Abstract

Running surfaces (3, 6) of inner and outer rings (2, 5) are given a wear-resistant coating. Lubricating grease is included between them. This is insoluble in fuels, especially petrol, paraffin and diesel oil. The seal (7) is fastened to the inner or outer ring. It either contacts one of these with sealing lips (9), or leaves a gap.
