About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-50S
The AirTAC SAIJ200X270-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 270 mm travel by up to 50 mm for a precise 220-270 mm usable window. Built with a robust 40 mm carbon steel rod and a PT tapered port, it delivers massive thrust up to 15708 N at 0.5 MPa and safely handles heavy loads.
Because this configuration includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state sensors housed within the dual-side sensor grooves on the extruded aluminum barrel. The rear stopper screw sets the retract end position for exact product changeovers, but it acts strictly as a travel stop and does not hold the load without live air pressure.

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 SAIJ200X270-50S Is Used
Heavy Press Tuning
Dial in the exact 220-270 mm end position during heavy press commissioning to accommodate varying material thicknesses without swapping cylinders.
Product Size Changeover
Quickly adjust the retract stop on packaging lines when transitioning between different large pallet sizes, ensuring precise mechanical stops.
Large Assembly Stops
Provide a reliable mechanical stop for heavy automotive or industrial assembly lines, fine-tuning the stroke window on the fly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-50S the Right Cylinder?
The adjustable stroke is ideal for fine-tuning end positions during commissioning without adding external stops, whereas a fixed SAI cylinder locks you into one exact dimension. To replace this cylinder, match the 200 mm bore, 270 mm stroke, 50 mm adjuster, PT port thread, and -S magnet.
With a 270 mm stroke, the 40 mm rod provides excellent rigidity, yet long unsupported strokes still require an external guide to prevent excessive side-loading. Remember that the air cushion and rear stopper only decelerate the travel end; for true load-holding without live air, you must use a SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock.
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 SAIJ200X270-50S FAQ
At the maximum operating pressure of 0.9 MPa, the push force reaches 28274 N.
The rear adjuster screw allows you to shorten the 270 mm nominal stroke by up to 50 mm, creating a usable travel window of 220-270 mm. This stopper sets the end position but does not lock the load without continuous air pressure.
