Because it is delivered as a single unit, manufacturers need fewer assembly operations and no machining to fit it into the washing machine.
The unit supporting the drum, which is delivered with integrated bearings, greased and sealed for life, can be over-moulded by washing-machine manufacturers directly into their plastic tanks.
Claimed to be lightweight and corrosion proof, the design has a hole to drain out excess water, moisture and humidity that may arise inside the tank. According to SKF, the external unit’s shape and dimensions can be adapted to any washing machine design.
As an option, the unit can also be equipped with low-friction seals and energy-efficient bearings.
Engineers at SKF have developed a polymer-based drum support unit for washing machines
