About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X425-20
The AirTAC SAIJ200X425-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 405 to 425 mm usable travel window. Built with a robust 40 mm carbon steel rod and PT G3/4 ports, it delivers massive thrust up to 28274 N at 0.9 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
This adjustable model lets you fine-tune the retract end position at commissioning without swapping the cylinder or adding external stops. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster acts only 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 SAIJ200X425-20 Is Used
Heavy Pressing
Dial in the exact 405-425 mm end position for high-force pressing and forming tasks during machine setup.
Product Changeover
Quickly adjust the retract stop to accommodate different large-scale product sizes on the same line.
Assembly Line Tuning
Fine-tune the travel end during commissioning to perfect the stroke without changing the cylinder.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X425-20 the Right Cylinder?
Choose this 200 mm bore when you need maximum thrust, as stepping down to a 160 mm bore yields 18095 N at 0.9 MPa. The adjustable 20 mm window is ideal for product changeovers requiring variable end stops. For load-holding without continuous air, select a SAIL or BSAI model instead. This SAIJ cylinder is dimensionally interchangeable per ISO 15552 and uses a PT tapered port thread. Because the 425 mm stroke is long, an external guide is recommended to manage side loads on the unsupported rod.
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 SAIJ200X425-20 FAQ
The rear stopper screw lets you trim the 425 mm nominal stroke back by up to 20 mm, creating a 405-425 mm travel window.
