About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-40
The AirTAC SAIJ200X175-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to 135 mm from the 175 mm nominal stroke. Equipped with a robust 40 mm piston rod and a G3/4 port, it delivers massive thrust up to 15708 N at 0.5 MPa, making it ideal for heavy-duty industrial applications.
This unit features a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and while this specific SKU lacks a magnet, the design accommodates AirTAC CMSE reed and DMSE electronic sensors when needed.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-40 Is Used
Heavy Press Tuning
Dial in the exact 135-175 mm end position for heavy pressing and forming operations without adding external mechanical stops.
Product Changeover
Quickly adjust the stroke length on packaging lines to accommodate different product sizes during line changeovers.
Machine Commissioning
Fine-tune the retract end-position during initial setup to align heavy tooling precisely without replacing the entire cylinder.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX175-40 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires extreme force, as stepping down to a 160 mm bore reduces your push force to 10053 N at 0.5 MPa. The 40 mm adjustment range is perfect for variable end-stop positioning during machine setup or product changeover, eliminating the need to swap out a fixed-stroke SAI cylinder. For a direct ISO 15552 replacement, match the 175 mm stroke, 40 mm adjuster, PT G3/4 port, and your required mounting option from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Although the 40 mm rod handles high side loads, a stroke of 175 mm still benefits from an external guide to prevent premature wear. Remember that the rear adjuster functions strictly as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an external rod lock or the SAIL series.
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 SAIJ200AX175-40 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 reach up to 3204 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 175 mm nominal stroke by up to 40 mm, creating a usable travel window of 135-175 mm. It only sets the end position and does not lock the load.
