About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X450-50S
The AirTAC SAIJ200X450-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 450 mm stroke that can be fine-tuned backward by up to 50 mm, yielding a precise 400-450 mm usable travel window.
This configuration includes a standard carbon steel piston rod and a magnetic piston (-S) for position sensing. It features PT tapered ports and operates at speeds of 30-500 mm/s. The extruded aluminum barrel incorporates sensor grooves on both sides, allowing you to mount AirTAC CMSE reed or DMSE electronic solid-state switches exactly where needed along the stroke.

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 SAIJ200X450-50S Is Used
Heavy Press Tuning
Dial in the exact 400-450 mm end position for large pressing operations, allowing precise setup changes without swapping out the entire actuator.
Product Size Changeover
Adapt automated machinery to different product heights by simply turning the rear 50 mm stopper screw, minimizing downtime during line format conversions.
Heavy Load Positioning
Shift massive 15708 N loads along a 450 mm path, relying on the 40 mm carbon steel rod while using the adjuster to set the final retraction point.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X450-50S the Right Cylinder?
The integrated 50 mm rear adjuster is ideal for dialing in the exact end-of-stroke position during commissioning or product changeover without adding external mechanical stops.
Because the 450 mm stroke is substantial, the 40 mm diameter carbon steel rod and its M36x2 thread still require an external guide to prevent excessive side-loading on the seals. For mounting, SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding without pressure, consider an external rod lock or the AirTAC SAIL/BSAI series.
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 SAIJ200X450-50S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear external adjuster screw lets you shorten the effective travel from the nominal 450 mm down to 400 mm. This allows you to fine-tune the retraction end position at commissioning without changing the cylinder or adding external stops.
