About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-30S
The AirTAC SAIJ80X130-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 100-130 mm. It delivers a robust 2513 N pull force at 0.5 MPa, making it suitable for moving heavy fixtures. The extruded aluminum barrel features sensor grooves on both sides for straightforward position detection.
Fitted with a carbon steel piston rod and a PT tapered port, this unit includes a magnetic piston (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The rear adjustment screw acts purely as a travel stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-30S Is Used
Machine Changeover
Dial in the 100-130 mm travel window during product size changes to set new end positions rapidly without mechanical rebuilds.
Fixture Positioning
Leverage the 2513 N pull force to move heavy machining fixtures, using the rear screw to fine-tune the clamping distance.
Sorting Diverter
Adjust the retract stop on the fly to handle different package sizes on a sorting line, ensuring precise physical diverts.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-30S the Right Cylinder?
Choose this 80 mm bore when an application requires higher thrust than a 63 mm cylinder (1402 N pull at 0.5 MPa) but does not need the full output of a 100 mm model. The 30 mm adjustment range is ideal for product changeovers, allowing operators to dial in the exact end-stop without swapping cylinders or adding external mechanical stops.
For dimensional replacements, match the 80 mm bore, 130 mm stroke, PT G3/8 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 25 mm rod and M20x1.5 thread handle side loads well, this cylinder is robust, though an external guide is recommended for lateral loads.
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 SAIJ80X130-30S FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of pull force and 3518 N of push force. At the maximum 1.0 MPa operating pressure, it delivers up to 513 kgf.
The rear adjuster screw lets you shorten the effective stroke by up to 30 mm, creating a 100-130 mm usable travel window. It functions as a mechanical stop for end-position tuning and requires live air pressure to hold the load.
