About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X550-100
The AirTAC SAIJ200X550-100 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty positioning. By integrating a rear mechanical stopper, this model provides an effective adjustable travel window of 450 to 550 mm.
This adjustable variant omits the FB, CA, CB, and CR mounts, utilizing a focused set of ISO 15552 interfaces (Basic, FA, LB, TC, FTC, TCM1, TCM2) to simplify high-force integration. The extruded aluminum barrel features sensor grooves on both sides for CMSE reed and DMSE solid-state switches. Equipped with a carbon steel rod and PT tapered port threads, it handles rigorous operating cycles while allowing precise end-position tuning without external stops.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 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 SAIJ200 Adjustable Cylinder SAIJ200X550-100 Is Used
Heavy Machinery Setup
Fine-tune the 450-550 mm travel window during heavy press commissioning to achieve precise end-position alignment without machining custom external stoppers.
Product Size Changeover
Quickly adapt the retract stroke by up to 100 mm on automated assembly lines when switching between large product variants, minimizing downtime.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X550-100 the Right Cylinder?
The 100 mm rear adjuster allows operators to dial in the exact end-of-stroke position during commissioning or product changeover, avoiding the need to physically swap cylinders or bolt on external stopper blocks. For holding loads without live air pressure, this cylinder is insufficient; the rear adjuster acts only as a travel stop, so consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder for fail-safe load holding.
When replacing an ISO 15552 unit, match the 200 mm bore, 550 mm stroke, 100 mm adjustment range, PT port threads, and the specific mounting interface. Because the 550 mm stroke is substantial, the 40 mm diameter carbon steel rod and M36x2 thread still require external guidance to prevent side-loading damage on the unsupported rod extension.
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 SAIJ200 Adjustable Cylinder SAIJ200X550-100 FAQ
At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 550 mm nominal stroke down to 450 mm. This creates a 100 mm tuning window for precise end-positioning at commissioning, but it does not lock or hold the load without continuous air pressure.
