Rolling element for rolling bearing, has body comprising shell that rests against outer surface of insert under radial bias, and insert made form resilient material i.e. plastic, where element is designed as needle-like shaped structure

摘要

The element has a body (1) comprising a shell (2) that rests against an outer surface of an insert under a radial bias, where the insert is made form resilient material i.e. plastic. Edges (8, 9) of a slot (7) of the shell are received at the outer surface of the insert. The insert comprises magnetic particles and porous material i.e. foam material, and is designed as over molding. A function layer comprises electrostatic, oleophilic, hydrophilic or hydrophobic properties, where the element is designed as a needle-like shaped structure.
