About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X65-30
The AirTAC SAIJ200X65-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 35 to 65 mm. The extruded aluminum barrel includes sensor grooves on both sides for straightforward detection integration.
It uses a robust 40 mm carbon steel rod with an M36x2 thread, providing high rigidity against side loads. The rear stopper screw allows precise end-position tuning at commissioning without adding external stops. The adjuster acts solely as a travel stop, meaning the cylinder cannot hold a 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 SAIJ200X65-30 Is Used
Heavy Press Tuning
Dial in the exact 35 to 65 mm end position for heavy pressing and forming tasks during initial machine setup.
Product Changeover
Quickly adapt the stroke window on a production line when switching between different heavy assembly heights.
Variable End Stops
Use the rear adjuster to set precise retract stops for heavy material handling without external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X65-30 the Right Cylinder?
The 30 mm adjustment range is ideal for fine-tuning the end position during product changeovers rather than swapping a fixed-stroke SAI cylinder. Because the stroke is short, side-load risks are minimal, but the heavy mass still requires standard guiding.
For true load-holding without continuous air pressure, this adjustable stopper is insufficient; you must specify an SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock. This SKU is dimensionally interchangeable per ISO 15552 and is configured with PT tapered ports, standard carbon steel rod, no magnet, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ200X65-30 FAQ
The operating speed range for this 200 mm bore cylinder is 30-500 mm/s.
The rear adjuster screw lets you shorten the 65 mm nominal stroke by up to 30 mm, providing a usable travel window of 35 to 65 mm for fine-tuning the end position. The adjuster is a mechanical stop, not a lock, so it will not hold the load without live air pressure.
