About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X90-50S
The AirTAC SAIJ200X90-50-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. Featuring a 200mm bore and a 90mm nominal stroke, its integrated rear adjuster allows you to trim the effective travel back by up to 50mm, creating a precise 40-90mm usable window. This eliminates the need to swap cylinders during commissioning or product changeovers.
Equipped with a -S magnet, this unit supports AirTAC CMSE reed and DMSE electronic sensors for accurate position feedback. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting. It features a robust 40mm carbon steel rod with an M36x2 thread, designed to withstand significant side loads. Sealed with standard TPU and utilizing PT tapered ports, this cylinder provides reliable, adjustable performance in demanding environments.

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 SAIJ200X90-50S Is Used
Heavy Press Tuning
Fine-tune the pressing depth of heavy machinery on the fly. The 40-90mm travel window allows operators to adjust end positions during product changeovers without replacing the cylinder.
Variable End Stops
Ideal for automated lines handling varying product sizes. The rear adjuster screw lets you set precise retraction limits for 15708N loads, ensuring accurate positioning without external stopper blocks.
Commissioning Calibration
Perfect for dialing in exact stroke distances during machine setup. The 50mm adjustment range provides flexibility to perfect the 90mm stroke during initial commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X90-50S the Right Cylinder?
If full 90mm travel is unnecessary, the 50mm adjustment screw allows you to dial in the exact end-stop without adding external mechanical stops. Because the stroke is 90mm, side-load stress is minimal, though the heavy 40mm rod naturally handles high bending forces.
Remember that the rear adjuster functions strictly as a travel stop, not a locking device; it cannot hold a load without continuous air pressure. For dead-load holding, explore the SAIL pneumatic lock or BSAI clamp-lock series. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552, featuring a PT port, carbon steel rod, and -S magnet for CMSE/DMSE 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 SAIJ200X90-50S FAQ
At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the 90mm nominal stroke by up to 50mm, creating a usable travel window of 40-90mm. It only sets the travel end and does not lock the load without live air pressure.
