About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-50
The AirTAC SAIJ80X200-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window from 150 to 200 mm. The barrel is extruded aluminum with sensor grooves on both sides, and the rod is constructed from SUS304 stainless steel for superior corrosion resistance.
This model uses PT tapered port threads and a G3/8 air supply connection. The rear adjuster acts purely as a mechanical stop to dial in the end position during commissioning or product changeover without swapping the cylinder. It is important to note that this adjuster, along with the variable air cushions at both ends, only decelerates the travel; it does not lock or hold the load without live air pressure.

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 SAIJ80BX200-50 Is Used
Machine Changeover
Dial in the 150-200 mm travel window during product size changes without physically swapping out the entire cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the exact retract end-point during commissioning to perfect the seating of heavy components, utilizing the 25 mm SUS304 rod for durability.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-50 the Right Cylinder?
Choose this 80 mm bore when your application requires significant thrust, such as 4523 N at 0.9 MPa, but you need the flexibility to trim the stroke by up to 50 mm. If you need less force, stepping down to a 63 mm bore provides 2805 N at 0.9 MPa, while stepping up to a 100 mm bore yields 7068 N. The adjustable stroke is ideal for machine setups requiring variable end stops, whereas a fixed SAI cylinder is better for dedicated, single-purpose stations.
Because this is a plain double-acting cylinder, it will not hold its position or load without live air. For load-holding requirements, consider the SAIL or BSAI series. When replacing an ISO 15552 cylinder, match the 80 mm bore, 200 mm stroke, 50 mm adjustment, PT G3/8 port, and your desired mounting set (Basic, FA, LB, TC, FTC, TCM1, or TCM2). For any stroke of 200 mm or more, ensure external guides are used to manage side loads on the 25 mm rod.

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 SAIJ80BX200-50 FAQ
At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster acts as a mechanical stop that allows you to shorten the 200 mm nominal stroke by up to 50 mm, creating a usable travel window of 150 to 200 mm. It only sets the end position and does not lock the load without live air.
