About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX195-50
The AirTAC SAIJ80X195-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 145-195 mm usable travel window.
This adjustable model uses a PT tapered port thread and G3/8 fluid connections. The extruded aluminum barrel includes sensor grooves on both sides, and the rear stopper screw allows you to fine-tune the retract end position during commissioning without adding external stops.

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 SAIJ80BX195-50 Is Used
Machine Setup Tuning
Dial in the exact 145-195 mm travel end-stop during initial commissioning to perfect product seating without machining custom spacers.
Product Size Changeover
Quickly retract the stroke by up to 50 mm when switching the production line to a shorter package format, minimizing downtime.
Variable End Positioning
Use the rear stopper screw to precisely set the retract distance for multi-stage pressing or testing operations on a single fixture.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX195-50 the Right Cylinder?
The 50 mm adjustment range is perfect for product changeovers, letting you dial in the exact end-stop on the fly instead of swapping out a fixed-stroke SAI cylinder.
Because the nominal 195 mm stroke is under 300 mm, side-load risks are moderate, but the 25 mm rod thread still requires external guiding for heavy lateral loads. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, use a SAIL or BSAI cylinder. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
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 SAIJ80BX195-50 FAQ
It operates at speeds between 30 and 800 mm/s.
The rear adjuster screw lets you shorten the nominal 195 mm stroke by up to 50 mm, creating a usable travel window of 145 to 195 mm. This stopper only sets the end position and does not lock the load without continuous air pressure.
