The AirTAC AirTAC SAI200X850 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 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty industrial automation. Delivering a substantial 15708 N push force at 0.5 MPa, this 200mm bore actuator handles massive payloads with reliability. The 850mm stroke provides the extended travel distance needed for large-scale material handling and press operations.
This model features a standard carbon steel piston rod and PT tapered port threads, ensuring robust mechanical performance under high stress. While the extruded aluminum barrel includes dual sensor grooves, positioning requires a separately specified magnet (-S) to utilize CMSE or DMSE switches. For applications needing precise end-position stopping under extreme weight, the BSAI bidirectional clamp-lock variant offers enhanced safety.

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 immense 15708 N push force required to drive large metal forming presses and heavy-duty stamping dies across extended 850mm cycles.
Actuates large-scale bulk material gates and heavy diverter arms on mining or aggregate conveyor lines where massive thrust is mandatory.
Clamps heavy structural components and large fabricated frames within automated welding jigs, utilizing the full stroke length for deep part clearance.
Selecting this 200mm bore actuator is ideal when 160mm hardware lacks sufficient thrust, moving from 10053 N up to 15708 N at 0.5 MPa. Because the 850mm stroke creates a long unsupported rod extension, side-load forces can cause severe rod-bearing bending and premature wear. Implement external guide rails or switch to a fully guided cylinder to protect the actuator in high-deflection setups.
As a true ISO 15552 profile cylinder, it serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 profile cylinders. Matching this exact unit requires a 200mm bore, 850mm stroke, G3/4 PT ports, and compatible FA/FB flange or TC trunnion mounts. Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold loads. If pressure drops, the rod will drift, requiring an external pilot-operated check valve for position holding.
Quick checklist
At a 0.5 MPa operating pressure, this 200mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X850 is a genuine ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other ISO 15552 standard cylinders. Ensure your setup matches the G3/4 PT ports and 850mm stroke.
