About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X650-75
The AirTAC SAIJ200X650-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a usable travel window of 575 to 650 mm. This makes it highly suitable for heavy-duty press and lift operations requiring precise end-position tuning.
The external adjustment screw acts strictly as a mechanical stop to dial in the retract position during commissioning or product changeover without swapping the cylinder. It is not a lock, so live air is required to hold the load. For drop-prevention, external rod locks or related AirTAC types like SAIL or BSAI are necessary. The unit operates at 30-500 mm/s and omits FB, CA, CB, and CR mounts, utilizing a reduced set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces.

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 SAIJ200X650-75 Is Used
Heavy Press Tuning
Dial in the exact 575-650 mm retract position during heavy press commissioning to accommodate varying material thicknesses without adding external physical stops.
Product Size Changeover
Quickly adjust the end-stop on a multi-product line. The 75 mm rear screw window lets operators switch between different large pallet sizes seamlessly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X650-75 the Right Cylinder?
The 75 mm adjustment range is chosen when a machine handles multiple product sizes, allowing you to fine-tune the retract end-stop on the fly instead of installing fixed spacers or ordering a new cylinder.
Because the 650 mm stroke is long, the M36x2 rod and carbon steel construction will not prevent excessive side-loading on their own; an external guide rail is mandatory to prevent premature seal wear. This configuration uses PT tapered ports (G3/4), no magnet, and is dimensionally interchangeable per ISO 15552 mounting-interface dimensions.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ200X650-75 FAQ
At its maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf of push force.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 650 mm down to 575 mm. This provides a 75 mm tuning window for product changeovers without replacing the cylinder, though it does not lock or hold the load without continuous air pressure.
