About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-30
The AirTAC SAIJ200X350-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 320 to 350 mm.
This 200 mm bore unit uses a robust 40 mm carbon steel rod with an M36x2 thread, paired with 50 mm variable air cushions at both ends to manage high kinetic energy. The extruded aluminum barrel includes sensor grooves on both sides, and the rear stopper acts purely as a travel limiter—it does not hold the load without live air pressure.

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 SAIJ200X350-30 Is Used
Heavy Press Tuning
Dial in the exact 320 to 350 mm end-of-stroke position during heavy press setup without adding external mechanical stops.
Product Changeover
Adjust the travel window on the fly to accommodate different large product sizes moving down a heavy-duty conveyor line.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-30 the Right Cylinder?
Select this 200 mm bore model when your application requires extreme force (up to 15708 N at 0.5 MPa) and on-the-fly stroke trimming without swapping out the cylinder. Because the 350 mm stroke is substantial, an external guide is recommended to prevent rod side-loading and premature wear.
The rear adjuster allows up to 30 mm of stroke reduction, but it functions only as a mechanical stop, not a lock. For load-holding without continuous air pressure, consider the AirTAC SAIL or BSAI series. This cylinder uses a PT tapered G3/4 port, supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, and operates at 30-500 mm/s.
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 SAIJ200X350-30 FAQ
At 0.9 MPa, the push force increases to 28274 N.
The rear adjuster screw allows you to shorten the nominal 350 mm stroke by up to 30 mm, creating a usable travel window of 320 to 350 mm. This stopper only limits the travel end and does not lock or hold the load without live air pressure.
