About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX115-50S
The AirTAC SAIJ200X115-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 65 to 115 mm, allowing you to dial back the nominal 115 mm stroke by up to 50 mm during commissioning. In the 200 mm bore class, it delivers 15708 N of push force at 0.5 MPa and reaches a maximum of 3204 kgf at 1.0 MPa.
This unit features a SUS420J2 stainless steel rod (option A) for corrosion resistance and includes a magnet for position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. Pneumatic connections use PT tapered ports sized at G3/4.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX115-50S Is Used
Heavy Press Tuning
Dial in the exact 65 to 115 mm end position for large stamping or pressing tasks without swapping out the entire cylinder.
Product Changeover
Quickly adjust the retract stop on a production line to accommodate different large product sizes during format changes.
Assembly End-Stops
Set precise lower endpoints for heavy automotive or industrial component assembly without adding external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX115-50S the Right Cylinder?
Choose this 200 mm bore when an application requires substantial thrust, such as 15708 N at 0.5 MPa, combined with variable end-stop positioning. If a fixed end position is sufficient and you need less force, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa. The rear adjuster acts purely as a mechanical stop to fine-tune the travel end; it does not hold the load without live air. For true fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder instead. Because the 115 mm stroke is relatively short for this large bore, side-load risks are minimal, but an external guide is still recommended for heavy masses. SAIJ 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 SAIJ200AX115-50S FAQ
An external adjusting screw at the rear acts as a mechanical stop, allowing you to shorten the effective stroke from 115 mm down to 65 mm. This provides a 50 mm tuning window for fine-tuning the end position without replacing the cylinder.
At the maximum operating pressure of 1.0 MPa, the 200 mm bore generates a maximum push force of 3204 kgf. At a standard 0.5 MPa, it provides 15708 N of thrust.
