About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X260-30S
The AirTAC SAIJ200X260-30-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. It features a built-in rear stopper mechanism that allows you to trim the nominal 260 mm stroke back by up to 30 mm, creating a precise 230-260 mm usable travel window for on-the-fly commissioning adjustments.
This variant includes a standard carbon steel rod and a -S magnet for position sensing. The dual-side sensor grooves on the extruded aluminum barrel support AirTAC CMSE reed and DMSE solid-state switches. The rear adjuster acts strictly as a travel stop to decelerate the end-of-stroke position and does not function as a lock; for load-holding without live air pressure, consider the SAIL or BSAI series.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ200X260-30S Is Used
Heavy Press Changeover
Dial in the 230-260 mm travel window during product size changeovers on large forming presses without replacing the cylinder.
Variable End-Stop Setup
Fine-tune the retracted end position during machine commissioning to perfect material seating or clamping depth.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X260-30S the Right Cylinder?
The adjustable rear screw is ideal for product changeovers, allowing you to dial in the exact 230-260 mm travel distance without swapping out the entire cylinder or adding bulky external stops.
When ordering for an ISO 15552 replacement, verify the 260 mm stroke, 30 mm adjustment range, PT (tapered) G3/4 port thread, and the -S magnet option. Because the stroke is 260 mm, which is 300 mm or more, note that long unsupported strokes require an external guide to prevent excessive side-loading on the rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
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 SAIJ200X260-30S FAQ
At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster screw allows you to shorten the nominal 260 mm stroke by up to 30 mm, providing a usable travel window of 230 to 260 mm. It acts as a physical stop to set the end position and is not a lock.
