Horizontal axis - front loading washing machines

The drum is supported usually by two single row deep groove ball bearings or, when space is a constraining factor, by a Hub Bearing Unit. The drum is overhung in respect to the two support bearings. The out of balance load is predominantly taken by the bearing closest to the drum. Therefore this bearing tends to be larger than that on the pulley side.

SKF single row deep groove ball bearings

The ball bearings commonly used have metal shields and an internal radial clearance dependent on the press-fit required and material of the housing. For high speed washers (over 1 000 rpm) special greases with extreme pressure additives are used to withstand the higher unbalanced loads and vibrations. The bearing closest to the drum is usually protected against water/humidity by a static and dynamic seal. SKF can provide a wide range of static and dynamic seals. Special seals can be manufactured on the basis of design requirements.
