The BARDEN range of angular contact ball bearings are ideally suited for high speed applications where both axial and radial loads are to be supported, and system rigidity requires preloading. They have a nominal contact angle ranging from 10° to 25°and are available with machined phenolic cages and with separable (B type) or non-separable (H type) outer ring. The H type non-separable bearings (offered in 1900HC, 100HC, 200HC and 300H series)  use a larger complement of balls than is possible in the same size deep groove bearings resulting in a greater capacity and higher speeds because of the phenolic one-piece cage. The B type separable angular bearings utilize cages to retain the balls when the outer ring assembly (including cage and balls) is separated from the inner ring. This type of bearing has the same high speed capability as the H type bearing providing advantages for certain applications. Separable bearings simplify assembly of units where bearings are located in blind holes. The separable feature also permits dynamic balancing of a rotating component with inner rings mounted in place, apart from the outer ring and housing.
