About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX600-75
The AirTAC SAIJ200X600-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits fine-tuning of the end position. It provides a usable travel window of 525-600 mm from the 600 mm nominal stroke, allowing precise positioning without swapping the unit. Delivering 15708 N of push force at 0.5 MPa, it handles heavy loads with a robust 40 mm SUS420J2 stainless steel rod.
This pneumatic actuator features PT tapered port threads and operates at speeds of 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, though this specific configuration omits the magnet for switches. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX600-75 Is Used
Heavy Press Tuning
Dial in the exact 525-600 mm end position during machine commissioning to ensure perfect pressing force without machining external stoppers.
Product Changeover
Quickly adapt the travel window on a packaging line when switching to different box sizes, using the rear screw to set the new retract stop.
Large Assembly Jigs
Position heavy automotive components accurately during assembly, relying on the 15708 N thrust and the fine 75 mm stroke adjustment.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX600-75 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires 15708 N of thrust at 0.5 MPa and demands in-field stroke trimming. If you need less force, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa. The 75 mm adjustment range is ideal for accommodating product size changeovers on a line, whereas a fixed SAI cylinder cannot adapt without external stops. For load-holding without live pressure, select a SAIL or BSAI cylinder instead.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 600 mm stroke, 75 mm adjustment, PT ports, and SUS420J2 rod material. Because the 600 mm stroke is substantial, the 40 mm rod still requires an external guide to prevent excessive side-loading on the bearing.
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 SAIJ200AX600-75 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can deliver up to 3204 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that trims the retract stroke. For this model, it shortens the 600 mm nominal stroke to any effective length down to 525 mm. It does not lock the load without live air.
