About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX50-50S
The AirTAC SAIJ200X50-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 0-50 mm. It delivers immense thrust, generating 15708 N of push force and 15080 N of pull force at 0.5 MPa. The bore utilizes a robust 40 mm piston rod and a PT tapered G3/4 port to handle high flow requirements.
This variant features a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX50-50S Is Used
Heavy Press Fine-Tuning
Dial in the exact 0-50 mm end position during heavy press setup to accommodate material thickness variations without external stops.
Product Changeover
Quickly adjust the travel window on automated lines when switching product sizes, leveraging the 15708 N force for robust actuation.
High-Force Positioning
Utilize the massive thrust and SUS420J2 stainless rod in demanding automotive or steel mill environments where precise end-stops are critical.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX50-50S the Right Cylinder?
Choose this 200 mm bore when your application requires maximum force in the 15000 N range, stepping up from the 160 mm bore which yields 10053 N at 0.5 MPa. The adjustable stroke is ideal for fine-tuning end positions during commissioning or product changeover without swapping the cylinder. You can replicate this exact configuration using a fixed SAI cylinder by matching the 200 mm bore, 50 mm stroke, PT port, SUS420J2 rod, and -S magnet.
The rear adjuster acts strictly as a travel stop, not a lock; it cannot hold loads without live air pressure. For load-holding without continuous air, consider an AirTAC SAIL or BSAI cylinder. Additionally, while the 40 mm rod handles high side loads, any stroke of 300 mm or more on this bore requires an external guide rod to prevent piston wear.
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 SAIJ200AX50-50S FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster screw lets you trim the effective travel window down from the 50 mm nominal stroke to any point within the 0-50 mm range. It functions as a hard stop for end-position tuning and does not lock the load without live air.
