About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-10
The AirTAC SAIJ200X90-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 80-90 mm, allowing you to dial in the exact retract position without adding external stops. In the 200 mm bore class, it delivers massive thrust up to 15708 N at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the internal magnet. The rear adjuster acts purely as a mechanical stop to fine-tune the end position and must not be confused with a locking device.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-10 Is Used
Heavy-Duty Pressing
Utilizes the 15708 N thrust at 0.5 MPa to securely seat large bearings or stamp heavy plates, with the 10 mm adjuster allowing precise bottoming-out depth calibration.
Machine Changeover
Quickly adapts the retract end-stop within the 80-90 mm window during production line format changes, eliminating the need to physically swap cylinders or reposition hard stops.
High-Force End Positioning
Moves substantial masses to a defined retract location using the robust 40 mm rod, relying on the built-in air cushions and the external stopper for smooth final positioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-10 the Right Cylinder?
Choose this 200 mm bore cylinder when your application demands maximum push force, stepping up significantly from the 160 mm bore which provides 10053 N at 0.5 MPa. The adjustable stroke is highly beneficial during machine commissioning or product changeovers, letting you shift the end-stop by up to 10 mm without swapping out the entire cylinder body. Because the stroke is 90 mm, side-load risks are minimal, but always ensure the load is guided to prevent rod binding.
When replacing an ISO 15552 cylinder, verify the 200 mm bore, 90 mm stroke, 10 mm adjustment range, PT G3/4 port, and the absence of a magnet. If your setup requires the cylinder to hold its position safely without continuous live air pressure, note that the rear adjuster here only halts travel—it does not lock the load. For true fail-safe load holding, consider the AirTAC SAIL or BSAI series instead. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ200AX90-10 FAQ
At a 0.5 MPa operating pressure, the SAIJ200X90-10 generates a push force of 15708 N and a pull force of 15080 N. It can reach a maximum push force of 28274 N at 1.0 MPa.
The SAIJ200X90-10 has a nominal stroke of 90 mm with a 10 mm adjustment range, creating a usable travel window of 80 to 90 mm. A rear screw acts as a mechanical stopper to fine-tune the retract position, but it does not lock the load without live air pressure.
