FIELD: measuring technique.

SUBSTANCE: device comprises flexible measuring member mounted concentrically with respect to the bearing race and having strain gauges covered with casing and set on its surface. The device also has split bushing with conical outer side mounted for permitting cooperation of the inner side of the flexible member with the outer side of the bearing race to be tested. The flexible member is sectional and composed of two step thick-walled races provided with strain gauges, mounted on the bushing, and interconnected by means of a thread joint. The bushing has ring cylindrical recess centered in its outer surface. The inner surfaces of the smaller steps of the thick-walled races are conical, with cone bases arranged from the side of the large steps.

EFFECT: enhanced convenience of testing and reduced metal consumption.
