About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-50
The AirTAC SAIJ80X195-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 145 to 195 mm, letting you dial in the exact retract position without adding external stops. Driven by a 25 mm carbon steel rod with an M20x1.5 thread, it delivers a robust 4523 N of push force at 0.9 MPa.
This adjustable-stroke model uses a PT tapered G3/8 port and relies on variable air cushions at both ends to manage end-of-stroke deceleration. The extruded aluminum barrel includes sensor grooves on both sides for future CMSE or DMSE switches, while the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-50 Is Used
Machine Changeover
Dial in the retract position from 145 to 195 mm during product size transitions without physically replacing the cylinder or bolting on external stops.
End-Position Tuning
Fine-tune the final end-stop during commissioning to absorb mechanical tolerances, ensuring precise placement of 4523 N push force at 0.9 MPa.
Assembly Line Conveyors
Adjust the stroke window on the fly for varying part sizes on automated lines, utilizing the built-in variable air cushions for smooth deceleration.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X195-50 the Right Cylinder?
Choose this 80 mm bore when your application requires more thrust than a 63 mm cylinder (which provides 2805 N push at 0.9 MPa) but does not warrant the larger 100 mm frame. The 50 mm adjustment range is ideal for product changeovers, allowing you to fine-tune the end position at commissioning rather than swapping a fixed-stroke SAI cylinder.
For stroke lengths of 195 mm, the 25 mm rod handles moderate side loads, but an external guide is recommended for heavy lateral forces. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For fail-safe load holding, consider the SAIL or BSAI series. To match this ISO 15552 footprint exactly, specify an 80 mm bore, 195 mm stroke, 50 mm adjustment, PT port thread, and no magnet.
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 SAIJ80X195-50 FAQ
At 0.9 MPa operating pressure, this 80 mm bore double-acting cylinder generates 4523 N of push force and 2268 N of pull force. It can reach a maximum of 513 kgf at 1.0 MPa.
A rear external screw acts as a stopper to shorten the effective travel, providing a usable window between 145 and 195 mm. This adjuster and the air cushions only set the travel end and deceleration; they do not lock or hold the load without live air pressure.
