About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X15-10S
The AirTAC SAIJ80X15-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features an 80 mm bore generating 2513 N of push force at 0.5 MPa, paired with a 15 mm nominal stroke that can be fine-tuned down by up to 10 mm, creating a precise 5-15 mm usable travel window. This integrated adjuster allows you to dial in the exact end position during commissioning without adding external stops.
This variant includes a magnet for position sensing and uses a standard carbon steel piston rod with PT tapered ports. It carries adjustable air cushions at both ends to decelerate the load smoothly. Remember that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X15-10S Is Used
Micro-Positioning Stops
Dial in the 5-15 mm travel window to set exact clamping depths on precision parts without machining custom spacers.
Machine Changeover
Quickly adjust the rear stopper screw during product size changeovers to accommodate varying workpiece thicknesses on the fly.
High-Force Short-Stroke Press
Leverage the 2513 N push force at 0.5 MPa for short-stroke pressing or holding operations where stroke length varies slightly per batch.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X15-10S the Right Cylinder?
Select this 80 mm bore model when an application demands high force in a very compact footprint with micro-travel adjustability. If the 5-15 mm window is too tight or the 2513 N push force at 0.5 MPa exceeds your requirement, stepping down to a 63 mm bore yields 1559 N, whereas moving up to a 100 mm bore provides 3927 N. The adjustable stroke is chosen over a fixed SAI cylinder when you need variable end-stops for product changeovers.
To replace an ISO 15552 cylinder, match the 80 mm bore, 15 mm stroke, 10 mm adjustment, G3/8 port, and the -S magnet. The SAIJ utilizes a specific mounting subset including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. Although the 25 mm rod handles side loads well, always verify guiding on external rails.
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 SAIJ80X15-10S FAQ
The rear adjuster screw allows you to shorten the 15 mm nominal stroke by up to 10 mm, providing a usable travel window of 5-15 mm. It functions as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
At 0.5 MPa operating pressure, the SAIJ80X15-10-S generates 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, it achieves a maximum push force of 513 kgf.
