In figures 4 and 5, the ceramic unit (7) is shown in detail. The ceramic unit (7) consists of two hollow cylindrical parts (8). On one side of each half (8), there exits a number of ball sockets (9) (preferably six ball sockets). Six balls (11) are housed in between the two halves (8) of ceramic unit (7), within these ball sockets (9), forming a type of "ball bearing". These two halves (8) of ceramic unit (7) are glued together with heat resistant glue; making sure that the glue does not get close to the balls (11); after the balls (11) are placed in between them (8). In addition to glue, the Ceramic halves (8) are also bolted (10) together for additional strength. The balls (11) are preferably made up of ceramic, but other materials can also be used.

Thanks in advance!!
