About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X260-50S
The AirTAC SAIJ200X260-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. An integrated magnet allows for position sensing using CMSE reed or DMSE electronic switches.
This 200mm bore actuator uses a robust 40mm carbon steel rod with an M36x2 thread, paired with G3/4 PT tapered ports for high airflow. The extruded aluminum barrel incorporates sensor grooves on both sides, and the variable air cushions at both ends work alongside the rear stopper to decelerate heavy loads smoothly.

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 SAIJ200X260-50S Is Used
Heavy Press Tuning
Fine-tune the 210-260mm travel window on heavy stamping or press equipment to accommodate different material thicknesses without swapping actuators.
Product Changeover
Rapidly adjust the rear stopper during production line format changes, dialing in the exact end position for new pallet or product sizes on the fly.
Large Assembly End-Stop
Set precise retraction limits for massive automated assembly stations, using the 50mm trim range to perfect machine alignment during initial setup.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X260-50S the Right Cylinder?
Choose this SAIJ200X260-50-S when your application requires extreme thrust and variable end-stops without adding external physical stops. Because the 260mm stroke exceeds 300mm? No, but at this massive 200mm bore, the heavy piston mass still warrants an external guide to prevent excessive rod side-loading. To match this ISO 15552 footprint, specify the 200mm bore, 260mm stroke, 50mm adjustment, G3/4 PT ports, and the -S magnet.
The rear adjuster acts strictly as a travel stop, not a locking device. It cannot hold a load without live air pressure; for true fail-safe load holding, consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock. Mounting options are limited to 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 SAIJ200X260-50S FAQ
At its maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the 260mm nominal stroke by up to 50mm, providing a usable travel window of 210-260mm. This stopper only sets the end position and does not lock the load without live air pressure.
