Roller bearing, has roller element rolling on pitch line of bearing ring, and lubrication tube carrying lubricant to lubrication element that is located on bearing ring, where lubrication element is arranged at sides of pitch line

摘要

The bearing has a roller element (3) rolling on a pitch line (2) of a bearing ring (1). A dimensionally stable lubrication element (4) is made of a porous material that contains a lubrication material. A lubrication tube (8) carries the lubricant to the lubrication element that is located on the bearing ring. The hollow-cylindrical lubrication element is arranged at sides of the pitch line. A molded part (5) temporarily remains in contact with the roller element. The molded part is located on a form-fitting surface extended to an inner circumferential surface of the bearing ring.
