SENSOR-EQUIPPED ROLLING BEARING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a sensor-equipped rolling bearing device which can be manufactured at low cost and has sufficient durability. SOLUTION: An oscillator 15 for transmitting ultrasonic waves toward a contact part 20 of a rolling element 5 to detect a force acting on the rolling element 5 is installed on an outer race 3 by resin molding, thereby reducing parts count and eliminating adhesive.
