A single-action freewheel with an open diameter greater than 50 mm and with an inner and outer ring. The object is to provide an open central diameter of more than 500 mm while allowing high torques in a freewheel that can be made without consuming much material. The invention is charaterized by two or more rows (3 & 4) of shoes or jaws between the inner ring (1) and the outer ring (2) with normal clutching forces tht act more or less on one plane (13) or diameter, by one or more revolving webs (6) connected to the rings and extending between the rows, and by an activating mechanism (9) that approximately simultaneously tightens and loosens the shoes.

Single-action freewheel clutch with substantially large central diameter

A large roller bearing in the form of a wire bearing with at least one row of rollers accommodated between rings and rolling around a race made out of wires, whereby at least one row of rollers is resiliently secured by a ring or by part of a ring, characterized in that a race wire rests against a spring disk (9) that is at least partly slit radially and that is secured to a bearing ring by a continuous or segmentally divided retaining ring (11), with a space (13) between the spring disk and the retaining ring in the vicinity of the race.
