About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X450-10
It features a carbon steel piston rod and utilizes a PT tapered G3/4 port for robust pneumatic supply. Instead of relying on external stops, this model incorporates a rear adjusting screw that allows you to fine-tune the end position at commissioning.
With a 10 mm adjustment range, this SKU provides a precise 440-450 mm usable travel window, enabling exact positioning without swapping the cylinder. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. It supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and operates at speeds of 30-500 mm/s.

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 SAIJ200X450-10 Is Used
Heavy Pressing
Dial in the exact 440-450 mm travel during product changeovers to apply up to 3204 kgf max thrust without re-engineering machine stops.
Automated Assembly
Fine-tune the end position at commissioning to ensure perfect seating of large components, using the rear stopper to adjust for mechanical tolerances.
Material Handling
Adjust the stroke window on-site to accommodate different pallet sizes on a line, using the 10 mm trim to prevent over-travel damage.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X450-10 the Right Cylinder?
An adjustable stroke is highly beneficial for machine changeovers, allowing you to dial in the exact 440-450 mm travel window on-site rather than machining custom spacers or ordering a fixed-stroke SAI cylinder.
For a 450 mm stroke, the 40 mm diameter carbon steel rod handles high thrust, but long unsupported strokes require an external guide to prevent side-loading damage. Remember that the rear adjuster acts only as a travel stop and cannot hold the load without live air; for true load-holding without pressure, consider an external rod lock, the SAIL series, or BSAI clamp-lock cylinders. This unit is dimensionally interchangeable with 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 SAIJ200X450-10 FAQ
At the maximum operating pressure of 1.0 MPa, the push force reaches 31416 N.
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke from the nominal 450 mm down to 440 mm. This creates a 440-450 mm travel window for fine-tuning end positions without replacing the cylinder.
