About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X85-40S
The AirTAC SAIJ200X85-40-S is a double-acting ISO 15552 profile cylinder featuring an integrated rear stroke adjuster. This specific configuration includes a magnet for position sensing and uses PT tapered ports. With an 85 mm nominal stroke and a 40 mm adjustment range, you can fine-tune the usable travel window down to 45 mm without adding external stops.
The rear adjuster functions purely as a travel stop for end-position tuning, not a lock, meaning it will not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series. The 40 mm diameter carbon steel rod and M36x2 thread provide high rigidity, while the extruded aluminum barrel features sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic sensors.

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 SAIJ200X85-40S Is Used
Press Fine-Tuning
Dial in the exact 45 to 85 mm travel window during machine commissioning to set precise end positions for heavy pressing tasks.
Product Changeover
Quickly adjust the rear stopper by up to 40 mm to accommodate different product sizes on the line without swapping cylinders.
Heavy End-Stop Adjustment
Set variable end stops for massive 15708N loads, relying on the stopper for travel deceleration rather than position holding.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X85-40S the Right Cylinder?
The adjustable stroke is selected over a fixed SAI cylinder when your application requires variable end-stops or precise commissioning tuning on the fly. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.
When ordering, confirm the bore (200), stroke (85), adjustment (40), port (PT), and magnet (-S). Because this cylinder handles extreme loads, ensure your mounting interface is dimensionally interchangeable per ISO 15552 and that the payload is guided externally to prevent side-loading damage.
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 SAIJ200X85-40S FAQ
It can reach up to 3204 kgf at 1.0 MPa.
The 85 mm nominal stroke can be dialed back by up to 40 mm using the rear adjuster, creating a usable travel window of 45 to 85 mm. This allows you to fine-tune the end position without external stops.
