The AirTAC AirTAC SAI200X85 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 85mm 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 SAI200X85 is a double-acting ISO 15552 profile cylinder featuring a 200 mm bore and an 85 mm stroke. Because 85 mm is outside the standard incremental strokes, this is a made-to-order unit. It delivers substantial thrust, generating 15708 N of push force and 15080 N of pull force at 0.5 MPa. The extruded aluminum barrel omits traditional tie rods, providing a clean exterior while maintaining strict dimensional interchangeability per ISO 15552.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A), offering superior corrosion resistance compared to standard carbon steel. It uses PT tapered port threads and lacks a magnet, meaning it is not compatible with CMSE or DMSE sensor switches without modification. For applications requiring end-position holding under pressure loss, consider the BSAI bidirectional clamp-lock variant.

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 15708 N push force at 0.5 MPa required to form thick-gauge sheet metal in automated stamping presses.
Secures heavy injection molds during setup, utilizing the SUS420J2 stainless rod to resist workshop humidity and coolant splashes.
Drives large bearings into automotive housings, using the adjustable air cushions at both ends to prevent impact damage at stroke completion.
Selecting this 200 mm bore actuator is ideal when 15080 N of pull force at 0.5 MPa is required, but stepping down to a 160 mm bore (9425 N pull at 0.5 MPa) is preferable if lowering air consumption is a priority. Because the 85 mm stroke is non-standard, expect a slightly longer lead time for made-to-order fulfillment. The PT thread type ensures a robust, sealed pneumatic connection.
If your machinery must hold a load vertically without continuous air pressure, a standard SAI cylinder will drift downward when air is exhausted. You must integrate an external pilot-operated check valve or switch to the SAIL air-released lock variant. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 actuators of the same bore, matching standard TC, CA, and FA mounting accessory dimensions.
Quick checklist
At a 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X85 is a genuine ISO 15552 profile cylinder. Its mounting interface dimensions are fully interchangeable with other ISO 15552 standard actuators of the same bore size, allowing for seamless retrofitting.
