Duplex angular contact ball bearings HT series
Duplex angular contact ball bearings HT series are a matched set of angular contact bearings mounted in pairs. Depending on the duplex type, they can handle combined radial and axial loads in either one or two directions. The inner and outer ring raceways are offset to each other, resulting in a shoulder on the inner raceway rings.
Duplex angular contact ball bearings HT series have a greater number of balls and higher capacities than deep groove ball bearings with the same boundary dimensions and are suitable for higher loads and speeds with proper lubrication. However, because of the absence of a flange on one side of the outer race, they are capable of supporting thrust loading in only one direction. This is why most applications employ two of the same bearing bearings facing opposite directions, often as a duplex pair. To obtain American BAC bearings capable of duplex mounting, they must be ordered “flush ground”, designated by the “G” suffix. “G” basically means “No axial clearance, no preload.” In cases where the tandem mounting is required, another bearing with thrust capability is usually employed on the shaft to take thrust or locate the shaft in the opposite direction as the pair.
