  • the subdivision of the sliding block 10 into a sliding part 31 is essential to the invention a material with good sliding properties and a support body 30 made of one material high mechanical strength. Since only the material for the sliding part 31 Sliding properties, but not the requirements for mechanical strength in the The foreground and vice versa for the material of the support body are mechanical Strength with respect to tensile and bending stress is essential Sliding properties are insignificant due to the lack of contact with the sliding surface 20, This creates greater scope for the targeted selection of suitable materials low specific weight. Both for the sliding part, but especially for the Support bodies can use materials that are opposite one conventional glide shoes have a significantly lower weight. Thereby the weight of the entire sliding shoe 10 can be significantly reduced overall, which causes a reduction in the centrifugal force acting on the sliding block 10.
