About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-50S
The AirTAC SAIJ200X500-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 21991N and pulling 15080N at 0.7 MPa, making it suitable for heavy-duty automation. The -50 adjustment code creates a usable travel window of 450-500mm, allowing you to dial back the nominal 500mm stroke precisely during machine commissioning without adding external stops.
This model includes a standard carbon steel rod and a -S magnet for position sensing. The extruded aluminum barrel features sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic switches. It uses a G3/4 PT port and supports a speed range of 30-500mm/s. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR styles.

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 SAIJ200X500-50S Is Used
Heavy Press Tuning
Fine-tune the 450-500mm travel window during setup to precisely control heavy-duty pressing operations without mechanical shims.
Product Changeover Stops
Quickly adjust the retract end-position on packaging lines when switching to different package lengths.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-50S the Right Cylinder?
Choose this 200mm bore when maximum output is required; stepping down to a 160mm bore reduces your 0.7 MPa push force to 14074N. The adjustable stroke is selected over a fixed SAI cylinder when you need variable end-stops for product changeovers. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider an external rod lock or the SAIL series. As a dimensionally interchangeable ISO 15552 cylinder, match your replacement by bore, 500mm stroke, 50mm adjustment, G3/4 port, and -S magnet. Given the 500mm stroke, an external guide is recommended to prevent side-load damage to the 40mm rod.
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 SAIJ200X500-50S FAQ
At its maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster screw lets you shorten the effective travel from the nominal 500mm down to 450mm. It acts as a mechanical stop to fine-tune end positions, but it is not a lock and will not hold the load without continuous air pressure.
