Abstract

A bearing device for a wheel, which can be easily traced after it is shipped from a factory, in which a lot number and quantity of a product including the bearing device can be easily specified when inspection or replacement is required after the shipment, and whose quality control can be quickly and easily performed. A bearing device for a wheel, having an outer ring member (3), an inner ring member (5) provided radially inside of and concentrically with the outer ring member (3), and rolling bodies (6) arranged between the outer ring member (3) and the inner ring member (5). An ICchip (20) is provided at the bearing device at a vehicle-outer-side end section or at a vehicle-inner-side end section.

Description

technical field [0001] The present invention relates to a bearing device for a wheel (hereinafter also simply referred to as a bearing device). Background technique [0002] The wheel bearing unit is used to rotatably support the wheel on the vehicle body. In order to identify the product, the date of manufacture or size can be engraved on the bearing unit at the factory shipment stage, or it can be marked with a laser. [0003] However, for various reasons, after the bearing unit is completed, when it is kept in a warehouse as stock, or in the distribution stage, or when it is assembled into a final product and launched, it is necessary to inspect or replace the bearing unit. It is important to specify the serial number, lot number, and quantity of the bearing unit. However, as the current situation, only the date of manufacture or the size information is added to the product as described above, and it is expected that it will take time to perform the above identification. ...
