A heavy-duty, short-stroke hydraulic cylinder designed for the extreme conditions inside wind turbine nacelles and hubs. At 140 kg with a \u03a6150 mm mounting pin, this cylinder is built for the continuous vibration, extreme temperatures, and 20+ year service life demanded by the wind energy industry. The compact 80 mm stroke provides precise control for blade pitch adjustment and yaw braking \u2014 the two most critical hydraulic functions on a wind turbine.<\/p>\n<\/section>\n

How Hydraulic Cylinders Control Wind Turbines<\/h2>\n
<\/div>\n

\"Wind<\/p>\n

Wind turbines use hydraulic cylinders for two primary functions: blade pitch control and yaw braking. Blade pitch cylinders rotate each blade around its longitudinal axis \u2014 adjusting the angle of attack to control rotor speed and power output. Yaw brake cylinders apply friction pads against the yaw bearing ring \u2014 holding the nacelle at the correct wind angle.<\/p>\n

The EP-WP wind power cylinder’s short 80 mm stroke and heavy 140 kg construction reflect these applications. Pitch and yaw functions require high force over minimal displacement \u2014 the cylinder pushes hard through a short distance, then holds position under constant load. The \u03a6150 mm pin diameter provides the structural connection strength needed for the extreme bending moments at the blade root or yaw ring.<\/p>\n

Wind turbine cylinders must operate maintenance-free for years at a time, 80\u2013100 metres above ground, in temperatures from -40\u00b0C to +60\u00b0C, under continuous vibration from the rotor. The 16 MPa working pressure at \u03a6100 bore produces approximately 126 kN of force \u2014 sufficient for pitch and yaw control on turbines up to 3 MW.

\u03a6150 Pin \u2014 Structural Load Path<\/strong><\/p>\n

The oversized \u03a6150 mounting pin is 50% larger than the \u03a6100 bore \u2014 because the pin transmits the full blade root bending moment or yaw braking torque. The pin is the structural interface between the cylinder and the turbine structure.<\/p>\n<\/div>\n

\n

80mm Stroke \u2014 Force, Not Travel<\/strong><\/p>\n

Blade pitch and yaw braking require high force over minimal distance. The 80 mm stroke provides precise angular control (pitch) or pad engagement (yaw) without the weight and complexity of a longer-stroke cylinder.<\/p>\n<\/div>\n

\n

140 kg \u2014 Built for Decades<\/strong><\/p>\n

The heavy construction reflects the 20+ year design life. Thick-wall tube, massive end caps, and oversized seals are specified for the continuous vibration, thermal cycling, and corrosive (humidity + salt air on offshore turbines) environment inside the nacelle.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Frequently Asked Questions<\/h2>\n
<\/div>\n
\n
\n

Can this cylinder be used on offshore wind turbines?<\/h3>\n

The cylinder is suitable for both onshore and offshore applications. For offshore installations, Korea Ever-Power can supply enhanced corrosion protection (marine-grade chrome plating, special seal materials) on request. Contact the team with your turbine model and environment.<\/p>\n<\/div>\n

\n

What is the \u03a6150 pin for?<\/h3>\n

The \u03a6150 pin is the structural mounting connection \u2014 significantly larger than the \u03a6100 bore because it must transmit the full blade root bending moment or yaw braking torque through the cylinder mount. The pin is typically hardened steel, ground to a precision fit.<\/p>\n<\/div>\n

\n

How often does the wind power cylinder need maintenance?<\/h3>\n

Wind turbine cylinders are designed for maintenance intervals of 5\u201310 years. Inspection during scheduled turbine maintenance (typically annual) should check for oil leakage, rod surface condition, and pin wear. Full cylinder replacement is typically at 15\u201320 years.
