About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X375-40
The AirTAC SAIJ200X375-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, engineered for heavy-duty industrial applications. The integrated rear stopper provides a 40mm adjustment range, allowing you to fine-tune the effective travel window down to 335mm without swapping hardware.
This extruded aluminum barrel utilizes a robust 40mm carbon steel rod with M36x2 threading and PT tapered port threads for the G3/4 air supply. Operating at speeds of 30-500mm/s, it includes variable air cushions at both ends to decelerate massive loads smoothly. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for secure load-holding, consider the SAIL or BSAI series.

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 SAIJ200X375-40 Is Used
Heavy Press Tuning
Dial in the exact 335-375mm end-stop during heavy press commissioning to accommodate varying material thicknesses without external shims.
Automated Line Changeover
Rapidly adjust the stroke window on production lines handling different large-scale product sizes, minimizing downtime between runs.
Large Fixture Positioning
Set precise retract positions for massive robotic fixtures, relying on the 40mm stopper to fine-tune the final end-point safely.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X375-40 the Right Cylinder?
The 40mm adjustment window is ideal for product changeovers, allowing precise end-position tuning at commissioning without adding external stops. When replacing an ISO 15552 cylinder, match the 375mm stroke, 40mm adjustment, G3/4 PT ports, and standard carbon steel rod. Because the stroke is 375mm, an external guide is recommended to prevent excessive side-load wear on the 40mm rod. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and 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 SAIJ200X375-40 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 375mm nominal stroke by up to 40mm, creating a 335-375mm usable travel window. It only sets the end position and does not lock or hold the load without continuous air pressure.
