About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X300-100S
The AirTAC SAIJ200X300-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 200 mm bore, a 300 mm nominal stroke, and a -100 mm adjustment code, yielding a usable travel window of 200 to 300 mm. Built with a carbon steel rod and PT tapered ports, it generates massive thrust up to 21991 N at 0.7 MPa.
Because this is an adjustable-stroke variant rather than a fixed-stroke SAI, you can fine-tune the retract end-position at commissioning without swapping the barrel or bolting on external stops. The -S magnet option enables position sensing via AirTAC CMSE reed and DMSE electronic switches fitted into the dual-side sensor grooves. Note that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

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 SAIJ200X300-100S Is Used
Heavy Machinery Setup
Dial in the 200 to 300 mm travel window during large equipment commissioning to set precise heavy-load retract positions without machining custom spacers.
Variable Product Changeover
Adapt automated press lines to different part sizes instantly by adjusting the rear stopper up to 100 mm, avoiding cylinder replacement delays.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X300-100S the Right Cylinder?
If your process needs less force, stepping down to a 160 mm bore yields 14074 N at the same pressure, while moving up is impossible here as 200 mm is the largest standard SAIJ size. At a 300 mm stroke, the 40 mm diameter carbon steel rod and M36x2 thread provide robust rigidity, but the long unsupported length means an external guide is recommended to prevent side-load damage.
The rear adjuster is strictly a mechanical stop for end-position tuning, not a locking device; it cannot hold loads without continuous air pressure. For load-holding requirements without live air, consider an AirTAC SAIL (air-released lock) or BSAI (clamp-lock) cylinder. This SAIJ200X300-100-S is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: 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 SAIJ200X300-100S FAQ
The rear adjuster screw allows you to shorten the effective travel by up to 100 mm. This creates a usable stroke window of 200 to 300 mm, letting you fine-tune the retract position during setup without replacing the cylinder.
