The AirTAC AirTAC SAI200X135-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 135mm 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 SAI200X135-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. It provides a formidable push force of 15708 N at 0.5 MPa and a pull force of 15080 N, making it well-suited for moving substantial masses over its 135 mm stroke. The extruded aluminum barrel design omits traditional tie rods for a clean, robust exterior.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in harsh environments. It includes a magnet (-S) for direct compatibility with CMSE and DMSE sensor switches, which seat neatly into the dual grooves on the barrel. Fluid ports feature PT tapered threading, and the cylinder supports an operating speed of 30-500 mm/s.

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.
Generates the 15708 N force required to seat bearings or stamp thick-gauge metal components securely in automated fabrication lines.
Utilizes the SUS304 rod and robust 200 mm profile to safely eject heavy plastic injection molds exposed to high heat and humidity.
Provides reliable linear actuation for hydraulic-free pneumatic press systems requiring massive, consistent clamping force over 135 mm.
Selecting this 200 mm bore unit is ideal when applications demand extreme thrust that smaller bores cannot provide, such as lifting heavy molds or pressing assemblies. If the 15708 N at 0.5 MPa is excessive for your application, stepping down to a 160 mm bore offers 10053 N, providing a more energy-efficient alternative.
Because the stroke is 135 mm, side-load risks are moderate, but ensuring proper mounting alignment remains critical to prevent premature rod-bearing wear. For tasks requiring position holding without continuous air pressure, note that the standard adjustable air cushions only decelerate the piston at stroke ends; a SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant is required to prevent drifting.
Quick checklist
At 0.5 MPa operating pressure, this 200 mm bore cylinder delivers a push force of 15708 N and a pull force of 15080 N. It can achieve a theoretical maximum push force of 21991 N at 0.7 MPa.
Yes, the -S suffix indicates a built-in magnet, allowing seamless integration with CMSE and DMSE sensor switches in the barrel grooves. Additionally, this unit features PT tapered fluid ports sized at G3/4.
