About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-100S
The AirTAC SAIJ80X200-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 200 mm stroke but features a 100 mm adjustment range, yielding a usable travel window of 100 to 200 mm. This wide window allows you to fine-tune the retract end-position at commissioning or during product changeover without swapping the cylinder or adding external stops. Delivering 2268 N of pull force at 0.5 MPa, it handles robust actuation tasks.
This SKU is built with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing with AirTAC CMSE reed and DMSE electronic switches. The extruded aluminum barrel features sensor grooves on both sides. The rear adjuster acts purely as a mechanical stop to set the travel end, so it does not hold the load without live air pressure.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |

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 SAIJ80BX200-100S Is Used
Variable End-Stop Tuning
Dial in the exact retract position from 100 to 200 mm during machine commissioning to perfect end-of-stroke positioning without adding external mechanical stops.
Product Size Changeover
Quickly adapt automated lines to different product lengths by adjusting the rear stopper screw up to 100 mm, reducing setup time between production batches.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX200-100S the Right Cylinder?
Choose this 80 mm bore when you need substantial thrust, such as the 2268 N pull force at 0.5 MPa, combined with a highly flexible 100 to 200 mm travel window. If your application requires less force, stepping down to a 63 mm bore provides 1402 N of pull force at 0.5 MPa. Conversely, if your setup demands more power, a 100 mm bore yields 3681 N of pull force at 0.5 MPa. The wide 100 mm adjustment range is ideal for machines processing multiple product sizes, whereas a fixed-stroke SAI cylinder suits single-size runs.
For an exact ISO 15552 replacement match, specify: 80 mm bore, 200 mm stroke, 100 mm adjustment, PT tapered port threads, and a magnet for sensors (-S). Note that SAIJ supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR. Because the stroke is 200 mm, ensure external guiding is used to manage side loads on the 25 mm rod. For load-holding without live pressure, select a SAIL or BSAI cylinder instead of relying on the adjuster.
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 SAIJ80BX200-100S FAQ
At the maximum operating pressure of 1.0 MPa, it delivers a maximum push force of 513 kgf.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back from the 200 mm nominal stroke down to 100 mm. This creates a 100 to 200 mm usable window for fine-tuning the end position at setup, but it does not lock or hold the load without continuous air pressure.
