Ⅰ. About Miniature ball bearing: We provide bearings without exceptional noise to ensure the silent running of the semiconductor device. Specially designed bearing shields are used to prevent the grease leaking, which may cause unexpected stop of the device. Moreover, we understand the concern about environment and energy saving.
Our precision deep groove ball bearings are designed for high precision, low noise, small vibration, high reliability and long life. They are mainly used in various types of electric motors. They are also known as EMQ (Electric Motor Quality) bearings.
