in the 130-160 mm retract position during product size changes without adding external stopper blocks to the machine frame.
End-Stop Calibration
Fine-tune the final resting position of heavy 2513 N loads at commissioning to achieve precise mechanical alignment.
Variable Diverting
Adjust the stroke length on the fly for pneumatic diverters that must accommodate different package sizes on a single line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-30S the Right Cylinder?
Select this 80 mm bore cylinder when your application requires 2513 N of thrust at 0.5 MPa but demands exact end-position tuning without swapping physical components. If you need less force, stepping down to a 63 mm bore yields 1559 N; if you need more, a 100 mm bore provides 3927 N. The adjustable 130-160 mm travel window is ideal for product changeovers on a line, replacing the need for fixed-stroke SAI cylinders when setup dimensions vary slightly. Remember that the rear adjuster only sets the travel end and does not function as a brake—true load-holding without pneumatic pressure requires a SAIL pneumatic lock or BSAI clamp-lock cylinder.
To match this exact ISO 15552 interchangeable footprint, specify an 80 mm bore, 160 mm nominal stroke, and a 30 mm adjustment range. The unit features PT tapered port threads (G3/8), a standard carbon steel rod, and an integrated magnet (-S) for CMSE / DMSE sensors. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

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 SAIJ80X160-30S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw allows you to shorten the 160 mm nominal stroke by up to 30 mm, providing a usable travel window of 130-160 mm. It functions as a mechanical stop for end-position tuning and is not a load-holding lock.
