About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-30
The AirTAC SAIJ200X500-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a substantial 15708N push force at 0.5 MPa and utilizes a 30mm adjustment range, creating a precise 470-500mm usable travel window for end-position tuning. The SUS420J2 stainless steel rod offers enhanced corrosion resistance compared to standard carbon steel.
This heavy-duty actuator uses a PT tapered G3/4 port and achieves a maximum speed of 30-500 mm/s. The external rear stopper allows you to dial back the stroke without swapping the cylinder, while the extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-30 Is Used
Heavy Press Tuning
Dial in the exact 470-500mm end-stop during heavy press commissioning to accommodate varying material thicknesses without changing the actuator.
Product Changeover
Quickly adjust the retract end-position by up to 30mm on automated assembly lines when switching to a new product size.
High-Force Positioning
Leverage the 15708N thrust at 0.5 MPa to move heavy pallets or molds into a precise final location before the process begins.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-30 the Right Cylinder?
Choose this 200mm bore when the 160mm class (delivering 10053N push at 0.5 MPa) is insufficient for your high-force application. The 30mm rear adjuster is ideal for fine-tuning the end position during machine setup or product changeover, avoiding the need to bolt on external stops or swap out a fixed-stroke SAI cylinder. Remember that the rear adjuster acts only 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.
At 500mm of stroke, the 40mm diameter rod and M36x2 thread provide a robust interface, but long unsupported strokes still require an external guide to prevent excessive side-loading. This SAIJ model is dimensionally interchangeable per ISO 15552 and supports a reduced mounting set including 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 SAIJ200AX500-30 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach up to 3204 kgf at its maximum 1.0 MPa pressure rating.
The rear adjuster acts as an external mechanical stop that allows you to shorten the nominal 500mm stroke by up to 30mm, providing a usable travel window of 470-500mm. It only sets the end position and does not lock the load without live air pressure.
