About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X450-30S
The AirTAC SAIJ200X450-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a massive 15708N of push force at 0.5MPa, utilizing a robust 40mm carbon steel rod and M36x2 thread. Equipped with a -S magnet, it integrates seamlessly with AirTAC CMSE reed and DMSE solid-state sensors via the dual-side barrel grooves.
This specific SKU provides a usable travel window of 420 to 450mm, allowing you to dial back the nominal stroke by up to 30mm. The extruded aluminum barrel design omits tie-rods, and the rear stopper screw lets you fine-tune the retract end position during commissioning without adding external physical stops.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X450-30S Is Used
Heavy Press Operations
Provides up to 15708N of thrust at 0.5MPa for heavy assembly presses, with the 30mm stroke adjuster allowing precise bottoming-out tuning for different material thicknesses.
Multi-Product Changeover
Dial in the 420-450mm travel window during line changeovers to accommodate varying part sizes without physically swapping out the entire cylinder or adding external stopper blocks.
Large Fixture Positioning
Moves large automated welding or machining fixtures into place, using the integrated -S magnet and DMSE sensors to confirm retracted and extended positions across a long 450mm stroke.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X450-30S the Right Cylinder?
Choose this 200mm bore when 160mm (10053N at 0.5MPa) cannot generate enough push force for heavy pressing or clamping. The adjustable 30mm window is ideal for product changeovers where exact end-of-stroke positioning varies slightly between fixtures. Because the 450mm stroke is substantial, an external guide is highly recommended to manage side-load stresses on the 40mm rod.
Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure. For fail-safe load holding, select the SAIL or BSAI series instead. This SAIJ model uses PT tapered ports and supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), making it dimensionally interchangeable with other ISO 15552 cylinders.
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 SAIJ200X450-30S FAQ
At a 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can deliver up to 3204 kgf at its maximum 1.0MPa pressure rating.
The rear adjuster screw allows you to shorten the 450mm nominal stroke by up to 30mm, creating a 420-450mm usable travel window. This stopper only decelerates and sets the end position; it does not lock the load without continuous air pressure.
