Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-10S
The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX190-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 190mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-10S
It features a SUS304 stainless steel rod and a PT tapered port thread. The built-in rear stopper allows you to dial back the nominal 190mm travel, creating a precise 180-190mm usable window for fine end-position tuning during commissioning without adding external stops.
This adjustable-stroke design is ideal for product changeovers on a shared machine base. The extruded aluminum barrel includes sensor grooves on both sides, and because this SKU includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a mechanical travel stop to set deceleration, not as a lock; for load-holding without live air, a SAIL or BSAI variant is required.

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 SAIJ80BX190-10S Is Used
Machine Setup Tuning
Dial in the exact 180-190mm end-position during commissioning to perfect a pressing operation without swapping out the entire cylinder.
Product Changeover
Quickly adjust the rear stopper by up to 10mm to accommodate slightly different product lengths on a shared conveyor line.
Precision End-Stop
Use the rear mechanical stop to set a hard travel limit for a machining fixture, ensuring repeatable positioning independent of air cushion drift.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-10S the Right Cylinder?
The 10mm adjustment range is selected when you need minor end-stop corrections rather than a wide variable travel window, letting you fine-tune the 180-190mm stroke at setup while retaining the standard ISO 15552 mounting footprint.
When replacing a cylinder, match the 80mm bore, 190mm nominal stroke, 10mm adjustment, PT port thread, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. The 25mm rod and M20x1.5 thread handle high side loads well, though any stroke exceeding 300mm still requires an external guide.
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 SAIJ80BX190-10S FAQ
The maximum operating pressure is 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that shortens the effective travel. For this model, the nominal 190mm stroke can be trimmed back by up to 10mm, giving a usable travel window of 180-190mm for fine-tuning without moving the cylinder mounts.
