A white metal bearing is a type of bearing made of an alloy of tin, copper, and antimony. This alloy has a white appearance, hence the name "white metal". White metal bearings are often used in heavy machinery and industrial equipment where they support the shaft or rotor and reduce friction and wear between the rotating parts.
White metal bearings are commonly used in applications where high loads, slow speeds, and intermittent operations are involved. They can also operate at high temperatures and are resistant to corrosion, making them ideal for use in harsh environments.
White metal bearings are typically made by melting the alloy and pouring it into a mold around the shaft or rotor. The bearing is then machined to the desired shape and size. White metal bearings require frequent maintenance and lubrication to ensure proper operation and longevity. They are often used in applications such as turbines, compressors, and large electric motors.
