About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X55-20S
The AirTAC SAIJ200X55-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708N at 0.5MPa. It features a carbon steel rod and a PT tapered port. With a 55mm nominal stroke and a 20mm adjustment range, it provides a usable travel window of 35-55mm for exact end-position tuning.
This adjustable-stop design allows you to dial in the exact retract distance during commissioning without swapping cylinders or adding external stops. It includes a magnet for CMSE and DMSE sensors, and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) compared to fixed variants.

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 SAIJ200X55-20S Is Used
Press Tonnage Setup
Fine-tune the 35-55mm travel window to set precise pressing distances for different material thicknesses on the line.
End-Stop Calibration
Dial in the retract position during commissioning without physically adding external mechanical stops to the fixture.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X55-20S the Right Cylinder?
Choose this 200mm bore when your application requires extreme force, stepping up from a 160mm bore that provides 10053N at 0.5MPa. The 35-55mm adjustable stroke is ideal for setups needing variable end-stops rather than a fixed SAI cylinder. Note that the rear screw acts as a travel stop, not a lock; for holding loads without live air, use an external rod lock or pilot-operated check valve.
Because the stroke is short, side-load risks are minimal, but the 40mm rod and M36x2 thread handle high stress well. To replace this unit, match the 200mm bore, 55mm stroke, 20mm adjustment, PT port, and -S magnet.
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 SAIJ200X55-20S FAQ
The rear adjuster screw lets you shorten the 55mm nominal stroke by up to 20mm, creating a usable travel window of 35-55mm for exact positioning without changing the cylinder.
