About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX80-20
The AirTAC SAIJ200X80-20 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster. It provides a nominal 80 mm stroke that can be fine-tuned down by 20 mm, giving you a precise 60-80 mm usable travel window for exact end-position calibration. Belonging to the 200 mm bore class, it delivers immense thrust up to 15708 N at 0.5 MPa, making it suitable for heavy-duty pressing and clamping operations.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to easily mount CMSE reed or DMSE electronic sensors if position feedback is needed. The rear stopper acts purely as a travel limit and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX80-20 Is Used
Heavy-Duty Press Tuning
Dial in the exact 60-80 mm travel window during machine commissioning to achieve precise pressing depths on heavy industrial assemblies without external stoppers.
Product Changeover
Quickly adjust the end position to accommodate varying product sizes on a high-force line, using the 20 mm rear screw to fine-tune the stroke on the fly.
Industrial Clamping
Leverage the 15708 N push force at 0.5 MPa to secure massive workpieces, relying on the rear stopper to consistently set the clamp position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX80-20 the Right Cylinder?
Choose this 200 mm bore when your application requires extreme force, stepping up from the 160 mm bore which provides 10053 N of push force at 0.5 MPa. An adjustable stroke is highly beneficial here for machine setup and product changeover, allowing you to dial in the exact 60-80 mm end-stop without swapping cylinders or adding external stops. Since the stroke is short, side-loading is minimal, but always ensure the load is guided to prevent binding.
For an exact ISO 15552 replacement match, verify a 200 mm bore, 80 mm stroke, 20 mm adjustment range, PT port threads, and the SUS420J2 rod material. Remember that the rear adjuster only sets the travel end; if you need to hold the load securely without continuous air pressure, you must integrate an external rod lock or select an AirTAC SAIL or BSAI series cylinder.

- ✓ 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 SAIJ200AX80-20 FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder delivers a push force of 15708 N and a pull force of 15080 N. It can reach a maximum push force of 28274 N at 0.9 MPa.
The rear adjuster screw allows you to mechanically shorten the 80 mm nominal stroke by up to 20 mm. This creates a 60-80 mm adjustable travel window, letting you fine-tune the end position at commissioning without replacing the cylinder.
