Airtac SAIJ200 Adjustable Cylinder SAIJ200X45-30
The AirTAC SAIJ200 Adjustable Cylinder SAIJ200X45-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 45mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X45-30
The AirTAC SAIJ200X45-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits precise end-position tuning. It provides a usable travel window of 15-45 mm, letting you dial back the 45 mm nominal stroke by up to 30 mm during commissioning without adding external stops.
This heavy-duty actuator integrates variable air cushions at both ends to manage kinetic energy, but the rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure. It runs at speeds of 30-500 mm/s and supports a focused set of ISO 15552 mounting interfaces including Basic, FA, LB, TC, FTC, TCM1, and TCM2. The extruded aluminum barrel includes sensor grooves on both sides for adding CMSE or DMSE switches if needed.

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 SAIJ200X45-30 Is Used
Heavy-Duty Press Tuning
Dial in the exact 15-45 mm travel window during machine commissioning to achieve precise pressing force without physically swapping large actuators.
Product Size Changeover
Quickly adapt the end-stop position on automated lines when product dimensions change, using the 30 mm rear adjuster to modify the stroke on the fly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X45-30 the Right Cylinder?
Choose this 200 mm bore when your application requires maximum thrust, as stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N. The adjustable 15-45 mm travel window is ideal for product changeovers on a line, allowing you to fine-tune the retract end-stop on the fly instead of swapping out a fixed-stroke SAI cylinder. Because the stroke is short, side-load risks are minimal, but always ensure the load is guided on longer strokes.
Remember that a plain SAIJ cylinder does not function as a lock; the rear adjuster and air cushions only set the travel end and deceleration. If your setup requires true load-holding without continuous live air pressure, consider an external rod lock or pilot-operated check valve, or switch to related AirTAC types like the SAIL or BSAI. This specific configuration features PT tapered ports and a standard carbon steel rod without a magnet.

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 SAIJ200X45-30 FAQ
The rear adjuster screw allows you to shorten the 45 mm nominal stroke by up to 30 mm, creating a usable travel window of 15-45 mm. This stopper sets the end position but does not lock or hold the load without live air pressure.
