About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X65-50S
The AirTAC SAIJ200X65-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. The -50 code means you can dial back the 65mm nominal stroke by up to 50mm, creating a highly flexible 15-65mm usable travel window for precise positioning.
This extruded aluminum barrel includes sensor grooves on both sides for CMSE and DMSE switches, with the -S magnet fitted for electronic or reed detection. The rear screw acts purely as a travel stop to fine-tune the end position without swapping the cylinder, but it does not hold the load without live air pressure. For load-holding requirements, an external pilot-operated check valve or the SAIL series is required.

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 SAIJ200X65-50S Is Used
Heavy Press Tuning
Dial in the exact 15-65mm crushing or forming depth on heavy industrial presses without changing the cylinder or adding external mechanical stops.
Product Changeover
Quickly adjust the end-stop position on automated lines when switching between product sizes, using the rear screw to set the new travel limit.
Assembly Calibration
Fine-tune the final end-of-stroke position during machine commissioning to ensure heavy components are seated perfectly without over-travel.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X65-50S the Right Cylinder?
Select this 200mm bore when your application requires extreme force but variable end-stops, such as heavy press tooling that undergoes frequent product changeover. If you need less force, stepping down to a 160mm bore yields 10053N at 0.5 MPa, which may better suit lighter assemblies. The 40mm rod and M36x2 thread provide high rigidity, but because the stroke is short, side-load risks are minimal compared to longer travel units.
Choose the adjustable SAIJ over a fixed SAI when you need on-the-fly commissioning adjustments without adding external stops. This model uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. To match this ISO 15552 replacement exactly, specify the 200mm bore, 65mm stroke, 50mm adjustment, G3/4 PT ports, carbon steel rod, and the -S magnet.
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 SAIJ200X65-50S FAQ
The rear adjuster screw lets you shorten the 65mm nominal stroke by up to 50mm, providing a usable travel window of 15-65mm. This stopper only sets the end position and deceleration; it does not lock or hold the load without continuous air pressure.
