About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-75
The AirTAC SAIJ80X100-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 25-100 mm usable travel window. It delivers 2513 N of push force at 0.5 MPa and uses a G3/8 port. The extruded aluminum barrel includes sensor grooves on both sides.
This 80 mm bore model uses a 25 mm carbon steel rod with an M20x1.5 thread, providing robust resistance to side loads. The rear adjuster acts purely as a mechanical stop for fine-tuning end positions at commissioning; it is not a lock and will not hold a load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-75 Is Used
End-Position Tuning
Fine-tune the retract end position during commissioning using the rear screw, trimming the stroke anywhere within the 25-100 mm window to perfect machine timing.
Product Changeover
Quickly adapt the cylinder travel on a packaging line when switching to a different product size, avoiding the need to physically swap out the entire actuator.
Variable End Stops
Set precise mechanical stops for varying material lengths without adding external stopper blocks to your fixture, keeping the ISO 15552 footprint clean.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-75 the Right Cylinder?
Choose this adjustable model over a fixed-stroke SAI when your machine setup requires variable end-stops or frequent product-size changeovers, allowing you to dial back the 100 mm stroke by up to 75 mm without swapping hardware. If your application needs less force, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa.
For an ISO 15552 replacement, match the 80 mm bore, 100 mm stroke, PT tapered port threads, and standard carbon steel rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, CR). For load-holding without live pressure, consider the SAIL or BSAI series instead.
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 SAIJ80X100-75 FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 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 lets you shorten the nominal 100 mm stroke by up to 75 mm, creating a usable travel window of 25-100 mm. This adjuster functions as a mechanical stop for end-position tuning and does not lock or hold the load without continuous air pressure.
