Abstract
The design has a radial seal with improved spring properties. The seal allows its use in drill bits with two or more bearings without friction. Laboratory tests have shown lower abrasion coefficients of the sealing unit compared to serial ones. The compaction can be used in the system of forced lubrication of the drill bit, which will further reduce the rate of abrasive wear and ensure the bit operation at increased rotational speed.
