About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-100S
The AirTAC SAIJ200X165-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty operations. It yields 15708N of push force and 15080N of pull force at 0.5 MPa. The integrated -100 adjustment code creates a usable travel window between 65 and 165 mm, enabling precise end-position calibration without swapping out the entire actuator.
This model features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. Fluid is filtered air operating between 0.15 and 1.0 MPa. The extruded aluminum barrel includes sensor grooves on both sides, and the unit operates at a 30-500 mm/s speed range with PT tapered ports sized at G3/4.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-100S Is Used
Heavy Press Tuning
Dial in the exact 65-165 mm end-position during heavy press commissioning to prevent over-travel without adding external mechanical stops.
Product Size Changeover
Quickly adjust the stroke down by up to 100 mm on a packaging line to accommodate different large-format product sizes on the fly.
Heavy Duty Positioning
Leverage the 15708N push force to move massive pallets or metal components, using the adjustable stop to fine-tune the resting position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-100S the Right Cylinder?
Selecting this 200 mm bore actuator is ideal when an application demands extreme force alongside variable end-stops, such as 15708N push at 0.5 MPa. If you need less force, stepping down to a 160 mm bore yields 10053N push, but this SAIJ200X165-100-S is built for the heaviest loads. The 100 mm adjustment window is perfect for product-size changeovers on a line, allowing you to dial back the 165 mm nominal stroke anywhere down to 65 mm. For exact ISO 15552 replacement matching, confirm the 200 mm bore, 165 mm stroke, 100 mm adjust, PT G3/4 port, and the -S magnet.
Because the nominal stroke is 165 mm, an external guide is recommended to manage side loads on the 40 mm rod. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for true load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder. Mounting options include 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 SAIJ200AX165-100S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum 1.0 MPa pressure, it achieves up to 3204 kgf.
The rear adjusting screw allows you to shorten the effective stroke by up to 100 mm. This creates a usable travel window of 65 to 165 mm from the nominal 165 mm stroke, enabling fine-tuning of the end position without replacing the cylinder.
