About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X650-40S
The AirTAC SAIJ200X650-40-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty tasks requiring exact end-position tuning. A rear mechanical stopper allows you to trim the nominal 650 mm stroke back by up to 40 mm, creating a 610-650 mm usable travel window for precise product changeovers without adding external stops. It features a carbon steel rod and a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors.
The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered G3/4 ports ensure high flow capacity. The rear adjuster acts solely as a travel stop to set deceleration and end limits; it 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 SAIJ200X650-40S Is Used
Large Press Tuning
Dial in the exact 610-650 mm end-stop during heavy press commissioning to accommodate different workpiece thicknesses without swapping out the entire actuator.
Oversized Product Diverting
Adjust the retract position on the fly to handle varying pallet widths on a heavy-duty conveyor line, ensuring positive contact without reprogramming the motion controller.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X650-40S the Right Cylinder?
Select this 200 mm bore cylinder when an application demands maximum thrust (up to 3204 kgf at 1.0 MPa) alongside variable end-stop positioning. If you need less force, stepping down to a 160 mm bore drops the 0.5 MPa push thrust to 10053 N. The adjustable stroke is ideal for commissioning fine-tuning on large machines, whereas a fixed-stroke SAI cylinder is better suited for repetitive single-product cycles. For load-holding without live pressure, pair this cylinder with an external rod lock or choose an AirTAC SAIL or BSAI clamp-lock model.
Because the 650 mm stroke is substantial, the 40 mm diameter carbon steel rod and M36x2 thread require careful alignment to prevent side-loading damage; always use an external guide for heavy unsupported loads. This SAIJ200X650-40-S configuration uses PT ports, a carbon steel rod, and the -S magnet option. It supports the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It is dimensionally interchangeable per ISO 15552.

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 SAIJ200X650-40S FAQ
At its maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 650 mm nominal stroke by up to 40 mm, yielding a 610-650 mm travel window. It sets the end position and deceleration but does not function as a lock to hold the load without live air.
