Types Of Babbitt Commonly usedBabbitt has good load carrying capacity between 800 PSI and 1500 PSI Maximum operating temperature for Babbitt is 300º F. In motors 180º F to 190º F is considered running hot. Some turbine applications run as high as 225° F. Many technicians however, will set the alarm at 185º F and trip at 205º F. Melting temperature for common Babbitt varies from 350º F to 475º F bullet Special bonding techniques are required to metallurgically bond Babbitt to metal. Tin based Babbitt (#2) is approximately 89% tin with the remainder being antimony and copper. The hardness of this alloy gives excellent load-carrying characteristics. Lead based Babbitt (#7) is 75% or more lead. Conventional lead- base Babbitt contains antimony and tin, which greatly increase the strength and hardness of lead. This alloy is fully adequate for lower loads and moderate temperatures.
