This article devoted to the thermoeffect of the entrance zone. It is describe a method for calculation the temperature of a lubricant, which enter to the zone of contact, for determination the temperature coefficient, and a method for calculation thickness of the lubricating layer, which separate the friction surface. The actual value of the lubricating layer in the contact is very meaningful for analysis of the functionality of the rolling bearing.
