About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-100S
The AirTAC SAIJ80X100-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 2513N of push force at 0.5 MPa, making it a robust choice for medium to heavy automation. The integrated -S magnet enables position detection with AirTAC CMSE reed or DMSE electronic solid-state switches.
This specific SKU features a 100mm nominal stroke paired with a 100mm adjustment code, creating a usable travel window of 0-100mm. This maximum adjustment range allows you to dial the effective stroke all the way down to zero without changing the cylinder. The extruded aluminum barrel includes sensor grooves on both sides, and the carbon steel piston rod uses a PT tapered port thread for reliable sealing.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-100S Is Used
Product Changeover
Quickly adapt the cylinder's end-stop to accommodate different package sizes on a packaging line without swapping out hardware.
Commissioning Calibration
Fine-tune the exact end-of-stroke position during machine setup to prevent crushing delicate components, utilizing the full 0-100mm trim range.
Variable End Stops
Provide adjustable mechanical positioning for machining fixtures where the material thickness varies between production runs.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-100S the Right Cylinder?
Choose this 80mm bore when you need significantly more thrust than a 63mm cylinder (which provides 1559N push at 0.5 MPa), but want to avoid the larger footprint and 3927N force of a 100mm bore. The 0-100mm adjustable window is ideal for machines that require flexible end-position tuning during commissioning or frequent product changeovers, replacing the need for multiple fixed-stroke SAI cylinders. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because the stroke is under 300mm, side-load risks are lower, but the 25mm rod diameter still handles lateral stress well. Remember that the rear adjuster acts only as a mechanical stop to set deceleration; it does not hold the load without live air. For true load-holding without pneumatic pressure, consider an external rod lock or the AirTAC SAIL and BSAI series.
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 SAIJ80X100-100S FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjusting screw acts as a mechanical stopper that allows you to trim the effective travel back by up to 100mm. Since the nominal stroke is 100mm, you can adjust the usable window anywhere from 0 to 100mm without replacing the cylinder.
