About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX195-75
The AirTAC SAIJ80X195-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits an effective usable travel window of 120 to 195 mm. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This adjustable variant allows technicians to dial in the exact retract end-position during commissioning or product changeovers without adding external stops or swapping the cylinder. The 75 mm adjustment range is governed by a rear stopper screw, which sets the travel limit but does not lock the load in place without live air pressure. It supports a standard speed range of 30 to 800 mm/s and uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ80BX195-75 Is Used
Machine Changeover
Quickly adapt the retract end-position for different product sizes on a packaging line using the 75 mm adjustment window, avoiding physical cylinder swaps.
Commissioning Calibration
Fine-tune the exact end-of-stroke stop during initial machine setup to perfect timing and mechanical positioning without adding external stopper blocks.
Variable End-Stop Forming
Adjust the effective travel from 120 to 195 mm on the fly to accommodate varying material thicknesses in an industrial pressing or clamping station.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX195-75 the Right Cylinder?
If your process demands less force, stepping down to the 63 mm bore yields 1559 N at 0.5 MPa, while moving up to the 100 mm bore provides 3927 N for heavier loads. The SUS304 rod material offers high corrosion resistance for wet or chemically exposed environments.
Because the nominal stroke is 195 mm, an external guide is recommended to manage side loads and prevent rod deflection. Remember that the rear adjuster acts purely as a mechanical stop; it will not hold the load if air pressure drops. For true fail-safe load holding, consider the SAIL pneumatic lock series or an external pilot-operated check valve. This cylinder is dimensionally interchangeable per ISO 15552 mounting interfaces.
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 SAIJ80BX195-75 FAQ
It features a rear stopper screw that lets you mechanically shorten the nominal 195 mm stroke by up to 75 mm, providing an adjustable travel window of 120 to 195 mm. This allows precise end-position tuning without changing the cylinder, though the screw acts as a stop and not a lock.
If pressure is increased to 0.7 MPa, the push force rises to 3518 N.
