The sidewall has edges closed by disks (4, 4'), where each disk has an axial opening for passage of arbor (7). Height of the housing ranges between 85 percentage and 97 percentage of total height at periphery of the barrel. One of the disks has thickness ranging between 0.04 and 0.12 mm. The opening is encircled by annular projection (6) connected to a surface of the disk that is formed from silicon, quartz and diamond.
