About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-100S
The AirTAC SAIJ200X270-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 170 to 270 mm, enabling precise end-position tuning at commissioning without swapping the barrel or adding external stops.
This unit includes a standard carbon steel rod and a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides. The rear adjuster acts as a travel stop to set the retract end-position; it does not lock or hold the load without live air pressure. For load-holding without supply pressure, consider an external rod lock or related AirTAC types like SAIL or BSAI.

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 SAIJ200X270-100S Is Used
Heavy Press Tuning
Fine-tune the 170-270 mm travel window during machine commissioning to set exact pressing depths on thick metal components without machining custom spacers.
Product Changeover Stops
Adjust the retract end-position by up to 100 mm on a packaging line to accommodate different carton lengths rapidly, avoiding complete cylinder swaps.
Large Fixture Positioning
Dial in the exact clamping location for oversized automotive molds, using the rear stopper to compensate for mechanical tolerance stack-ups on the assembly line.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-100S the Right Cylinder?
The 100 mm adjustment range is ideal for machinery that undergoes frequent product-size changeovers, allowing operators to dial back the stroke by up to 100 mm rather than machining new hard stops. This cylinder uses a PT tapered port thread and supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.
Because the 270 mm stroke exceeds 300 mm when fully extended with certain mountings, long unsupported strokes require an external guide to prevent excessive side loading on the 40 mm rod. The operating speed for this bore is 30-500 mm/s. When replacing an ISO 15552 cylinder, verify the 200 mm bore, 270 mm nominal stroke, 100 mm adjustment, PT port, mounting interface, and the -S magnet requirement.
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 SAIJ200X270-100S FAQ
It can deliver up to 3204 kgf at its maximum 1.0 MPa pressure rating.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from the nominal 270 mm down to 170 mm. This adjuster only sets the travel end and does not lock or hold the load without live air pressure.
