About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-100
The AirTAC SAIJ200X800-100 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty positioning. A rear adjusting screw allows you to trim the nominal 800 mm stroke back by up to 100 mm, creating a precise 700-800 mm usable travel window without adding external stops.
This model features an extruded aluminum barrel with sensor grooves on both sides, operating at speeds of 30-500 mm/s. It is important to note that the rear adjuster functions strictly as a travel stop for end-position tuning, not as a load-holding lock; true position holding without live air requires a SAIL or BSAI variant. 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 SAIJ200X800-100 Is Used
Heavy Press Tuning
Dial in the exact 700-800 mm end-stop during heavy press commissioning to accommodate varying material thicknesses without machining new hard stops.
Large Assembly Changeover
Quickly adjust the rear stopper for product size changeovers on large assembly lines, saving setup time versus physically replacing a fixed-stroke cylinder.
Heavy Conveyor Positioning
Fine-tune the end position of heavy-load conveyor transfers, using the 40 mm carbon steel rod to handle high dynamic forces safely.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-100 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires the maximum standard thrust class (up to 3204 kgf at 1.0 MPa). The 100 mm adjustment range is ideal for product changeovers, allowing you to dial in the exact end-of-stroke position during commissioning rather than swapping out a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 800 mm stroke, 100 mm adjustment range, PT tapered G3/4 port, and standard carbon steel rod. Because this unit features an 800 mm stroke, the long unsupported rod travel demands an external guide to prevent side-loading damage, even with the robust 40 mm rod diameter. No magnet is specified, so position sensing via CMSE or DMSE switches is not supported without adding the -S option.

- ✓ 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 SAIJ200X800-100 FAQ
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 800 mm down to 700 mm. This creates a 700-800 mm usable window for fine-tuning the end position at commissioning, but it does not lock the load without continuous air pressure.
