About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-20
The AirTAC SAIJ80X200-20 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 200 mm stroke with an external screw mechanism that allows you to dial back the travel by up to 20 mm, creating a precise 180-200 mm usable window. This fine-tuning capability at commissioning eliminates the need to swap cylinders or bolt on external stops during product changeovers.
The rod is constructed from SUS304 stainless steel (code B) for superior corrosion resistance, and the G3/8 PT tapered ports ensure a tight, reliable pneumatic connection. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic sensors.

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 SAIJ80BX200-20 Is Used
Machine Changeover Setup
Dial in the exact 180-200 mm end position during product size transitions without physically replacing the cylinder or adding external stopper blocks.
Variable End-Stop Positioning
Fine-tune the retract stroke on automated machining fixtures to accommodate varying material thicknesses or tooling depths at commissioning.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-20 the Right Cylinder?
The SAIJ80X200-20 is chosen over a fixed-stroke SAI when you need precise end-position tuning without swapping components. It supports a speed range of 30-800 mm/s and accepts the SAIJ mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets.
Because the 200 mm stroke exceeds the 300 mm side-load threshold? No, at 200 mm it is below the strict guide threshold, but the 25 mm rod and M20x1.5 thread still handle moderate side loads well; for long unsupported strokes, always use an external guide. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air—use a SAIL or BSAI cylinder for true load-holding without pressure.
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 SAIJ80BX200-20 FAQ
It features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the effective stroke by up to 20 mm. This provides a usable travel window of 180-200 mm. The adjuster only sets the travel end and does not lock or hold the load without live air pressure.
At 0.9 MPa, the push force increases to 4523 N. The maximum thrust is 513 kgf at 1.0 MPa.
