NTN Corporation has developed a new hybrid grease-filled bearing that is long-lasting at high temperatures, for use in automotive electrical instruments and other devices.
In recent years, bearings for automotive electrical instruments are being used in increasingly severe environments. In order to ensure the lifetime grease in high-temperature environments, older greases used thickening agent and base oil made of fluorinated compound. The newly developed NA204F hybrid grease, however, consists of a mixture of fluorine and urea grease in an optimum ratio. Also included are appropriate amounts of anti-rust and extreme pressure agents. This enables the grease to last longer than existing fluorinated grease at temperatures of 200
