  • Place the gauge (marked „coupling ball 50“) onto ball50 in driving direction. The gap between the gauge and the edge of the ball shows the degree of wear. The smaller the gap, the closer the ball is to its wear limit. Nominal dimension ball 50: 50 mm, max. wear of 1 mm, wear limit: 49 mm.
  • The ball50 has reached the wear limit when the gauge encloses the ball completely.

  • Place the special tool (marked „coupling head 50“) into the calotte. Use the flashlight to light up the inner zone of the calotte. Make sure that the special tool is positioned in the direction of travel. The gap between the gauge and the surface of the calotte indicates the wear limit. The smaller the gap, the closer the calotte approaches its wear limit. Nominal dome size: 50 mm, max. wear limit of 1.0 mm, 41.0 mm.
  • The spherical cap has reached the wear limit when the gauge touches the center of the spherical cap.
