About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-20S
The AirTAC SAIJ100X80-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 3927N of push force at 0.5 MPa. By integrating a magnet for position sensing, it supports AirTAC CMSE reed and DMSE electronic sensors mounted directly into the dual-side barrel grooves. The carbon steel piston rod features an M20x1.5 thread, providing a robust interface for high-load attachments.
This specific SKU features an 80mm nominal stroke paired with a 20mm rear adjustment screw, creating a usable 60-80mm travel window. This built-in adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning; it does not hold the load without live air pressure. For applications requiring position holding without continuous pneumatic pressure, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-20S Is Used
Machine Setup Changeover
Dial in the 60-80mm travel window during product size changeovers to set new retract end positions without disassembling the line.
Variable End-Stop Tuning
Fine-tune the final retract position within a 20mm range during commissioning to perfect part seating or clamping depth.
High-Force Positioning
Leverage the 3927N push force at 0.5 MPa to shift heavy jigs or platens, using the rear screw to trim the exact stroke.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X80-20S the Right Cylinder?
Choose this 100mm bore cylinder when your application requires substantial thrust (3927N push at 0.5 MPa) alongside precise end-position tuning. If you need less force, stepping down to an 80mm bore yields 2513N, whereas upgrading to a 125mm bore provides 6136N. The adjustable 60-80mm travel window is ideal for machine setups requiring variable end stops or product changeovers without swapping the cylinder or adding external stopper blocks.
As a dimensionally interchangeable ISO 15552 profile cylinder, it matches standard mounting footprints using a reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Ensure your setup specifies PT tapered port threads, the -S magnet option for CMSE/DMSE sensors, and the exact 100mm bore, 80mm stroke, and 20mm adjustment code when seeking a direct ISO 15552 replacement.
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 SAIJ100 Adjustable Cylinder SAIJ100X80-20S FAQ
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective stroke by up to 20mm. This creates a usable travel window of 60-80mm, allowing you to fine-tune the retract end position at commissioning without adding external stops.
At 0.5 MPa operating pressure, it provides 3927N of push force and 3681N of pull force. If your system runs at 0.7 MPa, the push force increases to 5497N.
