About the Airtac SAI200 Standard Cylinder SAI200AX35S
The AirTAC SAI200X35-S is a double-acting ISO 15552 profile cylinder engineered for immense thrust, generating 15708 N of push force at just 0.5 MPa. Its short 35 mm stroke is tailored for high-force clamping, pressing, and heavy-duty holding tasks that demand maximum power in a compact movement range.
This configuration features a SUS420J2 stainless steel piston rod for enhanced durability against moisture and minor corrosion. Equipped with a built-in magnet (-S), it seamlessly integrates with CMSE and DMSE sensor switches housed in the dual-side grooves of the extruded aluminum barrel. Fluid ports utilize a PT tapered thread type.

Where the Airtac SAI200 Standard Cylinder SAI200AX35S Is Used
Heavy-Duty Stamping
Provides the robust 15708 N push force required for short-stroke metal forming, riveting, and impact stamping operations.
Industrial Clamping
Secures massive workpieces or molds in machining centers, utilizing its immense 200 mm bore power to lock heavy components firmly in place.
Injection Molding Ejection
Delivers high-impact ejection force to release dense molded parts from tooling, with CMSE sensors verifying the short 35 mm retraction.
Is the Airtac SAI200 Standard Cylinder SAI200AX35S the Right Cylinder?
Select this 200 mm bore actuator when 160 mm bore falls short, as the 160 class provides 10053 N at 0.5 MPa compared to the 15708 N offered here. Because the stroke is only 35 mm, side-load stress on the rod bearing is minimal, though external guides are still recommended if the load is asymmetrical.
For applications requiring the load to be mechanically held without continuous air pressure, note that the standard adjustable air cushions only decelerate the piston at stroke end and do not function as a lock. In those scenarios, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder. As a dimensionally interchangeable ISO 15552 unit, it serves as a direct drop-in replacement for other ISO 15552 profile cylinders, matching the 200 mm bore, 35 mm stroke, G3/4 port size, and standard mounting accessories.
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.
