About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X550-10S
The AirTAC SAIJ200X550-10-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 200mm bore and a 550mm stroke, yielding a usable travel window of 540 to 550mm. This built-in adjustability allows you to fine-tune the retract end position during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and because this is an -S variant, it contains a magnet for use with AirTAC CMSE reed and DMSE electronic sensors.
In the 200mm bore class, this cylinder generates substantial thrust, pushing with 15708N and pulling with 15080N at 0.5MPa. It uses a G3/4 PT tapered port and a robust 40mm carbon steel rod with an M36x2 thread. The variable air cushioning at both ends decelerates the heavy load, but remember the rear adjuster is a travel stop, not a lock; it cannot 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 SAIJ200X550-10S Is Used
Heavy Press Tuning
Dial in the exact 540-550mm retract position on a heavy press during commissioning, ensuring perfect contact without physically swapping the cylinder.
Product Changeover
Quickly adjust the end-stop by up to 10mm on an assembly line when transitioning between product sizes, minimizing machine downtime.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X550-10S the Right Cylinder?
The 10mm adjustment range on this model is ideal for dialing in exact retract positions during machine setup or product changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder.
Because the 550mm stroke is substantial, the 40mm rod and M36x2 thread provide necessary rigidity, but an external guide is still recommended to prevent excessive side-loading on the piston. For holding loads without continuous air pressure, this standard SAIJ adjuster will not suffice; you should explore an external rod lock, a pilot-operated check valve, or related AirTAC types like the SAIL or BSAI. This model is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

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 SAIJ200X550-10S FAQ
At the maximum pressure of 1.0MPa, the push force reaches 3204 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke by up to 10mm, creating a usable travel window of 540-550mm. It is designed for fine-tuning the end position and is not a lock, meaning it cannot hold a load without live air pressure.
