About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X300-100
Its 100mm adjustment mechanism allows you to dial back the 300mm nominal stroke, creating a precise 200-300mm usable travel window for product changeovers without swapping out the entire actuator. The extruded aluminum barrel features sensor grooves on both sides for straightforward position feedback integration.
This heavy-duty pneumatic actuator utilizes a robust 40mm carbon steel rod and a PT G3/4 port to efficiently handle high flow requirements. While the integrated air cushions at both ends manage deceleration, the rear adjuster acts purely as a travel stop and cannot hold the load without live air pressure. For load-holding requirements on vertical lifts, consider pairing this setup with an external pilot-operated check valve or exploring the AirTAC 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 SAIJ200X300-100 Is Used
Heavy Pressing Calibration
Dial in the exact 200-300mm travel window during machine setup to accommodate varying material thicknesses in large stamping or pressing lines without changing the physical cylinder mounting.
Pallet Positioning Stops
Adjust the rear stopper on the fly to handle different pallet sizes on a heavy-duty transfer conveyor, ensuring precise end-position halts for automated loading processes.
Large Assembly Forming
Fine-tune the end-stroke during product changeovers in large-scale automotive or industrial assembly lines, relying on the 40mm carbon steel rod to withstand significant operational stress.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X300-100 the Right Cylinder?
The 100mm adjustable end-stop is ideal for machinery requiring variable end positions during commissioning or format changes, offering flexibility that a fixed-stroke SAI cylinder cannot provide. When replacing an ISO 15552 cylinder, verify the 200mm bore, 300mm stroke, 100mm adjustment range, PT G3/4 port, and standard carbon steel rod. Because the nominal stroke is 300mm, it is critical to use an external guide to support the heavy 40mm rod and prevent excessive side-loading during extended travel.
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 SAIJ200X300-100 FAQ
If you increase the pressure to 0.7 MPa, the push force rises to 21991N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 300mm down to a minimum of 200mm. This creates a 200-300mm adjustable window, enabling precise end-position tuning at commissioning without needing external stops.
