Patent ID: 7798717

Claim:
A spacer for roller bodies which are guided in a roller bearing and which have an axis of symmetry defining a rolling axis about which they roll in a revolution path of the roller bearing, the spacer comprising: two diametrically opposed, spaced-apart end parts which are each located transversely to a direction of motion of the roller bodies and have contact faces for rolling faces of the roller bodies; two diametrically opposed, space-apart lateral parts, wherein each of said lateral parts connects said two end parts, has a plate shape with a first side extending transversely to the rolling axis of the roller bodies for contact with the roller bodies and second, short sides extending substantially in a direction of the rolling axis of the roller bodies, and is stiffened with regard to bending substantially orthogonally to the rolling axis of the roller bodies so that in motion along the revolution path, each of said lateral parts essentially maintains its shape; and at least one rib connecting said two lateral parts between said two end parts and having contact faces for the rolling faces of two successive ones of the roller bodies, wherein said lateral parts extend in curved fashion between said two end parts, and wherein said curved lateral parts have one uniformly extending inner long edge and one outer long edge which is uniformly curved, beginning at face ends of a respective one of said lateral parts, and changes into a flattened middle part, and a shape of said lateral parts is mirror-symmetrical to a center plane between said end parts, and radii of curvatures are dimensioned such that said lateral parts in all portions of the revolution path are engageable with a guide groove provided in side walls of said revolution path.
