Airtac SAIJ200 Adjustable Cylinder SAIJ200X80-75
The AirTAC SAIJ200 Adjustable Cylinder SAIJ200X80-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 80mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X80-75
The AirTAC SAIJ200X80-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. By turning the stopper screw, you can trim the nominal 80 mm travel back by up to 75 mm, creating a wide 5-80 mm usable end-position window. This allows rapid fine-tuning at commissioning or during product changeovers without swapping the physical cylinder or adding external stops.
This 200 mm bore actuator uses a robust 40 mm carbon steel rod and a G3/4 PT port. It features variable air cushions at both ends to decelerate heavy moving loads across its 30-500 mm/s speed range. The rear adjuster acts purely as a mechanical travel stop and does not hold the load without live air pressure; for true fail-safe load holding, select an SAIL or BSAI series cylinder instead.

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 SAIJ200X80-75 Is Used
Heavy Press Fine-Tuning
Dial in the exact 5 to 80 mm pressing depth for high-force assembly operations without changing out physical cylinder hardware.
Product Size Changeovers
Adapt a heavy-duty packaging line to different pallet heights quickly by adjusting the rear stopper instead of repositioning the entire actuator.
Variable End-Stop Positioning
Set precise retraction limits on large automated platens, using the 75 mm adjustment window to accommodate multiple fixture thicknesses.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X80-75 the Right Cylinder?
The defining feature here is the 75 mm adjustment range, which is ideal for machinery that processes varying product sizes and needs a variable end-stop rather than a fixed 80 mm SAI cylinder.
When matching this for an ISO 15552 replacement, verify the 200 mm bore, 80 mm stroke, G3/4 PT ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2; note that FB, CA, CB, and CR are omitted). Because no magnet is specified, this unit cannot host CMSE or DMSE sensors. Furthermore, while the 40 mm rod handles high side loads, any stroke of 300 mm or longer on this series requires an external guide to prevent rod binding.
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 SAIJ200X80-75 FAQ
At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjusting screw acts as a mechanical stopper that can trim the effective travel by up to 75 mm. This creates a usable stroke window of 5 to 80 mm, allowing you to set the exact end position at commissioning without replacing the cylinder.
