About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X260-30
The AirTAC SAIJ200X260-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty operations. By integrating a 30mm adjustment screw, this model creates a usable travel window between 230mm and 260mm, allowing you to dial in the exact retract end-position without adding external stops.
Built with a robust 40mm carbon steel rod and an M36x2 thread, it handles substantial loads, though the 260mm stroke still requires an external guide to manage side loads. The extruded aluminum barrel features sensor grooves on both sides for flexible mounting of CMSE or DMSE switches, though a magnet is not included on this standard configuration. Seals are standard TPU, and the fluid must be air filtered to 40 um.

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 SAIJ200X260-30 Is Used
Heavy Press Tuning
Fine-tune the 230-260mm travel window during commissioning to apply exact clamping force on large metal components without swapping cylinders.
Product Size Changeover
Adjust the retract stop on the fly to accommodate varying pallet widths on a heavy-duty conveyor line, minimizing machine downtime.
Variable End-Stop Positioning
Use the 30mm adjustment screw to set precise retract positions for heavy lifting arms, ensuring perfect alignment before the transfer of heavy loads.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X260-30 the Right Cylinder?
Choose this 200mm bore cylinder when an application demands extreme force, pushing 15708N at 0.5 MPa. The 30mm adjustable travel is perfect for machine setups requiring variable end-stops or fine-tuning during commissioning, replacing the need for fixed-stroke SAI cylinders when product sizes vary.
Because the stroke is 260mm, an external guide is recommended to prevent excessive rod side-loading. Remember that the rear adjuster functions strictly as a travel stop, not a lock; the cylinder cannot hold a load without live air. For load-holding without pressure, consider an external rod lock, or explore AirTAC SAIL or BSAI models. This unit uses a PT tapered port and supports mountings Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ200X260-30 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 30mm, creating a usable travel window of 230mm to 260mm. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
