About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-10
The AirTAC SAIJ200X500-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708N at 0.5 MPa. Its 10mm adjustment screw allows you to fine-tune the effective travel to a precise 490-500mm window. This feature eliminates the need to swap cylinders or bolt on external stops during machine commissioning or product changeovers.
Built for demanding environments, this unit features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and robust side-load handling. The extruded aluminum barrel includes sensor grooves on both sides, and fluid is supplied via PT tapered ports. The rear adjuster acts strictly as a travel stop for end-position tuning, not a lock, meaning live air is required to hold the load.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-10 Is Used
Heavy Fixture Positioning
Fine-tune the 490-500mm end stop on large welding or machining fixtures to accommodate slight part tolerances without redesigning the actuator setup.
Press and Forming End-Stops
Dial in the exact bottoming position of a high-force press, using the 15708N thrust capacity, while relying on the rear screw to set the precise travel limit.
Large Assembly Changeover
Quickly adjust the stroke by up to 10mm during product line changeovers, saving time compared to physically replacing a fixed-stroke SAI cylinder.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-10 the Right Cylinder?
Select this 200mm bore cylinder when an 80mm bore provides insufficient force (80mm yields 2513N push at 0.5 MPa) and you need heavy-duty actuation. The adjustable 490-500mm travel window is ideal for dialing in exact end positions on large fixtures without changing the cylinder. To replace an ISO 15552 cylinder, match the 200mm bore, 500mm stroke, 10mm adjustment, PT port thread, and mounting style.
Because the 500mm stroke is substantial, an external guide is recommended to prevent excessive side-loading on the rod despite the robust 40mm diameter. If your application requires holding the load without continuous air pressure, pair this cylinder with an external rod lock or choose the AirTAC SAIL or BSAI series instead. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ200AX500-10 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach a maximum push force of 3204 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 500mm nominal stroke by up to 10mm, creating a 490-500mm usable travel window. It only sets the end position and does not lock the load without live air pressure.
