Abstract
The construction is designed of the radial compaction with perfected springy characteristic. The compaction allows to use it drilling bit with two and more frictionless bearing. Laboratory tests have shown more low factors of the abrasion of the seal assembly than serial. The compaction can be used in the system of forced lubrication of the drill bit it will allow else more reduce the velocity of the abrasion and provide the working-off of bit under raised frequency of the rotation.
