About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX220-100
The AirTAC SAIJ80X220-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 220 mm stroke that can be dialed back by up to 100 mm, yielding a usable travel window of 120 to 220 mm. This wide adjustment range allows operators to fine-tune the retract end-position during commissioning or product changeover without swapping out the cylinder or adding external stops.
This variant features a SUS304 stainless steel rod (code B) for superior corrosion resistance in harsh environments. It uses PT tapered ports sized G3/8 and relies on a 25 mm rod with an M20x1.5 thread, providing a robust interface that handles higher side loads than smaller bores. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. Remember that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for true load-holding, 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 SAIJ80BX220-100 Is Used
Variable Product Changeover
Ideal for packaging lines where the rear 100 mm adjuster allows rapid resetting of the retract end-stop to accommodate varying package lengths without replacing the cylinder.
Machine Commissioning
Perfect for dialing in the exact 120 to 220 mm travel window during final machine setup, ensuring precise end-position tuning without adding external mechanical stops.
Corrosive Forming Press
The SUS304 stainless steel rod handles high-force pressing tasks up to 2513 N at 0.5 MPa while resisting moisture and corrosion in washdown manufacturing environments.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX220-100 the Right Cylinder?
If you need less force, stepping down to a 63 mm bore drops the 0.5 MPa push force to 1559 N; stepping up to a 100 mm bore raises it to 3927 N. The 100 mm adjustment range is ideal for machines processing variable product sizes, allowing rapid end-stop tuning without mechanical rework. Because the 220 mm stroke is relatively long, an external guide is recommended to prevent excessive rod side-loading and premature seal wear.
As a dimensionally interchangeable ISO 15552 cylinder, this model matches standard footprint dimensions and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It operates at speeds of 30-800 mm/s and uses PT port threads. Without an -S magnet suffix, this specific configuration does not support internal CMSE or DMSE sensors.

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 SAIJ80BX220-100 FAQ
At the maximum rated pressure of 1.0 MPa, the push force reaches 513 kgf.
The rear external adjusting screw acts as a mechanical stopper that can shorten the effective stroke by up to 100 mm. This creates a usable travel window of 120 to 220 mm from the 220 mm nominal stroke, allowing fine-tuning of the retract position without replacing the cylinder.
