NTN Develops "The Industry's First" Bearing with Built-in IC Tag

Entien developed bearings with built-in IC tags to record quality information and usage history. In the future, it will be recommended for use in machinery in various fields such as construction machinery, mining machinery, aircraft, railway vehicles, and wind turbines.

Through the use of IC tags, the quality information at the time of delivery (various bearing sizes, production dates, serial numbers, etc.) and the use history after supply (product information with bearings, time of use, inspection results, etc.) can be recorded. On the bearing. As for what information is recorded, it can be set according to the customer's needs.

When an IC tag is mounted on a metal such as a bearing inner ring, it is generally difficult to read or write due to metal influence. For this purpose, Entien developed a new reading and writing device that can also be read and written on metal.

The newly developed bearing has a 4.5mm diameter hole on the side of the inner ring (the bottom surface of the ring), and the IC tag is embedded therein. The IC tag is completely embedded inside, so the bearing size is the same as the existing product and can be easily replaced. Although it depends on the wall thickness of the bearing, the IC tag can be disposed as long as the bearing has an outer diameter of 180 mm or more. Bearing built-in IC tag "is still the first time in the industry" (Entien).
