About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX110-50S
The AirTAC SAIJ200X110-50-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty tasks, featuring a rear stroke adjuster that creates a 60-110 mm usable travel window from its 110 mm nominal length. Delivering a robust 15708 N of push force at 0.5 MPa, this unit handles massive payloads without relying on external stops. The extruded aluminum barrel integrates dual sensor grooves, allowing precise positioning feedback via CMSE reed or DMSE electronic switches.
This configuration features a SUS420J2 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end during commissioning; it does not lock the load, meaning live air pressure is required to maintain position. For applications needing true fail-safe holding without pressure, exploring the SAIL or BSAI series is recommended.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX110-50S Is Used
Heavy Pressing Operations
Apply up to 21991 N of thrust at 0.7 MPa for assembly tasks, using the 50 mm adjuster to fine-tune the exact pressing depth on varying product heights.
Machine Changeover
Rapidly adapt the retract end-stop from 60 to 110 mm during production line shifts, eliminating the downtime required to physically swap out cylinders for different part sizes.
Automated Forming
Utilize the robust 40 mm SUS420J2 stainless steel rod in high-wear forming stations, benefiting from the ISO 15552 mounting interface for seamless integration.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX110-50S the Right Cylinder?
Selecting this 200 mm bore model is ideal when your application demands the highest thrust class, offering 15708 N push and 15080 N pull at 0.5 MPa. If the load requirement drops, stepping down to a 160 mm bore provides 10053 N of push force, which might offer a more compact footprint. The 50 mm adjustment range is particularly valuable for product changeovers, letting operators dial in the exact end-stop without physically swapping the cylinder.
Because the stroke is 110 mm, an external guide is not strictly mandated for side-load management, though the substantial 40 mm rod diameter inherently withstands moderate deflection. When matching this ISO 15552 dimensionally interchangeable cylinder, verify the PT port threads, SUS420J2 rod material, and the -S magnet for CMSE/DMSE sensor compatibility. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

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 SAIJ200AX110-50S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. If higher pressure is available, it can deliver up to 28274 N of push force at 0.9 MPa.
The rear mechanical stopper allows you to shorten the 110 mm nominal stroke by up to 50 mm, creating a usable travel window between 60 mm and 110 mm. This adjuster sets the retract end position but does not lock the load without continuous air pressure.
