About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-75S
The AirTAC SAIJ80X190-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 190 mm travel back by up to 75 mm, creating a flexible 115-190 mm usable window. The extruded aluminum barrel includes sensor grooves on both sides, and because this is an -S variant, it carries a magnet ready for AirTAC CMSE reed and DMSE electronic solid-state switches.
This unit is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance, paired with PT tapered port threads (G3/8). The rear adjuster acts purely as a mechanical stop to fine-tune the retract end-position during commissioning or product changeovers without adding external stops. It is not a locking device and will not hold a load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series instead.

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 SAIJ80BX190-75S Is Used
Product Changeover Dials
Quickly reconfigure the retract distance from 115 mm to 190 mm on packaging lines when switching to a different container size, eliminating the need to physically swap cylinder bodies.
End-Stop Commissioning
Fine-tune the exact end-of-stroke position during machine setup without machining custom external stopper blocks, ensuring perfect alignment before locking down the sequence.
Corrosive-Resistant Forming
Leverage the SUS304 stainless steel rod to push or pull tooling in humid or washdown manufacturing environments where standard carbon steel rods would degrade.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-75S the Right Cylinder?
The generous 75 mm adjustment range is ideal for machinery that handles varying product sizes, allowing operators to dial in the exact retract distance on the fly rather than swapping out physical spacers. When replacing an ISO 15552 cylinder, match the 190 mm stroke, 75 mm adjustment code, G3/8 PT ports, and the -S magnet requirement.
Because the total stroke can reach up to 190 mm, ensure your payload is guided externally to prevent excessive side-loading on the 25 mm rod. Remember that the rear adjuster screw and the variable air cushions at both ends manage deceleration, but a plain SAIJ cylinder cannot maintain its position if air pressure drops. The mounting hardware is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR styles found in some other lines.
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 SAIJ80BX190-75S FAQ
If you step up to 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw lets you mechanically shorten the 190 mm nominal stroke by up to 75 mm, giving you an effective travel window of 115 to 190 mm. This allows you to set precise end-positions during commissioning without changing the cylinder.
