Bearings • Babbitt Bearings
Babbitt bearings are lined with a soft, white, anti-friction metal that is comprised mainly of copper, antimony, tin and lead. The material, known as Babbitt, is coated over the bore usually to a thickness 0.025 mm to 2.5 mm, and is typically used in integral bearings. Two major families of Babbitt metals are tin based and lead based. Tin-based Babbitt is used for high speed or hard to lubricate bearings, while lead-based Babbitt is used with low speed or heavy load bearings.
