About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X50-50S
The AirTAC SAIJ200X50-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 0-50 mm from its 50 mm nominal stroke. Built with a carbon steel rod and a PT tapered port, it delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa. The -S magnet enables position sensing via CMSE reed or DMSE electronic solid-state switches in the dual-side sensor grooves.
The external rear stopper allows precise end-position tuning at commissioning without adding external stops. This adjuster acts purely as a travel stop to set deceleration alongside the variable air cushions; it does not hold the load without live air. For load-holding without pressure, use SAIL or BSAI types.

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 SAIJ200X50-50S Is Used
Heavy Press Tuning
Dial in the exact 0-50 mm end-position for high-force pressing or forming tasks during initial commissioning without swapping hardware.
Product Changeover
Quickly reset the travel stop for varying product sizes on a heavy-duty line, utilizing the 50 mm adjustment window to adapt the stroke.
Variable End Stops
Fine-tune the retraction point on heavy clamping fixtures, using the rear screw to set the precise travel limit alongside the air cushions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X50-50S the Right Cylinder?
Choosing this 200 mm bore over a smaller neighbor like the 160 mm bore (which pushes 10053 N at 0.5 MPa) is driven by a need for extreme force in a compact 50 mm stroke window. An adjustable stroke is selected here over a fixed SAI when a process requires exact end-position tuning during machine setup or product changeover, offering a 0-50 mm adjustment range.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 50 mm stroke, PT port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the 40 mm rod carries high side-load capacity, it handles robust dynamics, though any long unsupported stroke still requires an external guide.
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 SAIJ200X50-50S FAQ
It can reach up to 3204 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back by up to 50 mm from the nominal stroke, creating a 0-50 mm usable window. It sets the end position and deceleration but does not lock the load without live air pressure.
