Airtac SAIJ200 Adjustable Cylinder SAIJ200AX195-75
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200AX195-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 195mm 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 SAIJ200AX195-75
The AirTAC SAIJ200X195-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a substantial 28274N of push force at 0.9 MPa. The integrated rear stopper allows you to trim the effective travel down from the 195mm nominal stroke, yielding a usable window of 120-195mm to perfectly dial in end positions during machine commissioning.
This large-bore unit incorporates a SUS420J2 stainless steel rod (material code A) for enhanced resistance to corrosion and wear. It uses PT tapered port threads (G3/4) and omits the -S magnet, meaning electronic DMSE or reed CMSE sensors cannot be directly attached to this specific configuration. The extruded aluminum barrel design includes dual sensor grooves, though they remain unused here, and the variable air cushions at both ends help manage the heavy 3204 kgf maximum kinetic impacts.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX195-75 Is Used
Heavy Press Tuning
Fine-tune the exact end-of-stroke clamping position on high-force presses during initial setup, absorbing kinetic energy using the 40mm cushion while trimming travel back up to 75mm.
Product Changeovers
Adapt a heavy-duty conveyor diverter on the fly for different package sizes by dialing back the 195mm stroke to 120mm without changing the cylinder mounting hardware.
Large Assembly Jigs
Provide adjustable end-stops for massive automotive sub-assembly jigs where the 200mm bore delivers the necessary 2182N pull force at 0.7 MPa to seat heavy components.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX195-75 the Right Cylinder?
Selecting this 200mm bore cylinder makes sense when your application requires up to 15708N of thrust at a standard 0.5 MPa, stepping up significantly from the 100mm bore which provides 3927N at the same pressure. The 75mm adjustment range is highly beneficial for product changeovers, allowing operators to vary the end-stop by up to 75mm without physically swapping the cylinder or adding external mechanical stops. Because the stroke is 195mm, which is close to the bore diameter, side-load stress is manageable, but an external guide is still recommended for heavy loads.
When seeking an ISO 15552 dimensionally interchangeable replacement, match the 200mm bore, 195mm stroke, PT G3/4 port, and the 75mm adjustment code. Remember that the rear adjuster and air cushions function only as travel stops and deceleration devices; they do not hold the load. If your setup requires true load-holding without live air pressure, you must employ an external pilot-operated check valve or switch to an AirTAC SAIL or BSAI series cylinder.
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 SAIJ200AX195-75 FAQ
At an operating pressure of 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum rated pressure of 1.0 MPa, it delivers up to 3204 kgf of thrust.
The rear of the cylinder features an external stopper screw that allows you to shorten the effective stroke from its 195mm nominal length down to as little as 120mm. This provides a 75mm tuning window to set exact end positions without swapping out the cylinder.
