About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X450-50
It features a 450mm nominal stroke paired with a rear mechanical adjuster that allows you to fine-tune the effective travel down to 400mm. This 400-450mm adjustable window is ideal for dialing in precise end positions during commissioning without swapping out the entire unit.
Built with a robust 40mm carbon steel rod and M36x2 threading, this model handles significant loads, while the standard PT tapered port threads ensure secure pneumatic connections. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. It supports variable air cushions at both ends to manage kinetic energy, though for load-holding without live air pressure, an external rod lock or a related SAIL lock cylinder is required.

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 SAIJ200X450-50 Is Used
Heavy Press Tuning
Dial in the exact bottoming position of a large forming press within the 400-450mm window to accommodate varying material thicknesses without external stops.
Pallet Diverter Setup
Adjust the retract distance on a heavy-duty pallet diverter to fine-tune the clearance gap during machine commissioning or product changeover.
Large Fixture Clamping
Set precise clamping reach on large machining fixtures, using the rear stopper to vary the end position safely within the 50mm adjustment range.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X450-50 the Right Cylinder?
The rear adjuster acts purely as a travel stop to set the retract position; it is not a locking mechanism, so you must maintain live air to hold a load.
Because this unit features a 450mm stroke, the extended 40mm rod is subject to increased side-loading risks. An external guide should be used to prevent rod binding and premature seal wear. To match this exact ISO 15552 interchangeable footprint, specify the 200mm bore, 450mm stroke, 50mm adjustment, PT port thread, carbon steel rod, and no magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ200X450-50 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 450mm nominal stroke by up to 50mm, creating a 400-450mm usable travel window. It only sets the end position and does not lock the load without live air pressure.
