About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-40
The AirTAC SAIJ80X130-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 90 to 130 mm, letting you dial back the nominal stroke by up to 40 mm during commissioning. Operating at 0.9 MPa, it delivers a robust push force of 4523 N, making it well-suited for medium to heavy-duty positioning tasks.
This model incorporates a 25 mm carbon steel piston rod with an M20x1.5 thread, offering excellent rigidity and side-load resistance. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches, though this specific SKU is supplied without a magnet. The rear adjuster acts purely as a travel stop to fine-tune the end position without needing external stops.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-40 Is Used
Machine Changeover
Dial in the 90-130 mm travel window precisely when switching production lines to accommodate minor variations in product dimensions without swapping cylinders.
End-Position Tuning
Fine-tune the retract stop during setup to perfect the seating of components, eliminating the need to fabricate and install custom external spacers.
Variable Stops
Adjust the stroke end-point on the fly for packaging lines handling different carton sizes, ensuring precise positioning without mechanical rebuilds.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-40 the Right Cylinder?
Choose this 80 mm bore when the 50 mm class (1374 N at 0.5 MPa) is insufficient but you want to avoid the bulk of a 100 mm body. The 40 mm adjustment range is ideal for product changeovers where the exact end-of-stroke varies slightly between batches. If your process requires the cylinder to hold a load statically without live air pressure, note that this adjuster is only a stop; you should instead select an AirTAC SAIL or BSAI series. For replacement, verify the 130 mm stroke, 40 mm adjuster, PT G3/8 port, and the required mounting set (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
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 SAIJ80X130-40 FAQ
At an operating pressure of 0.9 MPa, this 80 mm bore cylinder generates a push force of 4523 N and a pull force of 2268 N. At 0.5 MPa, it provides 2513 N of push force.
The rear adjuster screw allows you to shorten the effective stroke by up to 40 mm. For this 130 mm stroke model, it creates a usable travel window between 90 and 130 mm, enabling fine-tuning of the end position without replacing the cylinder.
