About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX160-50S
The AirTAC SAIJ200X160-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the effective travel by up to 50 mm. This creates a usable 110-160 mm adjustable window for precise end-position tuning at commissioning without swapping hardware. It delivers massive thrust, providing 21991N of pull force at 0.7 MPa and 28274N of push force at 0.9 MPa.
This variant features a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and includes a magnet for position sensing with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered port threads ensure a tight, reliable pneumatic connection in demanding industrial environments.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX160-50S Is Used
Heavy Press End-Tuning
Dial in the exact 110-160 mm pressing distance during machine commissioning to accommodate varying material thicknesses without adding external stops.
Product Size Changeover
Quickly adjust the retract end-position on packaging lines when switching to a different product size, leveraging the 50 mm trim range for rapid setup.
High-Force Positioning
Utilize the 28274N push force at 0.9 MPa to move heavy assemblies into place, using the rear screw to fine-tune the final resting coordinate.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX160-50S the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires extreme force combined with variable end-stops for product changeovers. If you need less thrust, stepping down to a 160 mm bore yields 9425N of pull force at 0.5 MPa, which may better suit lighter loads. The adjustable rear screw acts purely as a mechanical stop to set the travel end; it does not hold the load without live air pressure. For true load-holding requirements, consider an external rod lock, or explore the SAIL or BSAI cylinder series.
As a dimensionally interchangeable ISO 15552 cylinder, this model uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the 160 mm stroke is below the 300 mm side-load threshold, no external guide is strictly required, though the robust 40 mm rod and M36x2 thread handle substantial side loads natively.
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 SAIJ200AX160-50S FAQ
The rear adjuster acts as a mechanical stop that shortens the nominal 160 mm stroke by up to 50 mm, providing an effective travel window of 110-160 mm. It sets the end position but does not lock or hold the load without continuous air pressure.
At 0.5 MPa, it provides 15708N of push force and 15080N of pull force. At 0.9 MPa, the push force increases to 28274N, and the pull force reaches 21991N.
