About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X850-100
The AirTAC SAIJ200X850-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits fine-tuning of the end position during commissioning. The integrated adjustment screw allows you to trim the nominal 850mm stroke back by up to 100mm, creating a precise 750-850mm usable travel window without bolting on external stops.
This 200mm bore unit uses a robust G3/4 PT port and a 40mm carbon steel rod with an M36x2 thread to handle high side loads. It includes variable air cushions at both ends—offering 50mm of cushioning—to decelerate the massive moving mass. The extruded aluminum barrel features sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches, though no magnet is specified for this configuration.

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 SAIJ200X850-100 Is Used
Heavy Press Tuning
Fine-tune the 850mm stroke down by 100mm to set exact pressing depths on large metal forming equipment without changing the cylinder.
Assembly Line Changeover
Adjust the 750-850mm travel window rapidly during product size transitions on automated assembly lines to accommodate different part heights.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X850-100 the Right Cylinder?
The 100mm adjustment range is ideal for heavy machinery requiring product-size changeovers, allowing operators to dial in the exact 750-850mm travel without swapping the cylinder. Because the 850mm stroke is substantial, an external guide should be used to prevent rod deflection and premature seal wear.
For a dimensionally interchangeable ISO 15552 replacement, match the 200mm bore, 850mm stroke, 100mm adjustment, G3/4 PT port, and carbon steel rod. The mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster and air cushions act only as travel stops and deceleration devices; they do not hold the load without live air. For position holding without pneumatic pressure, consider the SAIL or BSAI series.
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 SAIJ200X850-100 FAQ
The rear adjuster screw allows you to shorten the nominal 850mm stroke by up to 100mm, providing a usable travel window of 750-850mm. This stopper only sets the end position; it does not lock the load without continuous air pressure.
