Process for producing a seal running surface on a bearing ring and large roller bearings

摘要

The present invention relates to a method for producing a circumferential seal running surface (1) on a bearing ring of a large roller bearing, the seal running surface (1) being machined in a first step by turning and the machined surface then being given a predetermined surface roughness by grinding using a grinding wheel (2) receives. In order to specify a manufacturing method for a circumferential seal running surface on a bearing ring of a large roller bearing, which leads to large roller bearings with improved tightness, it is proposed that the grinding wheel perform an oscillating movement relative to the seal running surface (1) during grinding, the oscillating movement executing the entire axial width of the Seal running surface (1) covers, and the oscillating movement of the grinding wheel (2) takes place in such a way that a surface structure introduced into the seal running surface (1) by the rotation, through which lubricant escapes from the interior of the bearing during the rotation of the bearing is at least neutralized.
