The AirTAC AirTAC SAI200X850-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 850mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAI200X850-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 15708 N of push force at 0.5 MPa, this 200 mm bore unit is built to move substantial masses. The 850 mm stroke handles extended travel requirements, and the integrated magnet allows direct mounting of CMSE or DMSE reed sensors along the extruded aluminum barrel grooves.
Configured with a standard carbon steel piston rod and tapered PT ports, this model ensures reliable sealing and high structural integrity. It is a genuine AirTAC component, dimensionally interchangeable per ISO 15552 standards, making it a seamless drop-in replacement for other cylinders sharing the same mounting interface.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Provides the high clamping thrust required to hold large steel plates securely during heavy-duty stamping and bending operations.
Drives large-scale robotic welding fixtures and heavy component positioning platforms demanding long 850mm travel and extreme force.
Actuates massive diverter gates and heavy-load lifting mechanisms on high-capacity aggregate or mining conveyor lines.
With a maximum theoretical force of 3204 kgf at 1.0 MPa, stepping down to a 160 mm bore reduces the 0.5 MPa push force to 10053 N, which may be insufficient for massive loads. For this 850 mm stroke, the unsupported rod length is substantial; always use an external guide or a guided cylinder carriage to prevent rod-bearing bending under side loads. If the machinery requires the load to be physically held in place without live air pressure, specify a SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead of a standard cylinder.
To match this ISO 15552 footprint exactly, pair the 200 mm bore, 850 mm stroke, G3/4 PT ports, and an appropriate mounting accessory like the TC trunnion or CA clevis. The -S suffix confirms the magnet is installed for position sensing.
Quick checklist
At 0.5 MPa it provides 15708 N of push force and 15080 N of pull force. The theoretical maximum force is 3204 kgf at 1.0 MPa.
Yes, the SAI200X850-S is dimensionally interchangeable per ISO 15552. Match the 200mm bore, 850mm stroke, and G3/4 ports for a direct drop-in replacement.
