About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX170-100S
It features a SUS304 stainless steel rod and a PT tapered port. By integrating an external adjusting screw, this model provides a usable travel window of 70 to 170 mm, allowing you to dial back the nominal stroke by up to 100 mm during commissioning without swapping the cylinder.
This adjustable-stroke design eliminates the need to bolt on external stops for product changeovers. The extruded aluminum barrel includes sensor grooves on both sides, and with the built-in magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches. The rear screw acts purely as a travel stop to fine-tune the end position, so live air is still required to hold the load.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX170-100S Is Used
Product Changeover
Quickly adapt the cylinder's effective stroke from 70 to 170 mm on packaging lines handling varying box sizes, avoiding physical hardware swaps.
Machine Setup
Fine-tune the exact end-of-stroke position during initial commissioning to perfect pressing or forming forces without adding external stopper blocks.
Variable End Stops
Manage diverse material lengths on a single conveyor system by adjusting the rear stopper screw to set precise, repeatable retraction limits.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX170-100S the Right Cylinder?
The SUS304 rod offers high corrosion resistance, and the robust M20x1.5 rod thread handles significant side loads, though any stroke approaching 300 mm or beyond still necessitates an external guide.
When specifying an ISO 15552 replacement, match the 80 mm bore, 170 mm stroke, 100 mm adjustment, PT port thread, and the -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the rear adjuster only sets the travel end and is not a locking device, use a SAIL or BSAI cylinder if you need to hold a load without continuous air pressure.
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 SAIJ80BX170-100S FAQ
At a maximum 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster screw allows you to trim the effective travel back by up to 100 mm from the 170 mm nominal stroke, creating a usable window of 70 to 170 mm. The screw functions as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
