About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X65-20S
The AirTAC SAIJ200X65-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window from 45 to 65 mm without adding external stops. Built with a robust 40 mm carbon steel rod and a PT tapered port thread, it delivers massive thrust up to 15708 N at 0.5 MPa, making it ideal for heavy-duty pressing and clamping. The extruded aluminum barrel includes sensor grooves on both sides, and because this is an -S variant, it comes magnet-equipped for seamless position detection.
Unlike a fixed-stroke SAI cylinder, this model lets you dial in the retract end-position precisely during commissioning or product changeover. The rear adjuster acts purely as a mechanical stop to set the travel limit, working alongside the adjustable air cushions at both ends to decelerate the massive 200 mm piston. It is important to note that neither the adjuster nor the cushion holds the load without live air pressure; for true load-holding, you would need an external rod lock or a related series like SAIL or BSAI.

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 SAIJ200X65-20S Is Used
Heavy Press Tuning
Dial in the exact 45 to 65 mm pressing depth during setup to accommodate different material thicknesses without swapping out the entire cylinder.
Variable End-Stop Clamping
Adjust the retract position on the fly for product changeovers, using the rear screw to set precise clamping limits for oversized assemblies.
Machine Changeover Setup
Fine-tune the travel end-point during commissioning of new production runs, using the 20 mm adjustment window to perfect the motion sequence.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X65-20S the Right Cylinder?
Choose this 200 mm bore if your application requires extreme force, pushing 15708 N at 0.5 MPa (or 21991 N at 0.7 MPa). The adjustable stroke is highly beneficial when you need variable end-stops for different product sizes on the same line, giving you a 20 mm trim window on a 65 mm base stroke.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 65 mm stroke, 20 mm adjustment range, PT port thread, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR footprints. Although the 65 mm stroke is relatively short, the heavy 40 mm rod and high thrust forces mean you should ensure your mounting interface and external guidance can handle the side loads generated during high-energy cycles. The -S magnet works precisely with AirTAC CMSE reed and DMSE electronic sensors.

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 SAIJ200X65-20S FAQ
If you increase the pressure to 0.7 MPa, the push force rises to 21991 N.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the nominal 65 mm stroke by up to 20 mm, providing an effective travel window of 45 to 65 mm. It only sets the end position and does not lock or hold the load without continuous air pressure.
