Airtac SAIJ200 Adjustable Cylinder SAIJ200BX650-100
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200BX650-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 650mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX650-100
The AirTAC SAIJ200X650-100 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, featuring a 650 mm nominal stroke that can be dialed back by up to 100 mm via a rear adjusting screw. This yields a precise 550-650 mm usable travel window, allowing you to fine-tune the retract end position during commissioning without swapping out the actuator. Operating at 0.15-1.0 MPa, it delivers a robust 15708 N of push force and 15080 N of pull force at 0.5 MPa.
This configuration features a SUS304 stainless steel rod for superior corrosion resistance and ships without a magnet. The extruded aluminum barrel includes sensor grooves on both sides. Because the stroke reaches 650 mm, the 40 mm diameter rod and M36x2 thread will still experience leverage forces, meaning an external guide rail is strongly recommended to prevent excessive side-loading on the seals.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX650-100 Is Used
Heavy Press Positioning
Dial in the exact 550-650 mm retract distance during heavy press setup, accommodating different die heights without installing external mechanical stops.
Large Product Changeover
Adapt a heavy-duty conveyor diverter on the fly by trimming the stroke up to 100 mm to handle varying pallet sizes during production line transitions.
Machine Commissioning
Fine-tune the end-of-travel position during initial machine commissioning to perfectly sync the 15708 N thrust stroke with downstream equipment.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX650-100 the Right Cylinder?
Selecting this 200 mm bore actuator makes sense when your machinery requires extreme thrust—such as 15708 N at 0.5 MPa—that smaller bores cannot provide. If your application does not demand this capacity, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, which may offer a more compact footprint. The defining advantage of the SAIJ series over a fixed-stroke SAI cylinder is the ability to adjust the end-stop on the fly; the rear screw acts purely as a travel stop for deceleration and positioning, not as a lock. To hold a load securely without live air pressure, you must integrate an external pilot-operated check valve or select an AirTAC SAIL or BSAI cylinder.
For a true ISO 15552 dimensional replacement, verify the 200 mm bore, 650 mm stroke, PT tapered port threads, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this adjustable variant.
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 SAIJ200BX650-100 FAQ
At a standard 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the effective stroke from its 650 mm nominal length down to 550 mm, creating a 550-650 mm travel window. This stopper only sets the end position and deceleration; it does not lock the load without continuous air pressure.
