About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-50
The AirTAC SAIJ200X325-50 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, built for heavy-duty positioning.
This bore 200 unit uses a robust 40 mm carbon steel rod with an M36x2 thread, paired with 50 mm air cushions at both ends to manage heavy kinetic energy. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ200X325-50 Is Used
Heavy Press Tuning
Dial in the exact 275-325 mm end-position for large material presses during setup, avoiding the need to swap cylinders for different material thicknesses.
Pallet Changeover
Quickly adjust the retract stop for varying pallet sizes on a 200 mm bore actuator pushing 15708 N, ensuring precise stops without external mechanical stops.
Large Assembly Jigs
Fine-tune the stroke window on heavy assembly lines to accommodate product variants, using the rear screw to set the exact 275 mm minimum travel.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-50 the Right Cylinder?
The adjustable-stroke design is selected over a fixed SAI cylinder when you need to fine-tune the retract end-position during machine setup or product changeover without adding external stops. Because the 325 mm stroke is over 300 mm, an external guide is recommended to handle side loads on the long unsupported rod.
This cylinder is dimensionally interchangeable per ISO 15552. To match this replacement, specify: 200 mm bore, 325 mm stroke, 50 mm adjustment, PT port thread, standard mounting, and no magnet (-S). Note that the rear adjuster is a travel stop, not a lock; for load-holding without live air pressure, use an SAIL or BSAI cylinder.
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 SAIJ200X325-50 FAQ
It can deliver up to 3204 kgf at its maximum 1.0 MPa pressure.
The rear adjuster screw lets you shorten the 325 mm nominal stroke by up to 50 mm, creating a 275-325 mm usable travel window. It acts as a mechanical stop to fine-tune the end position and does not lock or hold the load without live air pressure.
