    Types Of Babbitt Commonly used
    Babbitt 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.
