Angular Contact Ball Bearing >> 7000AC Series < Online Inquiry >
Features
Individual bearings of this type are capable of taking radial loads and also axial loads in one direction. Four contact angles of 15, 25, 30, and 40 are available. The larger the contact angle, the higher the axial load capacity. For high-speed operation, however, the smaller contact angles are preferred. Usually, two bearings are used in duplex pairs, and the clearance between them must be adjusted properly.
Pressed steel cages are commonly used, however, for high precision bearings with a contact angle less than 30, polyamide resin cages are often used.
Applications
These bearings are mainly applied in the machine tool spindles, high-frequency motors, gas turbines, oil pumps, air compressors, printing machines and other installations.
