About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X70-10S
The AirTAC SAIJ200X70-10-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations requiring precise end-position tuning. The integrated rear adjusting screw allows you to trim the 70mm nominal stroke back by up to 10mm, providing a highly specific 60-70mm usable travel window for exact product changeovers without swapping hardware.
This variant includes a standard magnet for position sensing via CMSE reed or DMSE electronic switches. It features a rugged 40mm carbon steel rod with an M36x2 thread, PT tapered ports, and variable air cushions at both ends. The extruded aluminum barrel offers sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

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 SAIJ200X70-10S Is Used
Heavy Press Fine-Tuning
Dial in the exact 60-70mm travel window on a high-force press to accommodate varying material thicknesses without changing the cylinder.
Machine Changeover
Quickly adjust the rear stopper during product line changeovers to set new end positions for heavy-duty assembly equipment.
Actuator Commissioning
Trim the stroke by up to 10mm during initial setup to perfectly align heavy tooling, avoiding the need for external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X70-10S the Right Cylinder?
Select this 200mm bore actuator when your application demands extreme thrust up to 15708N at 0.5 MPa alongside fine-tuned travel limits. The 10mm rear adjuster is ideal for dialing in the exact end-stop during machine commissioning, eliminating the need to bolt on external stoppers. If your setup requires load holding without live air pressure, note that the rear screw acts only as a travel stop and not a lock; you should instead explore the AirTAC SAIL or BSAI series.
For a direct ISO 15552 dimensional replacement, match the 200mm bore, 70mm stroke, 10mm adjustment range, PT port thread, and the -S magnet requirement. Because this model operates at the maximum thrust tier, ensure your mounting footprint accommodates the heavy loads.
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 SAIJ200X70-10S FAQ
It can deliver up to 318 kgf at its maximum 1.0 MPa pressure rating.
The rear adjusting screw acts as an external stopper that lets you shorten the 70mm nominal stroke by up to 10mm, creating a 60-70mm usable travel window. It is a travel stop only and does not hold the load without live air pressure.
