About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X425-40S
The AirTAC SAIJ200X425-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers immense thrust, pushing with 15708 N and pulling 15080 N at 0.5 MPa, peaking at 3204 kgf at 1.0 MPa. The integrated -S magnet enables position feedback via CMSE reed and DMSE electronic sensors fitted into the dual-side barrel grooves.
This specific SKU provides a 425 mm nominal stroke that can be dialed back by up to 40 mm, yielding a precise 385-425 mm usable travel window. The PT tapered ports and G3/4 thread size match the heavy-duty 200 mm bore class, while the carbon steel rod offers standard industrial durability.

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 SAIJ200X425-40S Is Used
Heavy Press Tuning
Dial in the exact 385-425 mm retract position during heavy press commissioning without machining new stopper blocks.
Product Changeover
Quickly adjust the end stop for varying pallet sizes on a high-thrust conveyor line, utilizing the 3204 kgf maximum capacity.
Large Assembly Jigs
Secure massive components in automated assembly jigs, using the M36x2 rod thread and PT ports for robust, high-flow actuation.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X425-40S the Right Cylinder?
Select this 200 mm bore when an application demands maximum pneumatic force and on-the-fly end-position tuning. If the full 425 mm stroke is excessive for a new product layout, the rear stopper saves you from swapping the cylinder or adding external mechanical stops.
Because the 425 mm stroke is long, the 40 mm rod diameter and M36x2 thread provide necessary rigidity, though an external guide is recommended to manage side loads on unsupported extensions. The rear adjuster acts solely as a travel stop and cannot hold the load without live air pressure; for true fail-safe holding, consider the SAIL or BSAI series. This profile cylinder uses the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting set, omitting FB, CA, CB, and CR options.
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 SAIJ200X425-40S FAQ
The operating speed range for this 200 mm bore is 30-500 mm/s.
The rear adjuster screw lets you mechanically shorten the effective stroke from 425 mm down to 385 mm. This stopper only sets the travel end and does not lock the load without live air pressure.
