A roller assembly includes a body (10) with a cylindrical bore (12) and rollers (14) extending lengthwise inside the bore. The rollers abut one another to form a closed circle of rollers. …<??>A folded spring (18) extends diametrically across the circle of rollers with diametrically opposite ends (20,22) pressing between two adjoining rollers to wedge these rollers apart circumferentially and thus to press all the rollers against the surface (16) of the bore (12) in a "keystoning" effect with sufficient force to prevent axial movement of the rollers and to radially retain the rollers in the body. The spring is arranged to be subsequently pushed axially from the body. |
