Track for ball channel in ball bearing-linear guide, is formed such that on track surface two predefined contact areas are provided on track for ball rolling between track surface and upper surface of shaft

摘要

The track (34) is provided in a retainer such that a track surface (35) facing the circumferential balls (13) faces into interior of the retainer. The balls rolls on the track surface between the track and an upper surface (36) of a shaft (26), where the track is formed such that on the track surface two predefined contact areas (38-1,38-2) are provided on the track for the ball rolling between the track surface and the upper surface of the shaft. The ball rolls on the contact areas and the surface (42) of the track facing a bearing casing bore. An independent claim is included for a method for operating a linear guide.
