About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X165-10
The AirTAC SAIJ80X165-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 165 mm stroke that can be fine-tuned down by 10 mm, creating a precise 155-165 mm usable travel window. Delivering 2513 N of push force at 0.5 MPa, it handles substantial actuation tasks while allowing on-the-fly end-position calibration.
This model features a carbon steel piston rod and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Because the rear adjuster acts strictly as a mechanical stop to set the travel end, it does not hold the load without live air pressure; for load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X165-10 Is Used
Machine Commissioning
Dial in the exact 155-165 mm end position during setup without adding external mechanical stops.
Product Changeover
Quickly adjust the stroke by up to 10 mm on packaging lines when handling slightly different package sizes.
Clamp Positioning
Set a precise clamping depth using the rear stopper while leveraging 2513 N of thrust at 0.5 MPa.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X165-10 the Right Cylinder?
Choose this 80 mm bore when an application requires more force than a 63 mm cylinder (which provides 1559 N push at 0.5 MPa) but does not need the full 3927 N output of a 100 mm unit. The 10 mm adjustment range is ideal for applications needing slight end-position tuning during commissioning or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder. To match this ISO 15552 interchangeable cylinder, confirm the 165 mm stroke, 10 mm adjustment, PT port, and mounting style.
Supported mounts include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the total stroke is 165 mm, side-load stress is minimal, but external guiding is still recommended if the load is heavy or off-center. The standard carbon steel rod handles standard operating conditions well.
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 SAIJ80X165-10 FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from its nominal 165 mm down to 155 mm. It sets the travel end but does not lock or hold the load without continuous air pressure.
