About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX195-50S
The AirTAC SAIJ80X195-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 50 mm. This yields a usable stroke window of 145 to 195 mm, enabling precise end-position tuning at commissioning without swapping the barrel or adding external stops.
Built with a SUS304 stainless steel rod for superior corrosion resistance, this model includes a magnet for position sensing with CMSE reed or DMSE electronic switches. The extruded aluminum barrel provides dual sensor grooves on both sides, and the PT tapered port threads ensure a tight, reliable pneumatic connection.

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 SAIJ80BX195-50S Is Used
Machine Changeover
Dial in the 145-195 mm retract distance during product-size changeovers without physically swapping cylinders or adding external stopper blocks.
Washdown Automation
The SUS304 stainless steel rod and adjustable stroke make it suitable for packaging or handling equipment requiring corrosion resistance and variable end stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX195-50S the Right Cylinder?
The 50 mm adjustment range is ideal for product-size changeovers on a line, allowing operators to dial in the exact retract distance on the fly. Unlike a fixed-stroke SAI cylinder, this adjustable variant provides a mechanical stop to fine-tune the end position.
For ISO 15552 interchangeability, match the 80 mm bore, 195 mm stroke, 50 mm adjustment, PT port thread, and the -S magnet requirement. The mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Note that the rear adjuster acts solely as a travel stop; it does not hold the load without live air. For fail-safe load holding, consider the SAIL or BSAI series instead.
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 SAIJ80BX195-50S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 195 mm nominal stroke by up to 50 mm, providing a usable travel window of 145 to 195 mm. It functions as a travel stop and does not lock the load without live air pressure.
