About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-50
The AirTAC SAIJ80X190-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a nominal 190 mm stroke and a 50 mm adjustment range, it provides a usable travel window of 140 to 190 mm. This allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops.
Built with a SUS304 stainless steel rod and PT tapered port threads, this model handles demanding environments. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Note that the rear adjuster functions as a travel stop to set deceleration, not as a lock; it cannot hold a load without live air pressure. For load-holding applications, consider the SAIL or BSAI series.

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 SAIJ80BX190-50 Is Used
Machine Setup Calibration
Dial in the exact 140-190 mm end-stop during commissioning to perfect positioning without machining external spacers.
Product Size Changeovers
Quickly adapt the retract stroke on packaging lines when switching between different product formats.
Variable End-Stop Actuation
Use the 50 mm adjustment range to compensate for mechanical wear or to tweak the final clamping position dynamically.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX190-50 the Right Cylinder?
Choose this 80 mm bore when 50 mm (982 N at 0.5 MPa) lacks thrust or 100 mm (3927 N at 0.5 MPa) is oversized. The adjustable 140-190 mm travel window is ideal for machine setups requiring variable end-stops or product-size changeovers. Unlike a fixed-stroke SAI cylinder, this SAIJ variant fine-tunes the retract position directly. Since the stroke is under 300 mm, side-load stress on the 25 mm rod is moderate, but external guides remain recommended for heavy lateral loads. To match ISO 15552 replacements, specify bore 80, stroke 190, adjustment 50, PT ports, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set.

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 SAIJ80BX190-50 FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw lets you shorten the effective travel from the 190 mm nominal stroke down to 140 mm. It acts as a mechanical stop to fine-tune the end position and does not lock the load without air pressure.
