About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-20
The AirTAC SAIJ80X110-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 2513N push force at 0.5 MPa and uses a G3/8 port. The integrated rear stopper allows you to trim the 110mm nominal stroke back by up to 20mm, creating a precise 90-110mm usable travel window for exact end-position tuning.
This model features a carbon steel piston rod with an M20x1.5 thread, offering robust resistance to side loads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE or DMSE switches. The rear adjuster acts strictly as a travel stop for deceleration and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-20 Is Used
Machine Changeover
Dial in the 90-110mm travel window during product size changes without physically replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the exact retract distance at machine commissioning to compensate for mechanical tolerances using the rear adjustment screw.
Assembly Clamping
Deliver 3518N of push force at 0.7 MPa for secure clamping, with the flexibility to trim the stroke by up to 20mm for varying part heights.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-20 the Right Cylinder?
Select this 80mm bore cylinder when your application requires 2513N of push force at 0.5 MPa (or 3518N at 0.7 MPa) within a 90-110mm travel window. The 20mm adjustment range is ideal for product changeovers, allowing you to fine-tune the retract end-position at commissioning without swapping the cylinder or adding external stops. If your setup requires holding a load without continuous air pressure, use an AirTAC SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a lock.
For ISO 15552 dimensional interchangeability, match the 80mm bore, 110mm stroke, 20mm adjustment, PT tapered port thread, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Since this is a profile cylinder, it omits tie-rod and rear pivot mounts like FB, CA, CB, and CR.
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 SAIJ80X110-20 FAQ
The rear adjuster screw acts as an external stopper, allowing you to shorten the effective stroke by up to 20mm. This creates a usable travel window of 90-110mm from the 110mm nominal stroke, enabling fine-tuning without changing the cylinder.
At 0.5 MPa operating pressure, the SAIJ80X110-20 provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
