Zusammenfassung:	FIELD: mechanic assembling production, namely direct testing of strength of interference joining of parts of formed joints. SUBSTANCE: apparatus includes elastic member mounted concentrically relative to bearing race and having on its surface strain-sensitive resistor elements closed by casing. Elastic member is in the form of sleeve with cone inner surface and it has on its outer cylindrical surface (in mean portion of said surface) annular turning on bottom of which high temperature strain- sensitive resistor elements under protective casing are placed. At side of large diameter of cone surface of elastic member, internal thread is formed on length portion of elastic member. Apparatus includes slit type fastening sleeve with cone outer surface mounted with possibility of engagement of inner surface of elastic member with outer surface of race of bearing assembly. EFFECT: enhanced reliability of evaluated strength value of heat pressing of bearing races onto journals of paired wheel axles. 3 cl, 1 dwg
