Nachi America BNH009TU/GLP4 Precision High-Speed Angular Contact Ball Bearing

Nachi America - BNH009TU/GLP4 High Speed Precision Angular Contact Ball Bearing. Balls and the inner ring and outer ring raceways are designed for contact in a specific contact angle, which means this type of bearing is suitable for composite loads (axial load and radial load). The contact angle means that axial force components are generated when a radial load is applied, so these are normally used in pairs at either end of a shaft. A contact angle of 15° is standard. Since ball slipping is reduced by the gyro-moment at high-speeds, the ball diameter of this type of bearing is smaller than that of a standard angular contact ball bearing.

Features

With angular contact ball bearings, the balls and the inner ring and outer ring raceways form a specific angle of contact. When used in a single configuration, axial load is limited to a single direction, this type of bearing is suitable for bearing composite loads made up of axial and radial loads. Since this type of bearing has a contact angle, axial components are generated when a radial load is applied. Becasue of this, this type of bearing is normally used in pairs at either end of a shaft. Smaller machine steel balls, higher speeds, and lower temperatures than previous angular contact ball bearings. Maily used for the main spindle of high-speed machining centers.
