About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X75-20S
The AirTAC SAIJ200X75-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated rear stopper allows you to fine-tune the effective travel down from the 75 mm nominal stroke, providing a precise 55-75 mm usable window without requiring external stops.
This heavy-duty actuator uses a carbon steel rod with an M36x2 thread and a PT tapered port. Unlike fixed-stroke SAI models, this adjustable version excels in setups requiring exact end-position tuning during commissioning. The rear screw acts purely as a travel stop for deceleration alongside the standard air cushions; it does not lock the load, so maintain live air or use a SAIL lock cylinder for holding.

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 SAIJ200X75-20S Is Used
Heavy Press Tuning
Dial in the exact 55-75 mm contact depth for high-tonnage pressing operations, ensuring perfect material deformation without over-traveling the 200 mm bore.
Product Size Changeover
Quickly adapt end-stops on a packaging line when switching to a new product size, using the rear adjuster to shift the 75 mm nominal travel window precisely.
Machine Commissioning
Fine-tune the retract end-position during initial machine setup, eliminating the need to physically swap out cylinders or bolt on bulky external stopper blocks.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X75-20S the Right Cylinder?
Choose the SAIJ adjustable design over a fixed SAI when you need to dial in the exact end-of-stroke position during product changeovers. Because the nominal stroke is 75 mm, the 20 mm adjustment range creates a highly versatile 55-75 mm travel window.
To replace an ISO 15552 cylinder, match the 200 mm bore, 75 mm stroke, 20 mm adjustment, PT port thread, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Although the stroke is short, the M36x2 rod handles high axial loads; for any lateral forces, always use an external guide. The operating speed for this bore size is 30-500 mm/s.

- ✓ 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 SAIJ200X75-20S FAQ
At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster screw lets you shorten the 75 mm nominal stroke by up to 20 mm, creating a usable travel window of 55-75 mm. This stopper only sets the travel end and does not lock the load without live air pressure.
