Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-75
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 130mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-75
The AirTAC SAIJ80X130-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 130 mm travel back by up to 75 mm. This creates a highly flexible 55 to 130 mm usable window, letting you dial in exact end positions during commissioning without swapping out the physical unit. It delivers 2513 N of push thrust at 0.5 MPa, scaling up to 4523 N at 0.9 MPa for demanding operations.
The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. Because this is an 80 mm bore, it uses a G3/8 port and a robust M20x1.5 rod thread, which handles greater side loads than smaller bores. The rear screw acts purely as a mechanical stop to set deceleration and travel length, meaning it will not hold the load if air pressure drops.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-75 Is Used
Variable Product Changeovers
Quickly shift the effective stroke between 55 and 130 mm on a packaging conveyor to handle different carton sizes without changing the cylinder.
Machine Setup Tuning
Fine-tune the retract end position during initial commissioning to perfectly time a pressing operation, avoiding the cost of custom spacers.
Adjustable Ejector Stops
Act as an adjustable mechanical stop on an ejection line, allowing the 80 mm bore to deliver 2513 N of force at varying depths based on part geometry.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-75 the Right Cylinder?
Choose this 80 mm bore when a 50 mm bore (offering 982 N push at 0.5 MPa) is too weak, but a 100 mm bore (3927 N at 0.5 MPa) is physically oversized. The 75 mm adjustment range is ideal for packaging lines running multiple product sizes, allowing operators to reposition the end stop rapidly during changeovers rather than bolting on external spacers. To replace an ISO 15552 cylinder, match the 130 mm stroke, 75 mm adjuster, PT tapered port threads, and your required mounting bracket from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
If your machine requires true fail-safe load holding without live air, note that this adjuster is a stop, not a lock. You would need to specify an AirTAC SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock instead. For this 130 mm stroke, side loads are moderate, but always guide the rod to prevent binding.
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 SAIJ80X130-75 FAQ
A rear external screw acts as a mechanical stopper, allowing you to shorten the 130 mm nominal stroke by up to 75 mm. This provides a usable travel window of 55 to 130 mm, which can be fine-tuned during machine setup or product changeovers without replacing the cylinder.
At 0.5 MPa operating pressure, the SAIJ80X130-75 provides 2513 N of push thrust and 2268 N of pull thrust. At 0.9 MPa, the push force increases to 4523 N.
