About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X30-30
The AirTAC SAIJ80X30-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 2513N of push force at 0.5 MPa and provides a usable travel window of 0 to 30 mm, letting you dial in the exact retraction point without external stops.
This 80mm bore unit uses a G3/8 port and a robust 25mm carbon steel rod with an M20x1.5 thread to handle high side loads. The rear screw acts purely as a travel stop for commissioning flexibility, not a lock, so live air is required to hold the load.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X30-30 Is Used
End-Position Tuning
Fine-tune the retraction point within the 0-30mm window during commissioning to achieve precise positioning without machining external stopper blocks.
Machine Changeover
Quickly adapt the effective stroke on automated lines when switching between product sizes, minimizing downtime and avoiding cylinder swaps.
Short-Stroke Clamping
Leverage the 2513N push force for heavy-duty clamping tasks where the exact material thickness varies slightly and requires on-the-fly adjustment.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X30-30 the Right Cylinder?
Choose this 80mm bore when an application requires more force than the 50mm option (982N push at 0.5 MPa) but less bulk than the 100mm class. The adjustable 0-30mm window is perfect for machine setups requiring variable end-stops during product changeovers, replacing the need to swap fixed-stroke SAI cylinders.
For an exact ISO 15552 replacement, match the 80mm bore, 30mm nominal stroke, PT threaded G3/8 port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Because the adjuster only sets the travel end, use a SAIL or BSAI cylinder if you need true load-holding without continuous air pressure.
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 SAIJ80X30-30 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. It can reach a maximum push force of 4523N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 30mm from the nominal 30mm stroke, creating a 0-30mm usable travel window. It functions as a mechanical stop for end-position tuning and is not a locking device.
