About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X650-50
The AirTAC SAIJ200X650-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 600-650mm usable travel window. Built with an extruded aluminum barrel and a robust 40mm carbon steel rod with an M36x2 thread, it delivers massive thrust up to 15708N at 0.5 MPa. This made-to-order 650mm stroke configuration utilizes a PT tapered G3/4 port to handle high flow requirements.
The integrated rear stopper screw allows operators to dial back the end position by up to 50mm during commissioning without swapping hardware. It acts purely as a travel stop and relies on the adjustable air cushions at both ends for deceleration, meaning it will not hold a load without live air pressure. For load-holding applications, consider the SAIL or BSAI series instead.

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 SAIJ200X650-50 Is Used
Heavy Press Tuning
Dial in the exact 600 to 650mm closure position on a large press without fabricating custom spacer blocks for every new die.
Pallet Transfer Stops
Adjust the stopper distance on the fly to handle different pallet lengths on a shared heavy-duty transport line.
Large Fixture Setup
Fine-tune the end-of-stroke clamping position during machine changeover to accommodate varying workpiece widths.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X650-50 the Right Cylinder?
Choose this 200mm bore when 160mm (10053N at 0.5 MPa) cannot generate enough push force for heavy forming or lifting tasks. An adjustable stroke is ideal for production lines running mixed product sizes, allowing variable end-stops without machining new hard stops. When replacing an ISO 15552 cylinder, match the 650mm stroke, 50mm adjustment, PT G3/4 port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 650mm stroke is long and the 40mm rod is unsupported, adding an external guide rail is critical to prevent severe side-loading damage.
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 SAIJ200X650-50 FAQ
The rear adjuster screw acts as a mechanical stop, letting you trim the effective travel back from the 650mm nominal stroke down to 600mm. It sets the end position but does not lock the load without continuous air pressure.
