NTN developed a bearing with built-in IC label, thereby can record the bearing's quality information and using curriculum vitae. In the future will recommend it to the construction machinery, mining machinery, aircraft, railway vehicles, wind turbines and other fields of machinery to use.
By equipped with IC label,quality information ( bearing's various size, production date, serial number and so on ) and using curriculum vitae after supplying (product information of equipped bearing, date of putting into use and examination results ) will be recorded in the bearing when provide products. As for what information to record, it is according to the needs of customers.
When mounted IC label on the inner ring of the bearing, due to metal effects, it is difficult to read and write. So NTN developed a new read-write equipmentwhich can read and write on metal.
In the inner side of the new developed bearings (the bottom surface of the torus ), there opened a hole of 4.5mm diameter, here embedded the IC tags. For the IC tag is completely embedded in, so the new bearing's size has no difference from the existing product's, they can exchange easily. Though it has relation with the bearing wall thickness, as long as the outside diameter of the bearing is in 180mm or above, the IC tag can be equipped.And Bearing built-in IC tag is "the first time in the industry"
