Home appliances update: sintered bearing self-lubrication and its impact on motor performance

Designing for maintenance-free operation

Engineers seeking reliable, maintenance-free solutions in home appliance design often turn to graphite-impregnated sintered bronze bearings. These components conform to international standards. The technology is based on Powder Metallurgy, where producers can control powder characteristics such as purity, hydrogen loss, particle size and distribution, and particle shape. Each of these properties affects performance in some way.

Application-specific material selection

In the electrical and electronics segments of home appliances, components like small motors are common. A low-oil-content, low-porosity material with a high graphite content is more satisfactory for oscillating and reciprocating motions where it is hard to build up an oil film. This makes it suitable for demanding, high-cycle applications. In the bronze system, shrinkage increases as particle size changes.

Common appliance applications

These bearings are used in a wide variety of areas including automobiles, home appliances, and digital products. Specific household applications include washing machine drum drives, vacuum cleaner motors, stand mixer drives, air conditioning fan motors, and robotic systems. Their compact, maintenance-free nature fits the design constraints of modern appliances.
