About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X60-20
The AirTAC SAIJ200X60-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty operations. The integrated rear stopper allows you to fine-tune the end position during commissioning without adding external stops.
This specific SKU provides a usable travel window of 40-60mm, letting you dial back the 60mm nominal stroke by up to 20mm. It features a carbon steel rod and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and because no magnet is specified here, position sensing would require adding the -S option for CMSE or DMSE switches.

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 SAIJ200X60-20 Is Used
Heavy Press Changeover
Dial in the 40-60mm travel window during product family switchovers to accommodate varying material thicknesses without repositioning the entire press fixture.
Adjustable End Stops
Use the rear screw mechanism to set precise retract positions on the fly for heavy forming operations, avoiding the need to swap out cylinders for different job lengths.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X60-20 the Right Cylinder?
The adjustable stroke is ideal for product-size changeovers on a line, allowing operators to set variable end-stops on the fly. For load-holding without live air pressure, remember this rear adjuster acts only as a travel stop and not a lock; you would need an external rod lock or a SAIL/BSAI cylinder for secure clamping.
To replace an ISO 15552 cylinder, match the 200mm bore, 60mm stroke, 20mm adjustment, G3/4 PT ports, and your required mounting style. SAIJ supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Despite the short 60mm stroke, the heavy tooling typically attached to a 200mm bore necessitates careful external guiding to manage side 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 SAIJ200X60-20 FAQ
The SAIJ200X200-20 uses a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the 60mm nominal stroke by up to 20mm. This creates a usable travel window of 40-60mm for fine-tuning the retract end position without changing the cylinder.
