Babbitt Alloy As A Bearing Material

In 1839, Isaac Babbitt received the first patent for a white metal alloy that showed excellent bearing properties. Since then, the name babbitt has been used for other alloys involving similar ingredients. Babbitt alloys offer an almost unsurpassed combination of compatibility, conformability, and embed ability. They easily adapt their shapes to conform to the bearing shaft and will hold a lubricant film. Foreign matter not carried away by the lubrication is embedded below the surface and rendered harmless. These characteristics are due to babbitt's hard/soft composition. High-tin babbitt alloys, for example, consist of a relatively soft, solid matrix of tin in which are distributed hard copper-tin needles and tin-antimony cuboids. This provides for "excellent run-in" which means the bearing will absorb a lubricant on the surface and hold the lubricant film. Even under severe operating conditions, where high loads, fatigue problems, or high temperature dictate the use of other stronger materials, babbits are often employed as a thin surface coating to obtain the advantage of their good rubbing characteristics.

Grade 2 Babbitt Wire - For Spray Metallization

Grade 2 Babbitt wire provides effective and uniform spray metallization. It exceeds ASTM B23 Grade 2 specification and all federal and legal guidelines for lead-free alloys. Because the ASTM specification was developed for pouring operations, This modified alloy with tighter impurity levels specifically for spray metallization.

Benefits of Babbitt Alloy :

  • No Laminations that would cause deposition problems
  • Non-splitting, virtually weld-free wire with a non-flaking surface to prevent machine feeding problems
  • Available in diameter from .057 to .187"
  • Lead-free composition for environmental safety
  • Produces a soft, pliable wire for easier machine feeding
  • Homogenous structure and tight wire diameter provide even feeding and flame deposition.

Genuine XXXX Nickel Babbitt Alloy

XXXX Nickel Babbitt Alloy is the result of over sixty years constant effort to produce the best bearing alloy, regardless of cost. Today it stands supreme in the field of high-grade bearing metals. It is made only of carefully selected virgin materials and each element is subjected to scientific treatment during the alloying process.

XXXX Nickel Babbitt lasts longer under severe service, because,

  • It holds the oil film
  • It pours freely and fills all liner crevices
  • It's anti-frictional
  • It cannot cut the shaft
  • It resists high temperatures
  • It has high thermal conductivity

XXXX Nickel Babbitt is recommended for use in:

Blowers Dredges Lumber Mills Rock and Gravel Machinery
Cement Mills Electrical machinery Marine Service Steel Mills
Clay Working Machinery Electric Railroads Mining Machinery Sugar Mills
Compressors Engines, Internal Combustion Paper Mills Turbines
Crushers Engines, Steam Pumps
