A conventional free action bearing, comprising a combination of a small rolling ball and a main ball, can not be used as a load transmission bearing for a shroud-equipped rotating blade or an electromagnetic rim-speed-utilizing wind power generation device due to the extremely low allowable speed. The allowable speed of a free action bearing that does not use a small rolling ball and uses only either a ball or a roller can be made at least 40 m/s by: opening tiny holes in the socket of the free action bearing; providing a bottom cap on the bottom of a cage on the side of an object to which the free action bearing is mounted; filling a lubricant chamber in the space between the socket and the bottom cap with a lubricant/additive; and setting up a relative positioning such that the outside of the socket with tiny holes is immersed in the lubricant/additive in the lubricant chamber. The lubricant/additive then seeps from the outside of the socket to the inside of the socket, where the ball or roller is, and the ball or roller can glide on a lubricant/additive film.
