About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X85-75
The AirTAC SAIJ200X85-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708N at 0.5 MPa. With a nominal 85mm stroke and a 75mm adjustment range, it provides a highly flexible 10-85mm usable travel window. This allows operators to dial in the exact end position during commissioning without swapping out the physical cylinder.
It features a robust 40mm carbon steel rod and a G3/4 PT tapered port to handle high flow and heavy loads. The extruded aluminum barrel includes sensor grooves on both sides for CMSE or DMSE switches, though this specific SKU is configured without a magnet. The rear stopper acts purely as a travel limit and does not hold the load without live air pressure.

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 SAIJ200X85-75 Is Used
Heavy Press Tuning
Fine-tune the end position of high-force pressing operations within the 10-85mm window without changing the cylinder.
Product Size Changeover
Quickly adjust the stroke stop on packaging lines to accommodate different product sizes on the fly.
Machine Setup
Dial in the exact retract position during initial commissioning to avoid adding external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X85-75 the Right Cylinder?
If the full 85mm stroke is always required, a fixed SAI cylinder is simpler, but the SAIJ variant shines when you need on-the-fly repositioning. Remember that the rear adjuster is a stop, not a lock; for load-holding without live air, consider an external rod lock or the SAIL series.
Because the usable travel window is 10-85mm, ensure your setup accommodates this specific adjustment band. This model uses the standard SAIJ mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts. The 40mm rod thread handles significant side loads, but an external guide is still recommended for any off-center 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 SAIJ200X85-75 FAQ
At 0.7 MPa, the push force increases to 21991N.
The rear adjuster screw allows you to trim the effective travel back by up to 75mm from the nominal 85mm stroke, creating a 10-85mm usable travel window. The adjuster acts as a mechanical stop and does not lock the load without continuous air pressure.
